TL;DR: Data security teams are seeing insider threat detection move from a niche capability to a core DSPM requirement, according to ArexData. DSPM now has to surface misuse early while preserving the evidence and approval chain needed for governed remediation.
Editorial analysis by NHI Mgmt Group, based on content published by ArexData: “Data Security Trends for 2026”.
By the numbers:
- Organisations that rely heavily on static credentials reported a 20-percentage-point increase in security incidents compared with those with low reliance, according to the 2026 Infrastructure Identity Survey.
Key questions
Q: Why does valid access create insider risk in DSPM?
A: Valid access creates insider risk in DSPM because a legitimate user, service account, or analyst can still read, copy, or move sensitive data once permissions grant reach.
Q: How should teams prove what happened after a data exposure?
A: Teams should prove what happened by preserving logs, endpoint telemetry, cloud audit trails, data classification records, and the access path from source to sink.
Q: Why do insider threat indicators matter for security teams?
A: Insider threat indicators matter because they can show misuse of legitimate access before data loss, sabotage or fraud occurs.
Practitioner guidance
- Tie DSPM alerts to identity context Correlate data access with user, service account and entitlement data so unusual handling can be distinguished from normal operations.
- Define evidence retention for every remediation path Keep logs that show what was exposed, who reviewed it, what action was taken and whether the action was approved.
- Segment automated from human-approved remediation Allow automation to triage and prioritise issues, but require human approval before any irreversible deletion or restriction action.
Bottom line: DSPM is expanding from data discovery into identity-aware detection, evidence retention and governed remediation.

Insider threat detection is becoming a core DSPM control, not an add-on. Data security teams can no longer treat exposure discovery as sufficient, because misuse often happens through valid access paths. The governance question is whether the platform can tie data events back to identity, entitlement and behaviour. Practitioners should treat detection quality as a first-class requirement in DSPM selection.
A few things that frame the scale:
- Business leaders plan to spend $124 million on average on AI in 2026, and 91% say data security and risk will shape their AI strategy.
A question worth separating out:
Q: What is the best way to govern human-in-the-loop remediation?
A: The best way to govern human-in-the-loop remediation is to require clear approval boundaries, logged recommendations, and a human final decision for changes that affect production or security controls. Use RBAC or PAM for who may approve, JIT for elevated actions, and immutable audit logs to record overrides, rollbacks, and exceptions.
