The vendor due diligence process is essential for organizations to ensure that their third-party vendors, who typically have access to or manage[ sensitive data](https://www.upguard.com/blog/sensitive-data) and systems, follow established cybersecurity standards and practices.

[Find out how UpGuard helps businesses assess new vendors >](https://www.upguard.com/product/vendorrisk) ## Why is vendor due diligence important? Because organizations increasingly rely on[ third-party vendors](https://www.upguard.com/blog/third-party-vendor) for various services, bringing on more vendors also increases their risk of a[ data breach](https://www.upguard.com/blog/data-breach). This dependency introduces new cyber risks, making [vendor reviews in cybersecurity](https://www.upguard.com/blog/vendor-security-review) a necessary precautionary measure and a critical component of an organization's overall cybersecurity strategy. Organizations can limit their risks and liabilities (such as reputational risk or operational risk) by properly vetting potential vendors during the procurement or vendor selection process and building stronger vendor relationships by establishing security expectations and goals. This is typically done through due diligence questionnaires (DDQ), which are broader in scope than[ security questionnaires](https://www.upguard.com/product/security-questionnaires). However, the vendor due diligence process doesn’t stop after onboarding. Instead, organizations must establish a plan to[ continue monitoring](https://www.upguard.com/blog/continuous-security-monitoring) the vendor and ensure they uphold the security requirements agreed upon during contract negotiations and SLAs throughout the vendor’s lifecycle.
