NIST SP 800-53 and Microsoft 365

The US federal control catalog; already in Senserva's reference set. Siemserva by Senserva maps 252+ Microsoft 365 and Entra ID checks to the areas NIST 800-53 emphasizes, so a scan of your tenant doubles as evidence.

What NIST 800-53 is

NIST SP 800-53 is the US federal control catalog and a global reference for security control frameworks. Its Access Control (AC), Identification and Authentication (IA), and Audit and Accountability (AU) families map directly to Entra ID identity and Microsoft 365 logging findings, and every Senserva check already carries its 800-53 mapping.

Official reference: NIST SP 800-53

How Siemserva maps to NIST 800-53

NIST 800-53 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:

Identity and access management (60 checks)
At Risk With High Risk User Break Glass Account Disabled User Break Glass Account Is Not Highly Privileged User Break Glass Account Last Password Change User Break Glass User Not Enabled User High Risk User
Conditional Access (60 checks)
Conditional Access Admin Portal Missing MFA Conditional Access Break Glass Account Covered By Policy Conditional Access Group Critical Coverage Gap Conditional Access MFA Policy Bypassed Conditional Access User Critical Coverage Gap Conditional Access Block Legacy Exchange Active Sync Not Found
Privileged access (PIM) (34 checks)
PIM Alerts No MFA On Activation Alert PIM Policy Expiration Required PIM Policy Missing For User Role Ai Administrator Assigned Role Standing High Privilege Assignment PIM Alerts License Suspended
Multi-factor authentication (42 checks)
Auth User Not MFA Registered Auth Microsoft Authenticator Authentication Method In Use But Not Allowed By User Auth Password Authentication Method In Use But Not Allowed By Senserva Security Manager Auth Passwordless Microsoft Authenticator Authentication Method In Use But Not Allowed By User Auth Require Passwordless But Its Not Used By User Auth Software Oath Authentication Method In Use But Not Allowed By User
Logging and audit (43 checks)

NIST 800-53 and Microsoft 365: common questions

Does NIST 800-53 apply to Microsoft 365?

NIST SP 800-53 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 NIST 800-53?

Siemserva runs 252+ Microsoft 365 and Entra ID checks across the areas NIST 800-53 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 NIST 800-53 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.
