NIST Cybersecurity Framework (CSF) and Microsoft 365

What NIST CSF is

The NIST Cybersecurity Framework organizes security into functions, Identify, Protect, Detect, Respond, Recover, and Govern. Its Protect and Detect functions map cleanly onto Microsoft 365 multi-factor authentication, Conditional Access, and logging findings.

How Siemserva maps to NIST CSF

NIST CSF asks for strong identity, access control, and monitoring. Siemserva evidences those areas with the checks below, each ranked by Severity and checked against your own tenant:

• Multi-factor authentication (42 checks)

  Auth User Not MFA RegisteredAuth Microsoft Authenticator Authentication Method In Use But Not Allowed By UserAuth Password Authentication Method In Use But Not Allowed By Senserva Security ManagerAuth Passwordless Microsoft Authenticator Authentication Method In Use But Not Allowed By UserAuth Require Passwordless But Its Not Used By UserAuth Software Oath Authentication Method In Use But Not Allowed By User

• Conditional Access (60 checks)

• Logging and audit (43 checks)

Evidence NIST CSF in your own Microsoft 365

Siemserva by Senserva runs the identity, access, privileged-access, and logging checks above, and 650+ others, against your own tenant: it shows where you meet or miss each requirement, ranks the gaps by Severity, and produces audit-ready evidence and validated fixes to close them.
