What is SOC 2, and who needs it?

Quick answer

SOC 2 is an attestation framework from the AICPA that proves you meet the industry standard for managing and protecting customer data. An independent auditor examines your controls against the Trust Services Criteria (security, availability, processing integrity, confidentiality, and privacy) and issues a report your customers can rely on. If you're a B2B SaaS company selling to US enterprises, SOC 2 is usually the first certification procurement asks for.

Type I versus Type II

Type I describes your controls at a point in time: cheaper and faster, but weaker evidence.
Type II tests whether the controls operated effectively over a period, typically 3 to 12 months. This is what serious buyers expect.

Because Type II covers a period, you can't cram for it. Evidence has to exist continuously across the audit window, which is why teams pair SOC 2 with continuous control monitoring rather than annual screenshot hunts.

Who needs SOC 2

SaaS and cloud vendors selling to US enterprises or US-influenced buyers.
Outsourcing providers handling customer data (support, billing, analytics).
Startups whose deals stall in security review; a SOC 2 report often unblocks them.

European buyers more often ask for ISO 27001; the two overlap heavily, and many companies run both from one cross-mapped control set.

What the audit covers

Expect scrutiny of access control and MFA, change management, incident response, vendor management, backup and recovery, and risk assessment. The auditor samples evidence across the period, so timestamped, tamper-evident records are what make the audit smooth; see how OptiTech supports SOC 2.
