SOC 2 Compliance: A Plain-English Guide
SOC 2 is the report enterprise buyers ask for before they trust you with their data. Developed by the AICPA, it is an independent audit of how a service organization manages and protects customer information. For SaaS and cloud companies, it has shifted from a competitive edge to a cost of doing business: no SOC 2, no deal with serious customers.

For SaaS and cloud companies, it has shifted from a competitive edge to a cost of doing business: no SOC 2, no deal with serious customers.
What makes SOC 2 different from a checklist certification is that it is tailored to your operations and signed by an independent auditor. It does not ask whether you ticked a box. It asks whether your controls actually work.
The five Trust Services Criteria
A SOC 2 audit measures your controls against up to five criteria. Only one is mandatory; the rest you include based on what you actually do for customers.
The two report types
| Type I | Type II | |
|---|---|---|
| What it tests | Control design as of a point in time | Control design and operating effectiveness over a period |
| Time frame | A specific date | Typically 3 to 12 months |
| Proves | The right controls exist | The controls actually worked, consistently |
| Best for | Starting the SOC 2 journey | The expected standard for enterprise buyers |
SOC 2 comes in two flavors, and the difference matters when a buyer asks which one you have. One proves your controls exist. The other proves they have been working.
[[INSIGHT: A Type I report says “we have a lock on the door.” A Type II report says “we have a lock, and here is the log proving it stayed locked for the last nine months.” Enterprise buyers stopped accepting the first answer years ago.]]
- SOC 2 is an AICPA framework that audits how you protect customer data.
- It measures controls against five Trust Services Criteria; security is the only mandatory one.
- Type I tests control design at a point in time; Type II tests effectiveness over months.
- Only a licensed CPA firm can perform the audit.
- SOC 2 does not directly certify compliance with laws like GDPR or CCPA.
Frequently asked questions
What is SOC 2 compliance?
SOC 2 is an AICPA auditing framework that evaluates how a service organization manages and protects customer data against five Trust Services Criteria. A SOC 2 report is the independent attestation of those controls.
What are the five Trust Services Criteria?
Security, availability, processing integrity, confidentiality, and privacy. Security is mandatory in every report; the other four are included based on the services you provide.
What is the difference between SOC 2 Type I and Type II?
Type I evaluates whether controls are designed appropriately at a point in time. Type II evaluates both design and operating effectiveness over a period, typically 3 to 12 months, and is the standard enterprise buyers expect.
Who can perform a SOC 2 audit?
Only an independent, licensed CPA firm that is registered with the appropriate state boards and maintains active AICPA membership. The attestation follows AICPA standards (SSAE No. 18).
