The UK NCSC Cyber Assessment Framework is an outcome-based framework for operators of essential services and the public sector. Its identity, access-control, and security-monitoring objectives align strongly with Microsoft 365 and Entra ID findings.

NCSC CAF and Microsoft 365: common questions

Does NCSC CAF apply to Microsoft 365?

NCSC Cyber Assessment Framework (CAF) does not name Microsoft 365 specifically, but its identity, access-control, and logging requirements are met (or missed) in your Microsoft 365 and Entra ID configuration. That is where Siemserva checks provide the evidence.

How does Siemserva map to NCSC CAF?

Siemserva runs 210+ Microsoft 365 and Entra ID checks across the areas NCSC CAF emphasizes, multi-factor authentication, Conditional Access, privileged access, and logging, ranks the gaps by Severity, and produces audit-ready evidence. It is evidence, not an official mapping or certification.

Is this an official NCSC CAF certification?

No. Senserva is not an assessor and issues no certifications. It provides the configuration evidence, Severity ranking, and remediation that make an assessment defensible. Confirm requirements with your assessor or regulator.
