WARNING: Your Microsoft 365 Environment May Not be Secure

THE HIDDEN RISK IN MICROSOFT 365: TENANT MISCONFIGURATIONS

Misconfiguration—not malware—is the leading cause of Microsoft 365 security incidents.


This whitepaper explores:

  • The most common Microsoft 365 tenant misconfigurations
  • Why these issues persist despite built-in security tools
  • How a Security Posture Assessment and continuous monitoring help identify and reduce risk before attackers exploit it

59% OF MICROSOFT 365 TENANTS STILL DON'T ENFORCE MFA - LEAVING 99.9% OF PREVENTABLE COMPROMISES WIDE OPEN

LET US REPORT ON YOUR MICROSOFT TENANT SECURITY

Microsoft 365 is the backbone of modern work—but visibility gaps, misconfigurations, and identity‑based attacks often go unnoticed without continuous monitoring.

Common impacts include:

  • Account takeover and identity compromise
  • Data leakage and unauthorized access
  • Email and collaboration security gaps
  • Compliance and audit failures

According to Egress’ “Outbound Email: Microsoft 365’s Security Blind Spot” report, based on independent research by Arlington Research, 85% of organizations using Microsoft 365 experienced an email data breach within a 12‑month period.

This doesn’t mean Microsoft 365 is broken—it means security requires ongoing oversight.
