SOC 2 Audit Process Overview
The SOC 2 audit process involves preparing your organization, implementing controls, operating them over time (for Type II), and undergoing examination by a CPA firm. Understanding each phase helps you plan resources and set realistic expectations.
Timeline Summary
Type I: 2-4 months total (readiness + audit)
Type II: 9-15 months total (readiness + 6-12 month observation + audit)
Phase 1: Scoping & Planning (2-4 Weeks)
Before any audit work begins, you need to define what's being examined.
Define Your Scope
Services: Which products/services will be covered?
Systems: What infrastructure, applications, and tools support those services?
Trust Services Criteria: Which criteria apply? (Security is required; others optional)
Report Type: Type I or Type II?
Observation Period: For Type II, what period? (typically 6-12 months)
Select Your Auditor
SOC 2 audits must be performed by a licensed CPA firm. Selection criteria include:
Experience with your industry and technology stack
Reputation and references
Pricing and timeline
Communication style and accessibility
Establish Project Team
Executive sponsor
Project lead (often InfoSec or Compliance)
Technical representatives (Engineering, IT, DevOps)
Process owners (HR, Finance, Operations)
Deliverables: Scope document, auditor engagement letter, project plan
Phase 2: Readiness Assessment (4-8 Weeks)
A readiness assessment (gap analysis) compares your current state to SOC 2 requirements.
What's Assessed
Existing policies and procedures
Technical controls (access, encryption, monitoring)
Administrative controls (HR processes, vendor management)
Physical controls (if applicable)
Evidence collection capabilities
Gap Analysis Output
The assessment produces:
Control mapping to Trust Services Criteria
Gap identification (what's missing or weak)
Risk prioritization
Remediation roadmap with effort estimates
Readiness Options
Self-assessment: Internal team using templates/frameworks
Consultant-led: Expert assessment with recommendations
Auditor-led: Pre-audit by your CPA firm (watch for independence issues)
Deliverables: Gap analysis report, remediation plan, updated timeline
Phase 3: Remediation (4-12 Weeks)
Close the gaps identified in your readiness assessment.
Common Remediation Activities
Documentation: Create/update policies, procedures, standards
Access Controls: Implement MFA, access reviews, least privilege
Monitoring: Deploy logging, alerting, SIEM
Change Management: Formalize change control processes
Incident Response: Document and test IR procedures
Vendor Management: Assess and document vendor security
Evidence Collection System
Critical for Type II: establish systems to automatically collect evidence:
Access review records
Change tickets and approvals
Training completion records
Incident tickets
Vulnerability scan results
