SOC 2 Explained: Type I vs Type II, and What Auditors Expect
SOC 2 has become the price of doing business with enterprise customers. Here is what it is, the difference between Type I and Type II, the Trust Services Criteria, and how to get through it smoothly.
Key takeaways
- SOC 2 is an attestation by an independent CPA that your controls meet the AICPA Trust Services Criteria.
- Type I checks control design at a point in time; Type II checks that controls operated effectively over a period.
- Enterprise buyers usually want Type II — it is stronger evidence.
- A consultant prepares you and manages the process; the CPA firm issues the actual report.
What SOC 2 is
SOC 2 is a reporting framework from the AICPA that lets a service organisation demonstrate it manages customer data securely. An independent CPA firm examines your controls against the Trust Services Criteria and issues a report your customers can rely on during their vendor reviews.
For SaaS and technology companies, it has effectively become the entry ticket to enterprise deals — the report answers the security question before it stalls a sale.
Type I vs Type II
A SOC 2 Type I report assesses whether your controls are suitably designed at a single point in time. It is faster to achieve and useful as a first milestone.
A SOC 2 Type II report goes further: it assesses whether those controls actually operated effectively over a period, usually three to twelve months. Because it proves controls work over time, it is the report most enterprise customers expect.
The five Trust Services Criteria
SOC 2 is built on five criteria: Security (mandatory), Availability, Processing Integrity, Confidentiality and Privacy. Most organisations scope Security plus the criteria relevant to their promises to customers. Part of getting ready is choosing the right criteria — over-scoping wastes effort, under-scoping undermines the report.
Getting audit-ready
Readiness means a gap assessment, designing and implementing controls your team can operate, producing policies and evidence, and running the penetration testing auditors expect. A consultant coordinates the whole thing and manages the independent CPA audit.
To be clear on roles: the CPA firm issues the SOC 2 report. Aesparrow prepares you, builds the controls, and runs the process — we are a readiness partner, not the attesting auditor.
