TL;DR: GCC High supports six of the eleven NIST 800-171 identification and authentication controls by default, but the remaining five, including multifactor authentication and inactivity handling, require explicit tenant configuration and evidence, according to Secureframe. The practical issue is not platform capability alone, but proving that identity enforcement, documentation, and assessor-ready configuration are actually in place.

By the numbers:
- Only 20% have formal processes for offboarding and revoking API keys, and even fewer have procedures for rotating them.
- 91.6% of secrets remain valid five days after the targeted organisation is notified, showing a critical gap in remediation procedures.
- 90% of IT leaders say properly managing NHIs is essential for a successful zero-trust implementation.
Questions worth separating out
Q: What breaks when MFA is registered but not enforced in GCC High?
A: Registration without enforcement leaves a gap between policy intent and actual access control.
A: They complicate the control family because they are non-human identities that still need unique identifiers, documented purpose, and restricted authentication paths.
Q: How do security teams know whether inactivity controls are actually working?
A: They should be able to show a documented inactivity threshold, the workflow used to detect dormant identifiers, and the records proving accounts were disabled or reviewed on schedule.
Practitioner guidance
- Verify MFA enforcement, not just MFA registration Check Conditional Access policies, allowed methods, break-glass exceptions, and local privileged access paths to confirm that required accounts must actually satisfy MFA in GCC High.
- Document every in-scope identity type Map users, processes, devices, service principals, managed identities, guest accounts, and break-glass accounts to the control family so assessors can see how each is uniquely identified and authenticated.
- Set a clear inactivity threshold and prove it runs Define the number of days after which an identifier is disabled, then keep exports or review records that show the process is executed consistently.

Identity assurance is the control family that makes every other CMMC claim believable. If the environment cannot prove who or what authenticated, access control and audit evidence become less trustworthy. GCC High may supply the identity substrate, but the organisation still owns enforcement, exceptions, and lifecycle documentation. Practitioners should treat assurance as a prerequisite, not an outcome.
A few things that frame the scale:
- 91.6% of secrets remain valid five days after the targeted organisation is notified, showing a critical gap in remediation procedures, according to Ultimate Guide to NHIs.
- 79% of organisations have experienced secrets leaks, with 77% of these incidents resulting in tangible damage.
A question worth separating out:
Q: Who is accountable when GCC High identity controls fail an assessment?
A: Accountability sits with the organisation using the tenant, not with the platform provider. Microsoft may supply identity capabilities, but the tenant owner must configure policies, manage exceptions, retain evidence, and demonstrate that the controls operate as described in the SSP and assessment boundary.
