Why Vendor Assessment Matters for SOC 2
Third-party vendors represent one of the biggest security risks for modern organizations. SOC 2 auditors will examine how you manage vendor relationships, especially those that process customer data or have access to your production systems.
Risk Management
Proper vendor assessment helps identify and mitigate security risks before they impact your organization.
Compliance
SOC 2 requires documented vendor management processes and evidence of ongoing oversight.
Incident Prevention
Many security breaches originate from compromised third-party vendors or weak vendor security practices.
Vendor Risk Classification
Start by classifying your vendors based on their access to sensitive data and business criticality. This determines the level of due diligence required.
Critical Risk
Vendors with access to production systems or customer data
High Risk
Vendors that process or store sensitive company data
Medium Risk
Vendors with limited access to internal systems
Low Risk
Vendors with minimal security impact
