SOC 2 Compliance

Implement SOC 2 Trust Services Criteria controls, evidence collection, and continuous compliance monitoring for Type I and Type II audits.

When to Use

• Preparing for a SOC 2 Type I or Type II audit
• Mapping existing controls to Trust Services Criteria
• Automating evidence collection for auditor requests
• Building continuous compliance monitoring into CI/CD
• Onboarding new services and ensuring SOC 2 control coverage

Best Practices

• Start with a gap assessment to understand current control maturity before engaging an auditor
• Automate evidence collection to reduce the burden of auditor requests and ensure consistency
• Map each control to a specific tool, owner, and evidence artifact for traceability
• Implement continuous monitoring rather than point-in-time checks for Type II readiness
• Maintain a central evidence repository organized by control criteria
• Conduct quarterly internal reviews to catch control drift before the audit period
• Keep policies living documents with version history and annual review dates
• Train all employees on their role in maintaining SOC 2 controls
• Use the audit preparation timeline to avoid last-minute scrambling
• Treat each auditor exception as an improvement opportunity rather than a failure
