What this check verifies

No Conditional Access policy was found that enforces MFA for all users across all applications. Indicates a fundamental gap in tenant-wide MFA coverage

Why it matters

Without tenant-wide MFA, password-only sign-ins work for every user and every app. Phishing, credential stuffing, and spray attacks succeed at much higher rates

How to fix it

Create CA policy requiring MFA for all users; deploy in report-only, validate, then enforce

Siemserva flags every tenant where this check fails and, with Senserva Trustworthy AI remediation, can propose a validated fix you approve before it applies.
