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

+## Audit Preparation Timeline
+
+```yaml
+audit_prep_timeline:
+  12_months_before:
+    - Select auditor firm and sign engagement letter
+    - Perform gap assessment against TSC criteria
+    - Remediate identified control gaps
+    - Begin formal evidence collection cadence
+
+  6_months_before:
+    - Conduct internal readiness assessment
+    - Verify all controls are operating effectively
+    - Complete risk assessment and update risk register
+    - Ensure vendor assessments are current
+    - Test disaster recovery procedures
+
+  3_months_before:
+    - Run automated evidence collection and verify completeness
+    - Conduct access review and remediate findings
+    - Review and update all policies and procedures
+    - Perform vulnerability scan and penetration test
+    - Confirm all training records are current
+
+  1_month_before:
+    - Prepare evidence request list responses
+    - Organize evidence into auditor-friendly structure
+    - Brief key personnel on audit interviews
+    - Verify monitoring dashboards show healthy state
+    - Confirm incident response records are complete
+
+  during_audit:
+    - Designate audit liaison for request management
+    - Provide timely evidence and clarifications
+    - Track open auditor questions
+    - Escalate issues to control owners promptly
+
+  after_audit:
+    - Review draft report and provide management response
+    - Create remediation plan for any exceptions
+    - Communicate results to stakeholders
+    - Update controls and processes based on findings
+    - Begin next audit period evidence collection

 ## Best Practices
 
-- Continuous compliance monitoring
-- Annual risk assessments
-- Regular control testing
-- Documentation maintenance
+- 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
