TenantLens

TenantLens is a free, open-source scanner that reads the configuration of your Microsoft 365, Entra ID, Exchange Online and Azure tenant and reports security gaps. It is read-only by design: it refuses any request that would change your tenant.

  • 96 read-only checks across Entra ID, Conditional Access, apps and consent, Exchange Online and Azure
  • Runs locally. Your tenant data stays on your machine.
  • Reports you can share with your team
