SOC 2 & ISO 27001
What is the difference between SOC 2 Type I and Type II?
Reviewed by the Privacy Horizon team · Last reviewed
Quick answer
A SOC 2 Type I report assesses whether your controls are suitably designed at a single point in time, while a Type II report tests whether those controls actually operated effectively over a period — commonly three to twelve months. Type II is more rigorous and is what most enterprise customers ultimately want; many companies do a Type I first to show progress, then a Type II over an observation window. Timeline and cost depend on your scope, how ready your controls are, and the audit period.

Type I: design at a point in time
A Type I report describes your controls and the auditor's opinion on whether they are suitably designed to meet the relevant Trust Services Criteria as of a specific date. It is faster to obtain and useful for demonstrating that you have the right controls in place, but it does not prove they work over time.
Type II: effectiveness over a period
A Type II report goes further: the auditor evaluates whether your controls operated effectively throughout an observation period, typically three to twelve months, by testing evidence sampled across that window. Because it shows sustained operation rather than a snapshot, Type II carries far more weight with customers and is usually the end goal.
Timeline and cost drivers
There is no single price or duration — both depend on your scope (which criteria and systems are in scope), how mature your controls already are, the length of the observation period, and your choice of auditor. A typical path is a readiness assessment to close gaps, followed by the audit; Type II then adds the observation window before the report can be issued.
Rather than quote a figure that may not fit your situation, we scope each engagement to your environment. Privacy Horizon helps you prepare efficiently so the audit itself is smoother and shorter.
Frequently asked questions
If customers need assurance quickly, a Type I demonstrates that your controls are well designed while you accumulate the operating history for a Type II. If you already operate mature controls, you can begin the Type II observation period directly. The right choice depends on customer pressure and your current readiness.
Readiness and remediation commonly take a few weeks to a few months depending on starting maturity; a Type II then requires an observation period (often three to twelve months) before the report is issued. A Type I can be completed much sooner.
SOC 2 Type II reports are typically renewed annually, since customers want a current report covering a recent, continuous period.
