RCA / SENTINELONE / POLICY
Prevention policy
investigation.
A structured method for understanding why a SentinelOne prevention control did or did not take effect on an endpoint.
Find the effective policy
Confirm the endpoint group, policy assignment and effective configuration instead of relying on an assumed policy.
Check exceptions
Review exclusions and their scope carefully; do not weaken prevention controls without evidence.
Validate behavior
Compare policy state with the observed process, event and detection telemetry.

Root-cause rule
Before changing exclusions or prevention settings, prove the effective policy and reproduce the behavior. A policy change is remediation only when it addresses the demonstrated cause without unnecessarily reducing endpoint protection.
