TenantGuard

What it does

TenantGuard connects to your M365 tenant via the Microsoft Graph API and runs 7 security checks — MFA gaps, legacy auth, mail forwarding, inactive admins, guest accounts, audit logging, and Secure Score. Find issues and fix them with one click. First scan free.

Scan your Microsoft 365 tenant for security risks in minutes. Find MFA gaps, legacy auth, mail forwarding, inactive admins, and more. First scan free.

TenantGuard scans your entire M365 tenant in minutes — surfacing misconfigurations, exposed accounts, and security gaps before attackers do. Sign in with your Microsoft admin account. We request read-only Graph API permissions with admin consent — no passwords stored. TenantGuard runs 18 parallel security checks across your users, policies, Conditional Access, DNS records, OAuth grants, and sign-in risk in about two minutes. Each issue comes with a one-click remediation that applies the fix directly via Microsoft Graph — no PowerShell required. Every check maps to a real attack vector used in M365 breaches. Identifies global admins without multi-factor authentication — the #1 cause of M365…from tenantguard.io
