TL;DR: Insider threat detection is increasingly about spotting compromised accounts, excessive downloads, third-party misuse, and privilege escalation before they become data loss or operational disruption, according to Zluri. The core lesson is that access visibility, review cadence, and event auditing must be tight enough to expose misuse before normal trust assumptions turn into breach paths.
Editorial analysis by NHI Mgmt Group, based on content published by Zluri: “Insider Threat Detection: Best Practices to Detect Them”.
By the numbers:
- 48% of organisations have seen an increase in insider attacks over the past year, according to Cybersecurity Insiders research cited by Zluri.
Key questions
Q: What breaks when insider threat monitoring is based only on alerts?
A: Monitoring breaks when alerts are treated as proof instead of signals.
Q: Why do third-party accounts need separate insider threat controls?
A: Third-party users often have legitimate but narrower access, different working hours, and less day-to-day oversight than employees.
Q: What are the signs that an insider threat programme is missing risky access?
A: Common signs include repeated failed logins, access to systems outside a user’s role, large downloads, sudden use of administrative privileges, and activity from unfamiliar locations or devices.
Practitioner guidance
- Correlate identity and behaviour signals Combine login context, file activity, and access history so that unusual location, time, or application use can be evaluated against the user’s normal pattern.
- Separate third-party access monitoring Track contractors and vendors with their own access policies, review cadence, and working-pattern baselines.
- Audit high-risk events continuously Retain and review logs for logins, file access, transfers, and configuration changes so investigators can reconstruct misuse and response teams can verify impact.
Bottom line: Insider threat detection is fundamentally an access governance problem because legitimate accounts can still produce data loss, disruption, and reputational harm.

Insider threat detection fails when organisations treat access as proof of trust. The article shows that compromised accounts, third-party misuse, and careless behaviour all begin with legitimate access, then diverge through abnormal use. That means the real problem is not authentication alone, but whether access governance can distinguish intent, scope, and time of use fast enough to matter.
A question worth separating out:
Q: How should teams respond when privilege escalation appears in access logs?
A: Treat privilege escalation as a governance failure, not just an alert. Validate whether the entitlement was approved, whether the role design allows that path, and whether the account should be restricted or removed immediately. Escalation often indicates that review, approval, or segmentation controls are not holding.
