Nudge Security vs Obsidian Security: 2026 Comparison

Nudge Security vs Obsidian Security
Category	UpGuard	Nudge Security	Obsidian Security
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.	Obsidian Security unifies SaaS and AI security for the enterprise. The platform combines SSPM, third-party integration risk, AI governance, and Identity Threat Detection and Response (ITDR) to deliver continuous visibility and runtime protection across humans, apps, and AI agents. By correlating real-time activity and breach intelligence in a knowledge graph with self-learning detection, Obsidian protects the core SaaS and identity layers—though it does not provide external attack surface management (EASM) or security-rating scores.
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.	Obsidian's core strength lies in its deep detection capabilities. By correlating real-time activity, app configurations, and breach intelligence within a knowledge graph with self-learning detection, it rapidly stops live threats like account takeovers, token compromise, and OAuth abuse (ITDR). The platform also unifies SaaS and AI security, managing posture (SSPM) and governing AI agent usage across human, app, and machine identities. Additionally, its SaaS supply chain security proactively isolates risky third-party integrations before an external vendor breach can cascade into your environment.
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.	The most consistently cited product limitation reviewers note is that reporting is limited, and some dashboards are not particularly functional or helpful, though Obsidian is actively improving this area. Relatedly, as a relatively new SSPM entrant, some reviewers note that it lags behind more established tools in certain areas, particularly in its threat catalog and the refinement of some workflows.
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.	Obsidian is agentless and API-based, so getting started takes minutes with no agents to deploy or rules to write. Day-to-day, users value having SaaS and AI activity correlated in one place, which speeds up investigations. Overall, the learning curve is reasonable for an enterprise security platform, helped considerably by Obsidian's onboarding support.
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.	Obsidian's core advantage is its high-fidelity data foundation. By normalizing rich, real-time activity and granular in-app configurations against a massive breach-intelligence dataset, it ensures exceptional data accuracy from the jump. This precise telemetry feeds a knowledge graph and self-learning detection models to deliver high-fidelity, low-noise detections of token abuse and misconfigurations. However, this data fidelity depends entirely on direct, connected integrations rather than external scanning, and its threat catalog is still maturing within the SaaS and identity layers.
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.	Obsidian is not a dedicated third-party/vendor risk management (TPRM) platform and lacks core VRM lifecycle workflows such as vendor security questionnaires, formal assessments and scoring, and structured remediation tracking across a vendor portfolio. It does, however, discover and reduce risky third-party SaaS integrations and OAuth grants, surfacing the privileges third parties hold, and detects third-party and supply-chain threats early to contain the blast radius before a vendor breach cascades into the customer's environment. This delivers meaningful third-party risk reduction at the integration and threat layers, but organizations that need full vendor due diligence and lifecycle management would still require a dedicated VRM 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.	Obsidian 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. Its relevance to the attack surface is limited to the SaaS and identity layers. It reduces the SaaS attack surface by discovering shadow SaaS, mapping and curbing risky third-party API integrations and OAuth grants, and identifying excessive privileges and exposed accounts. Organizations needing conventional, internet-facing ASM would still require 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 one of Obsidian's most consistently praised attributes. Enterprise customers describe it as exceptional, responsive, and proactive. The model is high-touch, with customers supported by dedicated Customer Success Managers, Technical Account Managers (TAMs), and account teams that guide implementation, prioritize feature requests, and work closely with the customer's security organization. The main caveat is that Obsidian does not publicly document standard support tiers or SLAs (these are arranged through enterprise agreements), and its self-service support resources are lighter than those of larger, more established vendors.
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.	Obsidian supports automation across detection, response, and governance. Through its ITDR capabilities, it detects identity threats and enables fast, guided response to contain them before they become incidents, and it applies runtime guardrails and policy enforcement to AI agents and GenAI usage. On the posture side, it offers guided and automated remediation for misconfigurations, excessive privileges, and risky third-party OAuth grants, including the revocation of inappropriate integrations. An action control plane turns its risk intelligence into enforcement, and integrations with tools such as ServiceNow, Jira, and Splunk let teams route alerts, tickets, and evidence into existing workflows. As with any SaaS/identity platform, the reach of automated enforcement depends on the connected apps and downstream tools.
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.	Obsidian embeds AI as a core architectural capability rather than an add-on, applying it in two distinct directions. Internally, self-learning detection models leverage network effects to sharpen threat intelligence, while an interactive AI Assistant accelerates analyst triage and investigations. Externally, the platform delivers comprehensive AI governance, including AI-SPM, shadow AI discovery, prompt security, and agent runtime protection, across major enterprise ecosystems such as Microsoft Copilot, ChatGPT, Amazon Bedrock, Google Vertex, Anthropic Claude, and Salesforce Agentforce.
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.	Obsidian's agentless, API-based model delivers deep integrations across core SaaS platforms (M365, Google Workspace, Okta, Salesforce, Snowflake, Databricks, GitHub, ServiceNow, Workday) and major AI ecosystems (Bedrock, Claude, ChatGPT, Vertex, Copilot, OpenAI, Agentforce). Identity providers like Okta, Entra, and Google anchor this telemetry, routing alerts to operational tools like Jira and Splunk, while a browser extension extends visibility to track users in transit and compromised accounts. While this ecosystem is deep, it is purpose-built for the SaaS, AI, and identity domains rather than serving as a general-purpose marketplace.
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.	Obsidian publishes a clear, modular tier structure: Free, Foundations, and Advanced, with detailed feature breakdowns for each. Obsidian offers a free plan (up to 1,000 users) covering SaaS-sprawl and shadow-AI discovery, plus spear-phishing detection, alongside a free trial. However, it does not publish dollar pricing for its paid tiers: both Foundations (discovery and governance) and Advanced (detection, runtime defense, and incident response) are quote-only, so actual cost requires contacting sales. Pricing is generally based on headcount and scales with the modules a team selects.
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.	Obsidian publicly cites a track record with major enterprise and technology brands, listing companies such as Snowflake, T-Mobile, Databricks, S&P Global, and Seagate among its users, as well as organizations such as Wyndham, Algolia, BigCommerce, AAA, and Upwork. This customer base heavily skews toward large-scale, data-centric organizations, reflecting Obsidian's enterprise focus on complex SaaS and AI environments.

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.

Obsidian's agentless, API-based model delivers deep integrations across core SaaS platforms (M365, Google Workspace, Okta, Salesforce, Snowflake, Databricks, GitHub, ServiceNow, Workday) and major AI ecosystems (Bedrock, Claude, ChatGPT, Vertex, Copilot, OpenAI, Agentforce). Identity providers like Okta, Entra, and Google anchor this telemetry, routing alerts to operational tools like Jira and Splunk, while a browser extension extends visibility to track users in transit and compromised accounts. While this ecosystem is deep, it is purpose-built for the SaaS, AI, and identity domains rather than serving as a general-purpose marketplace.

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.

Obsidian publishes a clear, modular tier structure: Free, Foundations, and Advanced, with detailed feature breakdowns for each. Obsidian offers a free plan (up to 1,000 users) covering SaaS-sprawl and shadow-AI discovery, plus spear-phishing detection, alongside a free trial. However, it does not publish dollar pricing for its paid tiers: both Foundations (discovery and governance) and Advanced (detection, runtime defense, and incident response) are quote-only, so actual cost requires contacting sales. Pricing is generally based on headcount and scales with the modules a team selects.

Nudge Security vs Obsidian Security product overview

Learn more about the products and how they compare.

We assess three user risk solutions — Nudge Security, Obsidian Security, 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.

Obsidian Overview

Obsidian Security unifies SaaS and AI security for the enterprise, combining SaaS security posture management (SSPM), third-party integration risk, AI governance, and Identity Threat Detection and Response (ITDR). It correlates real-time activity and breach intelligence in a knowledge graph, using self-learning detection to catch threats like account takeovers, token compromise, and OAuth abuse. AI governance extends to major ecosystems including Microsoft Copilot, ChatGPT, Amazon Bedrock, Google Vertex, Anthropic Claude, and Salesforce Agentforce.

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.

Obsidian: Getting started takes minutes, since the platform is agentless and API-based with no agents to deploy. Users cite correlating SaaS and AI activity in one place as a time-saver during investigations, and describe the overall learning curve as reasonable for an enterprise platform.

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.

Obsidian: Obsidian protects the SaaS and identity layer directly, correlating real-time activity, app configurations, and breach intelligence in a knowledge graph to catch live threats such as account takeovers and OAuth abuse, and applying the same model to govern AI agent usage. Reporting is the most cited weakness: dashboards are described as limited. As a newer SSPM entrant, its threat catalog is still maturing relative to established players.

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.

Obsidian: Support is high-touch: customers get dedicated Customer Success Managers and Technical Account Managers who guide implementation and prioritize feature requests. Standard support tiers and SLAs aren’t publicly documented; they’re arranged through enterprise agreements.

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.

Obsidian: No dedicated changelog, but product updates appear as “Product Spotlight” posts within its blog, alongside its news, research, and security-advisory content. Updates are tied to feature launches rather than a fixed release schedule.

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.

Obsidian: A clear tier structure is published: Free, Foundations, and Advanced. The free plan covers up to 1,000 users for SaaS-sprawl and shadow-AI discovery plus spear-phishing detection; Foundations and Advanced are quote-only, priced by headcount and scaled by modules selected. A free trial is also available. See Obsidian Security’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.

Obsidian: An agentless, API-based architecture pulls real-time activity, app configuration, and identity telemetry straight from connected platforms rather than requiring installed agents, then routes alerts and supporting evidence to operational tools like Jira and Splunk for response. A browser extension extends that visibility further, tracking users and compromised accounts as they move between apps and devices.

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.

Obsidian: Core SaaS platforms connect directly: Microsoft 365, Google Workspace, Okta, Salesforce, Snowflake, Databricks, GitHub, ServiceNow, and Workday. Major AI ecosystems connect too (Bedrock, Claude, ChatGPT, Vertex, Copilot, OpenAI, Agentforce), with alerts routed to Jira and Splunk.

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