Microsoft 365 security for credit unions

Credit unions answer to the NCUA, and most member data now lives in Microsoft 365. Siemserva by Senserva assesses your Microsoft 365, Entra ID, and Intune security against the controls examiners look at, ranks what to fix, and produces the evidence, so an exam is something you can walk into prepared.

Siemserva covers the Microsoft 365 side of your security program. It is not your entire NCUA program, your incident response plan, or legal advice.

The rules that apply

NCUA Part 748
Requires every federally insured credit union to maintain a written security program to protect member information and facilities.
Part 748 Appendix A (GLBA Safeguards)
Implements the Gramm-Leach-Bliley Act requirement to safeguard member information: access controls, encryption, monitoring, and ongoing risk assessment.
Part 748 Appendix B
Sets expectations for a response program for unauthorized access to member information, including member notification.
12 CFR 748.1(c): 72-hour notification
Requires notifying the NCUA within 72 hours of a reportable cyber incident, which depends on detecting and investigating incidents quickly.
NCUA examinations (ACET / FFIEC)
Examiners assess information security maturity, often with the Automated Cybersecurity Evaluation Toolbox, based on the FFIEC framework.

What Siemserva does for it

Safeguard access to member data
Evaluates MFA and Conditional Access across every user and app, finds gaps, exclusions, and legacy authentication. See Conditional Access analysis.
Keep systems patched
Reports missing patches and CVEs ranked by CISA KEV and EPSS. See CVE and patch management.
Limit privileged access
Surfaces standing Global Administrators, role assignments, and PIM eligibility so least privilege is demonstrable.
Monitor and detect
Confirms unified audit log health and analyzes sign-in, directory, and provisioning logs, supporting incident detection and the 72-hour rule. See log analysis.
Map to controls, with evidence
Every finding is ranked by Severity and mapped to compliance frameworks, with dated, examiner-ready reports. See compliance mapping.

It all comes from one connected model of your configuration, patching, and logs. See the unified security model.

Frequently asked questions

What cybersecurity rules apply to credit unions?

Federally insured credit unions follow NCUA Part 748, which requires a written security program. Appendix A implements the GLBA requirement to safeguard member information, Appendix B covers the response program for unauthorized access, and 12 CFR 748.1(c) requires notifying the NCUA within 72 hours of a reportable cyber incident. Examiners assess information security, often using the Automated Cybersecurity Evaluation Toolbox (ACET), based on the FFIEC framework.

How does Siemserva help with NCUA exams?

It assesses your Microsoft 365, Entra ID, and Intune security, MFA and Conditional Access, patching, privileged access, logging, and email protections, ranks the gaps, maps findings to controls, and produces dated, examiner-ready evidence. It covers the Microsoft 365 side of your security program, not the entire NCUA program.

Does it help with the 72-hour cyber incident notification rule?

Siemserva analyzes sign-in, audit, and directory logs and confirms logging is healthy, which supports detecting and investigating the reportable cyber incidents the 72-hour rule covers. It is a posture and detection-support tool, not a replacement for your incident response plan or reporting obligations.
