The Entra ID Misconfigurations Attackers Find First

Most Microsoft 365 breaches do not start with a sophisticated exploit. They start with a setting that was never reviewed. Legacy authentication protocols that bypass multi-factor authentication, service principals holding directory-wide write permissions, and guest accounts that were invited once and never removed all sit quietly in the tenant until someone enumerates them.
The pattern is consistent across the environments we audit. An attacker who lands a single valid credential does not need to escalate loudly. They look for the path of least resistance, and a misconfigured conditional access policy or an app registration with an expired but still trusted secret is exactly that.
EntraScan walks the same 45 indicators an attacker would probe, but it does so read-only and reports the findings with the exact remediation step for each one. The goal is not a longer report. The goal is a shorter list of things an attacker can actually use.
Start with the three categories that produce the most findings in practice: authentication baseline, privileged identity, and external access. Closing those usually moves the organizational risk score more than any other single effort.
