Starting SOC 2 Type 2 after Type 1

TL;DR. Treat Type 1 as the starting gun for operating effectiveness. Keep control owners, calendared reviews, and evidence pulls running through the entire window. Shorten or lengthen the period based on buyer pressure and how stable your controls already are.

TYPE 2 WINDOW · EMPTY

Observation window not started. Keep owners and weekly evidence rhythm running the day Type 1 closes.

On this page

The day after Type 1

Do not dissolve the compliance channel. Keep the same owners, the same review calendar, and the same evidence pack structure. Type 2 is mostly whether you kept doing the work.

Picking window length

Changing people, IdP, or cloud accounts mid-window is possible but creates explanation load—plan migrations deliberately.

Questions founders ask

Can the Type 2 window start before Type 1 is issued?

Discuss with your auditor—operating periods can be planned deliberately.

What if we fail a control mid-window?

Remediate, document, and discuss; do not hide it.

Do policies need rewriting for Type 2?

Only if they drifted from practice—align paper to reality.
