Atlant 365 Auditor
v1.0.0WindowsFree
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. Atlant 365 Auditor scans your entire M365 tenant in minutes and surfaces every misconfiguration in a clear, actionable report.
