TL;DR: Employee exit risk often begins weeks before HR notice, because job-search behaviour, client lookups, and unusual self-email patterns can reveal intent before files leave the organisation, according to Gurucul. The real failure is assuming resignation is the trigger, when the governance gap is behavioural blindness.

By the numbers:
- Only 20% have formal processes for offboarding and revoking API keys, and even fewer have procedures for rotating them.
- 92% of organisations expose NHIs to third parties, raising concerns about supply chain security.
Questions worth separating out
Q: How should organisations detect insider threats before an employee resigns?
A: Organisations should watch for sequences, not single events.
Q: Why do insider-risk programmes fail when they rely on HR notice dates?
A: They fail because HR notice arrives after the behaviour that matters has often already started.
Q: What behaviour patterns should trigger insider-risk review?
A: Look for combinations such as job-search activity, atypical client or repository access, repeated self-emailing, and movement toward personal storage.
Practitioner guidance
- Shift insider-risk triggers to behavioural sequences Escalate when job-site browsing, unusual client lookups, and personal-email activity appear in the same identity timeline, even if each event is individually allowed.
- Correlate logs by identity across systems Build a single investigation view that joins web, endpoint, data, and email activity for one user so analysts can see pre-notice behaviour as a sequence.
- Review sensitive access before HR notice Run periodic checks on users with access to client lists, source code, and strategic plans, because exit-related misuse often starts before formal resignation.

Gurucul's full blog covers the operational detail this post intentionally leaves for the source:
- The behavioural indicators Gurucul maps into its flight-risk watchlist logic across web, email, and data access signals.
- The mechanics of its unified risk scoring and how activity is normalised into a single identity timeline.
- The sequence of resume upload, client lookup, and self-email events used in the fictional Ken Winston scenario.
- The claimed investigation workflow that turns predicted intent into a decision-ready case for security or HR.

Behavioural blindness is the real insider-risk failure, not employee resignation. Legacy IRM often assumes the departure event is the risk trigger, but the risky behaviour usually starts earlier and looks ordinary in isolation. That means the governance model is built around HR latency instead of identity behaviour. The practitioner implication is that insider-risk programmes must treat pre-notice activity as first-class risk, not background noise.
A few things that frame the scale:
- 71% of NHIs are not rotated within recommended time frames, increasing the risk of compromise over time, according to Ultimate Guide to NHIs.
- 96% of organisations store secrets outside of secrets managers in vulnerable locations including code, config files, and CI/CD tools.
A question worth separating out:
Q: Who should be accountable when pre-notice exfiltration occurs?
A: Accountability should sit across security, IAM, HR, and the business owner of the data. HR supplies the lifecycle signal, IAM controls access, and security detects behavioural drift. If one team owns the problem alone, the organisation will usually discover the issue only after the data has already moved.
