How to prepare for a SOC 2 audit: scoping, trust services criteria, controls, evidence and the difference between Type I and Type II.
If enterprise customers keep sending security questionnaires, a SOC 2 report can shorten sales cycles and build trust. Here is how to get ready.
What SOC 2 is
SOC 2 is an attestation report issued by an independent CPA firm. It evaluates controls against the AICPA Trust Services Criteria: Security (always included), plus optional Availability, Processing Integrity, Confidentiality and Privacy.
Type I vs Type II
- Type I examines whether controls are suitably designed at a point in time.
- Type II examines whether controls operated effectively over a period, commonly several months to a year. Most customers ask for Type II.
Readiness roadmap
- Define scope. Systems, data, people and the criteria you will include.
- Run a gap assessment. Compare current controls with the criteria.
- Implement controls. Access management, MFA, change management, logging, vulnerability management, backups, vendor management and incident response.
- Write policies and procedures people actually follow.
- Collect evidence continuously: screenshots, logs, tickets and review records.
- Prepare for the auditor with a mock walkthrough.
Mistakes to avoid
- Scoping too broadly and creating unnecessary work.
- Writing policies that do not match reality.
- Collecting evidence only at audit time.
Important: SOC 2 reports are issued by independent auditors, not consultants. Our role is to get you ready. See our SOC 2 consulting services or try the compliance readiness benchmark.
