What is the difference between SOC 2 Type I and Type II?

More context

The distinction is design versus operation. A Type I report answers a narrower question: on the assessment date, are the right controls in place and suitably designed to meet the applicable Trust Services Criteria? It says nothing about whether those controls actually functioned day after day. A well-designed control that is never enforced would still pass Type I, which is why the report is often treated as a milestone rather than a destination.

Type II raises the bar by testing operating effectiveness across the whole period, which means an auditor gathers evidence that each control ran as intended over months, not one afternoon. Because of that, prospective enterprise customers and procurement teams tend to insist on a Type II report before trusting a vendor with regulated data, and many treat a Type I as merely the first step on the way to it.
