Overview
Atlant 365 Auditor scans your entire M365 tenant in minutes and surfaces every misconfiguration in a clear, actionable report.
Use the Microsoft 365 security audit checklist to review effective controls, evidence and exceptions alongside the tool output.
Most Microsoft 365 tenants ship with insecure defaults - overshared mailboxes, disabled audit logs, legacy authentication still enabled, and MFA gaps across admin accounts. Finding these issues manually means clicking through dozens of admin portals.
