Nudge Security vs Zluri: 2026 Comparison

Nudge Security vs Zluri
Category	UpGuard	Nudge Security	Zluri
General summary	UpGuard manages cyber risk everywhere it lives: your vendors, your internet-facing attack surface, and your workforce. You get one platform that connects all three risk areas instead of separate tools and spreadsheets stitched together. A risk in one surfaces in the others automatically. A breached vendor flags your own exposure. A leaked employee credential links straight to the account and the vendor involved. AI handles the repetitive work of triaging alerts, reviewing vendor evidence, and completing questionnaires. That means lean security teams can run programs that would otherwise need much bigger teams. UpGuard fits mid-market teams, deploys quickly, and slots in without replacing what you already have.	Nudge Security is an agentless SaaS and AI security platform designed to discover and govern employee-adopted applications and identities across the enterprise. It consolidates shadow IT/AI discovery, SSPM, identity governance, third-party and supply-chain risk, and SaaS spend management into a centralized framework that drives compliance directly through automated employee outreach. Because its architecture focuses strictly on the SaaS, identity, and AI layers, the platform does not provide external attack surface management (EASM) or overall organizational security rating scores.	Zluri is a next-generation security platform built to manage both human and machine identities across the enterprise. Its core engine, an intelligence layer called IRIS, normalizes data from SaaS, cloud, and on-premises systems into a relationship graph that maps real-world permissions and access paths. Built on this foundation, Zluri delivers three core capabilities: visibility and intelligence (IVIP), governance and administration (IGA), and security posture management (ISPM)—using a universal connector to cover apps lacking native APIs. Additionally, it features SaaS management capabilities for cost control and shadow IT discovery. The platform, however, focuses strictly on compliance and posture rather than active runtime defense, so it does not offer ITDR, external attack surface management, or security ratings.
Key strengths	UpGuard unifies vendor, attack surface, and workforce risk in one console. Customers describe finally seeing the whole picture, rather than paying for three tools that each cover only part of it. UpGuard also surfaces exposures that ratings tools and scanners miss, without the multi-week delay of a typical scan cycle. Lean teams can run the entire program without expanding headcount or adding a managed service.	Nudge's strength is its patented email and OAuth "genealogy" approach, which surfaces a complete historical inventory of all SaaS, AI, accounts, and integrations within minutes of connecting to Microsoft 365 or Google Workspace. It excels at shadow AI governance (discovering AI agents and monitoring sensitive data shared with chatbots) while its automated "security nudges" (via email, Slack, or Teams) drive behavioral change where traditional security tickets fail. Nudge also accelerates identity governance tasks such as user access reviews and offboarding, while streamlining third-party risk management through real-time supply chain breach alerts and a built-in library of over 200,000 vendor security profiles.	Zluri's primary strength lies in its comprehensive visibility across both human and machine identities, including service accounts and AI agents. Powered by its IRIS intelligence engine and a universal app connector, the platform maps real-world permissions and access paths across SaaS, cloud, and local systems into a single relationship graph. This rich telemetry feeds into its advanced lifecycle automation—seamlessly handling access reviews, joiner/mover/leaver workflows, and segregation-of-duties policies to satisfy major compliance frameworks such as SOC 2, ISO, and HIPAA. Additionally, its posture management features proactively flag risks such as over-privileged or dormant accounts, while retaining tools to optimize software spend and uncover shadow IT.
Key weaknesses	UpGuard focuses on managing live, connected risk, not heavy, standalone compliance software. Full governance features, including policy and controls management, arrive later this year. Teams that need a mature governance, risk, and compliance (GRC) system of record today can run UpGuard alongside one for now. UpGuard also doesn’t translate risk into dollar figures. If financial risk quantification is a must-have, factor that into your evaluation.	Reviewers note that reporting could be more customizable, that coverage of some niche SaaS apps remains limited, and that custom or in-house apps don't always classify correctly, requiring manual reconfiguration and labeling. On the nudge side, some users report that the frequency of automated nudges can cause alert fatigue and would like more flexibility in customizing nudge message templates. A few also found technical-contact assignments unclear, needing periodic adjustment for accuracy.	Reviews cite integration and data setup as limitations for Zluri: some application integrations require additional configuration or validation before usage data is fully accurate, adding onboarding time. Contract and spend-related data depend on the quality and completeness of the uploaded source documents, which requires upfront manual effort. Then there is complexity: Zluri is feature-rich, and the sheer number of features and views can feel overwhelming at first. These are largely onboarding and usability-oriented issues rather than fundamental gaps, and they come from a large, mostly positive review base.
Usability and learning curve	Teams deploy quickly and get up and running without an extended onboarding period. New employees can learn the interface without lengthy training. A single console consolidates workflows that would otherwise require multiple tools, reducing the ongoing burden of learning and maintaining separate systems. Operating the platform doesn’t require a professional services engagement.	Usability is a core strength for Nudge Security. Deployment is effectively instant: an admin connects to Google Workspace or Microsoft 365 via OAuth, and Nudge returns a complete historical inventory within minutes, with no agents, proxies, or network changes required. Users can start a free two-week trial with no credit card required, and the learning curve is low for IT, security, and compliance teams. The friction points are minor and administrative: custom or in-house apps sometimes need manual relabeling to classify correctly, and technical-contact assignments occasionally require adjustment.	Zluri is generally well-regarded for its usability. Onboarding centers on connecting integrations to build the identity and application inventory. Because the platform is broad, spanning visibility, IGA, posture, and SaaS management, reviewers note that the number of features and views can feel overwhelming at first, especially for non-technical users, creating a moderate learning curve to know where to focus. A large, positive review base suggests teams get up to speed effectively, but the main effort is the upfront integration and configuration work.
Cyber risk data accuracy	UpGuard’s data remains current. Vendor postures refresh continuously, and users can initiate a scan on demand instead of waiting for a fixed cycle. UpGuard attributes findings accurately, so teams do not spend weeks correcting assets assigned to the wrong company, a common issue with ratings tools. Threat Monitoring scans the open, deep, and dark web, along with social media, for leaked data, exposed credentials, and brand impersonation. AI filters out noise so the alerts that reach your team are worth acting on.	Nudge delivers comprehensive shadow IT, SaaS, and identity context through email- and OAuth-based discovery to reconstruct a full historical record of SaaS and AI adoption, capturing the long tail that network or CASB tools miss. Enriched by a browser extension and direct integrations, it layers identity telemetry (SSO/MFA status, OAuth scopes, non-human identities) with real-time supply chain breach alerts and 200,000+ vendor security profiles, using AI-powered intelligence to prioritize findings. As a caveat, because its primary discovery method is partly inferential, custom or in-house apps may occasionally misclassify and require relabeling; also, the deepest configuration data is limited to directly integrated apps, and data remains strictly scoped to the SaaS/identity/AI domains rather than external scanning.	Zluri excels at asset discovery by aggregating signals from direct APIs, identity providers, finance systems, and a browser agent. Its IRIS intelligence layer normalizes these multi-source inputs to map out exact permission paths for both human and machine identities across SaaS, cloud, and custom environments. While this provides high-fidelity visibility into active entitlements, reviewers note that data reliability varies with integration coverage, requiring manual validation for less-supported apps. Additionally, spend insights depend strictly on the completeness of uploaded contract documents, and the underlying data engine is structurally optimized for identity governance rather than live security threat telemetry.
Vendor risk management features	UpGuard runs the complete third-party risk management (TPRM) process in one platform: onboarding, assessing, remediating, monitoring, and reporting on vendors. Each vendor’s live external exposure and any linked leaked credentials appear directly within the vendor program, so teams can act on verified risk instead of relying on paperwork. AI-powered security questionnaires read vendor evidence and complete assessments automatically, cutting completion time by up to 95%. Instant risk assessments return a point-in-time report in under a minute, mapped to frameworks like ISO 27001 and NIST CSF 2.0.	While not a full TPRM platform, Nudge offers more third-party risk capability than most SaaS-security tools, providing a live view of all active SaaS and AI apps, app-to-app OAuth integrations, and non-human identities touching company data. It accelerates vendor due diligence through its built-in library of SaaS vendor security profiles and delivers real-time supply chain breach alerts. However, it lacks comprehensive TPRM lifecycle workflows—such as custom security questionnaires, formal risk assessments and scoring, and structured remediation tracking—meaning organizations requiring full vendor lifecycle management will still need a dedicated VRM tool.	Zluri is not a dedicated third-party/vendor risk management (TPRM) platform, and lacks the security-oriented VRM lifecycle of a dedicated solution. Its vendor-related capabilities are operational and governance-focused: it manages SaaS vendor contracts, renewals, and spend, tracks which third-party (and AI) apps are in use, and governs access to them, including surfacing risky or over-permissioned third-party integrations. This provides useful visibility into third-party apps in an environment and helps control access, but organizations that need vendor security due diligence and assessments would require a dedicated VRM/TPRM tool.
Attack surface management features	UpGuard continuously monitors your internet-facing footprint. It maps assets, flags exposures such as misconfigurations, expired certificates, and open ports, and ranks remediation priorities. The UpGuard platform also detects typosquatting and lookalike domains set up to impersonate your brand before they’re used for phishing. Because attack surface monitoring runs alongside vendor and workforce risk, an exposed asset or leaked credential automatically links to the person and vendor involved. This gives teams visibility into both external exposure and vendor risk in a single view.	Nudge does not perform traditional external attack surface management; it does not scan or monitor internet-facing infrastructure such as domains, IPs, exposed services, or certificates. It does, however, explicitly address the "SaaS attack surface": by discovering every SaaS and AI app, account, OAuth integration, and non-human identity employees create, it maps and helps reduce the identity and SaaS-driven exposure that sits outside the network perimeter, what Nudge calls the "Workforce Edge." Organizations needing conventional, internet-facing ASM would still require a dedicated tool.	Zluri's Identity Security Posture Management (ISPM) notably minimizes enterprise exposure by mapping access paths across all human and machine accounts. The platform actively surfaces internal risks—such as over-privileged users, toxic access combinations, dormant accounts, and unmonitored shadow apps—before guiding teams through prioritized remediation and access reviews. However, this defense is strictly identity-centric. Zluri does not scan external, internet-facing infrastructure such as domains, IPs, or certificates, so organizations that require traditional attack surface management (ASM) will still need a dedicated tool.
Customer support	UpGuard supports every customer across all plan tiers, from the smallest plan to the largest. Support teams assist with both technical setup and larger program decisions. Customers frequently cite responsive, hands-on support as a reason they continue with UpGuard.	Nudge employs a low-touch, self-service support model in which a unified "Product Success" team handles everything from pre-sales to ongoing adoption, rather than relying on traditional Customer Success managers. Support relies on extensive self-service resources (a knowledge base, FAQs, API documentation, a public status page, and demo content) supplemented by email support. Organizations requiring a dedicated, named account manager or high-touch enterprise support may find this approach lighter than typical industry norms.	Customer support is frequently praised across Zluri's large G2 review base, with customers highlighting responsive support and hands-on customer success and onboarding assistance. Self-service resources are well developed: Help Docs, a support portal, Zluri Academy for training and enablement, and a Trust Center. New customers are typically guided through onboarding and integration setup by Zluri's team, which helps offset the platform's breadth and upfront configuration effort. The main caveat is that Zluri does not publicly document formal support tiers or SLAs, so specifics are set during contracting.
Workflow automation	Risk Automations turns a risk signal into action across the platform, with no code and no engineering ticket. On the vendor side, it automates onboarding from questionnaire data, triages vendor score drops, schedules recurring vendor reports, and opens remediation tickets in ServiceNow or Jira. On the threat side, a Breach Risk detection can trigger a workflow that alerts Teams or Slack and runs a system-level fix, like blocking a malicious IP or forcing a credential reset. This is the difference between a tool that reports on risk and one that resolves it.	Nudge's workflow playbooks and policy-driven guardrails codify governance tasks to automate the safe adoption of SaaS and AI without manual gatekeeping. Its security nudges automatically message employees via email, Slack, or Teams to prompt self-remediation the moment issues arise, such as new shadow apps, missing MFA, or risky OAuth grants, scaling enforcement without generating IT tickets. Common automated workflows include employee offboarding, SSO onboarding, app approval and justification, and user access reviews, though this enforcement is scoped to the specific applications and identity systems Nudge connects to.	Zluri leverages a no-code engine to automate the entire identity lifecycle—handling onboarding provisioning, role changes, and access revocation seamlessly. Beyond core lifecycle management, it supports self-service requests and compliance audits with features such as automated reviews, one-click remediation, and segregation-of-duties enforcement. It also extends into posture management by automatically flagging and resolving dormant or over-privileged access. While the absolute reach of these automated workflows is ultimately bound to your target systems, Zluri's universal connector allows teams to easily extend this governance to custom or legacy apps that lack native APIs.
Artificial intelligence features	UpGuard’s AI performs specific, defined tasks, rather than vague “AI-powered” work. The AI Threat Analyst sorts and scores incoming threats across your attack surface, the dark web, and social media. It clears out approximately 60% of alerts as noise, so your team only reviews what matters. The same triage logic extends to vendor and workforce signals as well. Every AI result carries a citation back to the source, so your team can verify it before acting.	Nudge's AI capabilities split focus between governing external AI usage and applying AI within the platform. For governance, it discovers shadow AI apps and browser-based agents, monitors chatbot conversations to detect sensitive data shared through file uploads or copy-pasting, and enforces policy-driven guardrails to ensure safe adoption. The product leverages AI-powered risk intelligence to continuously identify, score, and prioritize threats across the entire SaaS and AI attack surface. The platform does not feature a branded generative AI assistant or copilot, concentrating its AI value entirely on discovery, governance, and automated risk prioritization.	AI and machine learning underpin Zluri's IRIS identity intelligence layer, which analyzes identity and access signals to detect access anomalies and risk, prioritize issues by impact, and recommend clear remediation actions. AI also powers discovery and classification by automatically identifying and categorizing SaaS and AI apps, including shadow IT, and supports access reviews with recommendations that speed approve/revoke decisions. Zluri also monitors AI apps and helps govern non-human and AI agent identities. These are meaningful, embedded intelligence capabilities oriented toward identity governance and risk, though Zluri positions them as an intelligence and decisioning layer rather than a broad, branded generative AI copilot.
API and integrations	A well-documented REST API and webhooks let teams pull risk data into their own tools and trigger actions programmatically, without waiting on engineering support. For no-code work, Risk Automations adds more than 100 native integrations, including Jira, ServiceNow, Microsoft Entra, Slack, and Cloudflare. A Universal API Connector Node extends its reach to any open API.	Nudge discovers the entire SaaS and AI estate via OAuth and email genealogy without requiring individual connectors, ensuring long-tail visibility is completely independent of prebuilt integrations. For deep posture management and action, it provides direct integrations with business-critical platforms (Okta, Salesforce, Snowflake, Zoom), a browser extension, and communication channels (email, Slack, Teams) for driving nudges. Programmatic access is available via a documented public REST API. While universal discovery applies broadly, deep configuration data and remediation capabilities remain concentrated on major platforms, limiting integration depth for niche SaaS apps.	Zluri features one of the largest integration catalogs in its category, providing hundreds of deep, bi-directional connectors across identity providers (Okta, Entra, Google), HRMS, finance, and core SaaS apps to power both asset discovery and automated provisioning. To eliminate the blind spots of connector-only platforms, its Universal Identity Connector (part of IRIS) seamlessly extends this governance to custom, cloud, and on-premises applications. While an open API supports broader custom data exchange, user reviews note a key caveat: integration depth varies by app, and certain platforms require extra configuration or validation before returning fully reliable data.
Purchasing & licensing transparency	UpGuard publishes its pricing rather than hiding it behind a sales call. A free tier lets teams monitor up to five vendors and use Trust Exchange, UpGuard’s AI-powered questionnaire tool, at no cost. Paid Vendor Risk plans start at USD 1,750 per month, billed annually. Teams can start with one product and add others as they scale. One license covers both monitoring and assessments, so pricing doesn’t fragment across separate products.	Nudge Security provides a highly transparent pricing model based on active workspace users (licensed Google Workspace or Microsoft 365 mailboxes, excluding archived or suspended accounts), with no seat limits or extra charges for Nudge platform users and SSO included. Organizations under 150 accounts pay a flat $750/month, teams with 150–2,500 accounts pay $5 per active user/month, and deployments over 2,500 accounts receive custom ELA pricing. A 14-day free trial is available without a credit card, with payment options that let customers pay upfront or as they go. While all plans include the core platform, advanced configuration and integration-posture features for critical apps are paid add-ons, and the software is also available via the AWS Marketplace.	Zluri does not publish public pricing. Pricing is quote-based and obtained through a sales demo, typically scaled by organization size and the products/modules selected; third-party marketplaces have estimated roughly $4–8 per user per month and a tiered structure (e.g., Standard/Professional/Enterprise), but Zluri does not confirm these publicly. Zluri's website offers an ROI calculator to estimate value, and evaluation is sales-led (demo/proof of concept) rather than a self-service free trial. Ultimately, cost and packaging are opaque and require a sales conversation.
Customers	UpGuard customers include Intercontinental Exchange (NYSE: ICE), Morningstar, TDK, PagerDuty, Hopin, and IAG. Read UpGuard’s customer stories to learn more.	Nudge publicly references customers and endorsers, including Netflix, Snowflake, Watershed, KarmaCheck, and Unify Consulting, with security and IT leaders at Netflix and Snowflake citing its use across their organizations. The customer base skews toward technology, SaaS, and modern mid-market and enterprise teams. While it includes a couple of marquee names (Netflix and Snowflake), the publicly disclosed roster is relatively modest in breadth compared with that of larger, established vendors.	Zluri publishes an extensive set of named customer case studies across mid-market and enterprise organizations, many with quantified outcomes. Examples include BambooHR, Nuvei, Narvar, Guesty, and Underdog (others featured include Kasada, Tripledot Studios, Pano AI, Radicle Health, and Anzu), with results such as large IT-hour savings, faster provisioning, and reduced audit time. The customer base skews toward technology, fintech, and mid-to-large enterprises managing significant SaaS and identity sprawl. The roster is broad and well-documented, though it leans toward recognizable tech and mid-market names rather than marquee Fortune 100 brands.
G2 rating Accurate as of March 2025	More than 700 verified reviews give UpGuard a 4.5 out of 5 rating on G2. UpGuard also holds G2’s top ranking as the leader in Third-Party & Supplier Risk Management for 15 consecutive quarters. The 2026 G2 Best Software Awards recognized UpGuard as one of the Top 100 Global Software Companies. Among verified reviewers, 98% give UpGuard four- or five-star ratings, and 94% approve of its product direction.	4.5, based on 16 reviews.	4.6, based on 177 reviews.

Vendor risk management features

UpGuard runs the complete third-party risk management (TPRM) process in one platform: onboarding, assessing, remediating, monitoring, and reporting on vendors. Each vendor’s live external exposure and any linked leaked credentials appear directly within the vendor program, so teams can act on verified risk instead of relying on paperwork. AI-powered security questionnaires read vendor evidence and complete assessments automatically, cutting completion time by up to 95%. Instant risk assessments return a point-in-time report in under a minute, mapped to frameworks like ISO 27001 and NIST CSF 2.0.

While not a full TPRM platform, Nudge offers more third-party risk capability than most SaaS-security tools, providing a live view of all active SaaS and AI apps, app-to-app OAuth integrations, and non-human identities touching company data. It accelerates vendor due diligence through its built-in library of SaaS vendor security profiles and delivers real-time supply chain breach alerts. However, it lacks comprehensive TPRM lifecycle workflows—such as custom security questionnaires, formal risk assessments and scoring, and structured remediation tracking—meaning organizations requiring full vendor lifecycle management will still need a dedicated VRM tool.

Zluri is not a dedicated third-party/vendor risk management (TPRM) platform, and lacks the security-oriented VRM lifecycle of a dedicated solution. Its vendor-related capabilities are operational and governance-focused: it manages SaaS vendor contracts, renewals, and spend, tracks which third-party (and AI) apps are in use, and governs access to them, including surfacing risky or over-permissioned third-party integrations. This provides useful visibility into third-party apps in an environment and helps control access, but organizations that need vendor security due diligence and assessments would require a dedicated VRM/TPRM tool.

Attack surface management features

UpGuard continuously monitors your internet-facing footprint. It maps assets, flags exposures such as misconfigurations, expired certificates, and open ports, and ranks remediation priorities. The UpGuard platform also detects typosquatting and lookalike domains set up to impersonate your brand before they’re used for phishing.

Nudge's AI capabilities split focus between governing external AI usage and applying AI within the platform. For governance, it discovers shadow AI apps and browser-based agents, monitors chatbot conversations to detect sensitive data shared through file uploads or copy-pasting, and enforces policy-driven guardrails to ensure safe adoption. The product leverages AI-powered risk intelligence to continuously identify, score, and prioritize threats across the entire SaaS and AI attack surface. The platform does not feature a branded generative AI assistant or copilot, concentrating its AI value entirely on discovery, governance, and automated risk prioritization.

AI and machine learning underpin Zluri's IRIS identity intelligence layer, which analyzes identity and access signals to detect access anomalies and risk, prioritize issues by impact, and recommend clear remediation actions. AI also powers discovery and classification by automatically identifying and categorizing SaaS and AI apps, including shadow IT, and supports access reviews with recommendations that speed approve/revoke decisions. Zluri also monitors AI apps and helps govern non-human and AI agent identities. These are meaningful, embedded intelligence capabilities oriented toward identity governance and risk, though Zluri positions them as an intelligence and decisioning layer rather than a broad, branded generative AI copilot.

API and integrations

A well-documented REST API and webhooks let teams pull risk data into their own tools and trigger actions programmatically, without waiting on engineering support. For no-code work, Risk Automations adds more than 100 native integrations, including Jira, ServiceNow, Microsoft Entra, Slack, and Cloudflare. A Universal API Connector Node extends its reach to any open API.

Nudge discovers the entire SaaS and AI estate via OAuth and email genealogy without requiring individual connectors, ensuring long-tail visibility is completely independent of prebuilt integrations. For deep posture management and action, it provides direct integrations with business-critical platforms (Okta, Salesforce, Snowflake, Zoom), a browser extension, and communication channels (email, Slack, Teams) for driving nudges. Programmatic access is available via a documented public REST API. While universal discovery applies broadly, deep configuration data and remediation capabilities remain concentrated on major platforms, limiting integration depth for niche SaaS apps.

Zluri features one of the largest integration catalogs in its category, providing hundreds of deep, bi-directional connectors across identity providers (Okta, Entra, Google), HRMS, finance, and core SaaS apps to power both asset discovery and automated provisioning. To eliminate the blind spots of connector-only platforms, its Universal Identity Connector (part of IRIS) seamlessly extends this governance to custom, cloud, and on-premises applications. While an open API supports broader custom data exchange, user reviews note a key caveat: integration depth varies by app, and certain platforms require extra configuration or validation before returning fully reliable data.

Purchasing & licensing transparency

UpGuard publishes its pricing rather than hiding it behind a sales call. A free tier lets teams monitor up to five vendors and use Trust Exchange, UpGuard’s AI-powered questionnaire tool, at no cost. Paid Vendor Risk plans start at USD 1,750 per month, billed annually. Teams can start with one product and add others as they scale. One license covers both monitoring and assessments, so pricing doesn’t fragment across separate products.

Nudge Security provides a highly transparent pricing model based on active workspace users (licensed Google Workspace or Microsoft 365 mailboxes, excluding archived or suspended accounts), with no seat limits or extra charges for Nudge platform users and SSO included. Organizations under 150 accounts pay a flat $750/month, teams with 150–2,500 accounts pay $5 per active user/month, and deployments over 2,500 accounts receive custom ELA pricing. A 14-day free trial is available without a credit card, with payment options that let customers pay upfront or as they go. While all plans include the core platform, advanced configuration and integration-posture features for critical apps are paid add-ons, and the software is also available via the AWS Marketplace.

Zluri does not publish public pricing. Pricing is quote-based and obtained through a sales demo, typically scaled by organization size and the products/modules selected; third-party marketplaces have estimated roughly $4–8 per user per month and a tiered structure (e.g., Standard/Professional/Enterprise), but Zluri does not confirm these publicly. Zluri's website offers an ROI calculator to estimate value, and evaluation is sales-led (demo/proof of concept) rather than a self-service free trial. Ultimately, cost and packaging are opaque and require a sales conversation.

Nudge Security vs Zluri product overview

Learn more about the products and how they compare.

We assess three user risk solutions — Nudge Security, Zluri, and UpGuard — to help you make an informed decision before investing in the right solution for your needs.

Nudge Security Overview

Nudge Security is an agentless SaaS and AI security platform that discovers and governs employee-adopted applications and identities across the enterprise. It consolidates shadow IT and AI discovery, SaaS security posture management (SSPM), identity governance, third-party and supply-chain risk, and SaaS spend management into a single framework, driving compliance through automated employee outreach. Its architecture is scoped to the SaaS, identity, and AI layers, so it doesn’t provide external attack surface management or organization-wide security ratings.

Zluri Overview

Zluri is a security platform built to manage both human and machine identities across the enterprise. Its intelligence layer, IRIS, normalizes data from SaaS, cloud, and on-premises systems into a relationship graph that maps real-world permissions and access paths, feeding three core capabilities: visibility and intelligence (IVIP), governance and administration (IGA), and security posture management (ISPM). It also includes SaaS management for cost control and shadow IT discovery, but focuses on compliance and posture rather than active runtime defense, so it doesn’t offer ITDR, external attack surface management, or security ratings.

UpGuard Overview

UpGuard is a third-party risk and attack surface management platform that helps global organizations prevent data breaches, monitor third-party vendors, and improve their security posture. UpGuard’s platform uses proprietary security ratings, data leak detection capabilities, and remediation workflows to proactively identify security exposures. UpGuard’s all-in-one third-party risk and attack surface management software intelligently groups risks into six categories: website risks, email security, network security, phishing & malware, reputation risk, and brand protection.

Usability and the learning curve

Nudge Security: Deployment is effectively instant: an admin connects to Google Workspace or Microsoft 365 via OAuth, and Nudge returns a complete historical inventory within minutes, with no agents, proxies, or network changes required. A 14-day free trial requires no credit card, and the learning curve is low for IT, security, and compliance teams; the main friction points are minor, such as custom or in-house apps occasionally needing manual relabeling.

Zluri: Onboarding centers on connecting integrations to build the identity and application inventory, and reviewers generally rate the platform as easy to use. Because it spans visibility, IGA, posture, and SaaS management, the number of features and views can feel overwhelming at first, creating a moderate learning curve to know where to focus, though a large, positive review base suggests teams get up to speed once that initial setup is done.

UpGuard: High-level summation of risk with the ability to drill down into precise technical details. Each risk is prioritized based on extensive research conducted by the in-house security team, and where possible remediation and protection suggestions are provided.

Capabilities

Nudge Security: Nudge Security works through a patented email and OAuth “genealogy” approach that reconstructs a complete historical inventory of SaaS, AI, accounts, and integrations within minutes of connecting to Microsoft 365 or Google Workspace. Its strength is breadth: it pairs shadow AI governance with automated “security nudges” sent over email, Slack, or Teams to drive self-remediation, plus identity governance tasks like access reviews and a built-in library of over 200,000 vendor security profiles. Its limitation is that discovery is partly inferential, so custom or in-house apps can misclassify, and it doesn’t provide external attack surface management or security ratings of its own.

Zluri: Zluri is an identity-first platform: its IRIS engine maps human and machine identities and their access paths into a single relationship graph, then layers lifecycle automation, access reviews, and posture checks on top to satisfy frameworks like SOC 2 and HIPAA. Its strength is breadth: a large integration catalog and a universal connector extend that governance to apps and on-premises systems without native APIs. Its limitation is scope: the platform stops at compliance and posture, offering no ITDR, external attack surface management, or security ratings, and the number of features can feel overwhelming to configure at the outset.

UpGuard: Offers real-time visibility into any third-party vendor’s risk posture and security rating along with total automation for managing vendor due diligence and remediation programs.

Community support

Nudge Security: Support runs on a low-touch, self-service model: a unified “Product Success” team handles pre-sales through ongoing adoption in place of a dedicated Customer Success manager, backed by a knowledge base, FAQs, API documentation, a public status page, and demo content, supplemented by email support.

Zluri: Reviewers frequently praise Zluri’s customer support, citing hands-on onboarding assistance and responsiveness. Self-service resources include Help Docs, a support portal, Zluri Academy for training, and a Trust Center, though formal support tiers and SLAs aren’t publicly documented.

UpGuard: UpGuard Summit brings together a community of security leaders from leading companies, explores the future of security, and helps businesses stay secure. The UpGuard cybersecurity and risk management blog is updated four times a week and the breach research blog has uncovered and secured some of the largest data breaches. UpGuard’s free weekly Breach Newsletter informs 20,000+ subscribers of the latest global data breaches.

Release rate

Nudge Security: Nudge Security maintains a public changelog with an RSS feed, posting recurring updates such as new AI-agent discovery sources, browser-extension improvements, and business-criticality triage filters. There’s no fixed release schedule, but updates ship on an ongoing, rolling basis.

Zluri: No formal, version-by-version changelog is published. Instead, Zluri posts recurring “Zluri Updates” recaps on its blog, roughly monthly, covering new features and integrations, and it reported shipping over 250 product updates in 2024. There’s no fixed release schedule beyond that regular cadence.

UpGuard: UpGuard has adopted DevOps principles internally to develop, test, and release software continuously, ensuring fast, consistent, and safe releases. UpGuard has a regular release rate every two weeks, with all features, changes, and improvements listed under UpGuard Release Notes.

Pricing and support

Nudge Security: Pricing is based on active workspace user accounts (licensed Google Workspace or Microsoft 365 mailboxes). Organizations under 150 accounts pay a flat $750 per month; teams with 150 to 2,500 accounts pay $5 per active user per month; larger deployments get custom ELA pricing. There’s no free plan, but a 14-day free trial requires no credit card. See Nudge Security’s pricing.

Zluri: Pricing isn’t published. It’s quote-based, scaled by organization size and the modules selected (identity visibility, IGA, ISPM, and SaaS management), and obtained through a sales demo; third-party estimates put costs around $4 to $8 per user per month, though Zluri doesn’t confirm this. There’s no free plan, and evaluation runs sales-led rather than through a self-service trial. See Zluri’s pricing.

UpGuard: UpGuard has a fully transparent and publicly accessible pricing model which you can view here. If you have any questions, please email sales@upguard.com.

API and extensibility

Nudge Security: Nudge discovers the SaaS and AI estate through OAuth and email genealogy without requiring individual connectors, and a documented public REST API supports programmatic access. Deep posture management and remediation are concentrated on major platforms it integrates with directly, so integration depth is thinner for niche SaaS apps.

Zluri: An open API supports custom data exchange, and Zluri’s Universal Identity Connector extends governance to custom, cloud, and on-premises applications that lack native APIs. Integration depth varies by app, and some platforms require extra configuration before returning fully reliable data.

UpGuard: Offers a standard API to pull data from UpGuard’s platform into other enterprise applications.

Third-party integrations

Nudge Security: Direct integrations cover business-critical platforms including Okta, Salesforce, Snowflake, and Zoom, alongside a browser extension and communication channels like email, Slack, and Teams for delivering nudges.

Zluri: Hundreds of deep, bi-directional connectors cover identity providers (Okta, Microsoft Entra, Google), HRMS and finance systems, and core SaaS apps, one of the larger catalogs in its category.

UpGuard: Integrates with Zapier to enable connections to 3,000+ apps; GRC platforms, ticketing systems like JIRA; VRM solutions like ServiceNow, and more.
