insider threat vs exit triage

both involve a departing employee — but insider threat is sustained access-anomaly and exfiltration; disgruntled exit is last-day endpoint sabotage and deletion bursts.

editorial overlap

lean toward…

disambiguation signals derived from case-type descriptions and common practitioner confusion points.

lean toward insider threat if you see…

  • gradual data-access spike or peer-group outlier over days or weeks before departure
  • cloud-share or USB exfil patterns flagged by DLP — not just last-day wipe artifacts
  • after-hours browsing or copy-paste bursts on sensitive repositories

lean toward exit triage if you see…

  • mass rename, secure deletion, or registry-key deletion burst on final workday
  • scheduled-task or service deletion logged hours before badge deactivation
  • browser or PowerShell history clearing — endpoint sabotage, not long-run exfil scoring
