What is the GSO Recommendations library?
The Overe GSO Recommendations library is a publicly accessible reference of Microsoft 365 security recommendations, maintained by the Overe team as part of our Guided Security Operations (GSO) approach.
Each recommendation covers a specific Microsoft 365 risk: what it is, why it matters, what happens if it is exploited, when it is expected or acceptable, and how to remediate it safely.
What does it cover?
The library includes recommendations across the key Microsoft 365 risk areas Overe works with:
Conditional Access gaps and policy drift
Entra ID identity risks (admin roles, risky MFA settings, privileged accounts)
OAuth app exposure and service principal abuse
Token theft and device code phishing
Anomalous activity patterns that indicate ransomware preparation or data destruction
Microsoft 365 hardening checks and CIS benchmark alignment
How to use it
Each recommendation page includes:
Why this risk matters: context on the threat and its real-world impact
What happens if abused: what an attacker can do with this exposure
When it is expected or acceptable: common exceptions and false positive scenarios
Checks to perform before taking action: pre-remediation steps to avoid disruption
Safe remediation steps: how to fix it without impacting users
Supporting documentation: Microsoft and third-party references
Relationship to Overe findings
When Overe surfaces a finding in your tenant assessment, the recommendation library provides the detailed guidance behind that finding. Where Overe shows you what is wrong, the library explains why it matters and how to fix it safely.
The library is updated as new risks emerge and as Overe adds new detection and assessment capabilities.
