Hey Product Hunt! 👋 I'm Jonathan, the maker of TenantGuard. I built this after spending way too long manually checking Microsoft 365 tenants for security misconfigurations — navigating between a dozen different admin portals just to answer "are all our admins using MFA?" It was slow, inconsistent, and easy to forget entirely. TenantGuard runs 7 security checks on your M365 tenant in about 2 minutes via the Microsoft Graph API and lets you fix most issues in one click — no PowerShell, no scripts, no jumping between portals. The first scan is completely free. Pro ($29/month) adds weekly automated scans, email alerts when new issues appear, scan history, and PDF compliance reports. Happy to answer any questions about M365 security, the build, or anything else. Would love your honest feedback — what checks would you want to see added?
