AI data governance for insider threat detection - genuinely useful or just expensive noise
Been going down a rabbit hole on this lately after the 2026 DTEX Insider Threat Report dropped, showing average insider incident costs hitting $19.5M. The negligence piece is what gets me - shadow AI and accidental misuse are, consistently showing up as the dominant risk drivers, outpacing malicious actors as the primary vector. From a GRC angle that's a real problem because your traditional rule-based controls just aren't built to catch that kind of drift. You can't write a policy rule for "employee pasted sensitive data into a gen AI tool they found on Product, Hunt." We've been looking at a few platforms and the behavioral analytics side is genuinely impressive when it's tuned properly. The anomaly correlation across identity and data access signals has actually reduced the triage noise our team deals with. But I keep hitting the same wall - only 37% of orgs apparently have formal AI governance policies despite the majority already deploying gen AI in, security contexts, and without that integration into your broader Zero Trust and access governance model it really does just become another monitoring layer that nobody acts on. The part I'm still working through is the cost justification. For mid-size environments the subscription costs can get uncomfortable fast, and if your SOC doesn't have the capacity, to action the alerts properly you've basically paid a lot of money to document problems you can't fix. The newer predictive capabilities are interesting though - early intervention weeks before a breach actually occurs is a different ROI conversation than pure detection and reporting. Microsoft Purview extending DLP to AI agents is worth watching from a compliance standpoint since it at least fits into frameworks we're already operating in. But I'm curious whether teams are finding these platforms actually move the needle on prevention, or if most of the value is still sitting on the detection and reporting side. Anyone here deployed something like this and actually got it to the point where it's reducing incident costs rather than just surfacing them?
