When people hear the phrase "insider threat," the conversation almost always turns toward malicious employees. We picture someone stealing intellectual property, exfiltrating customer data, or sabotaging systems before walking out the door. Those scenarios certainly exist, but I have come to believe they represent only a small part of the problem. The real challenge is understanding the conditions that create insider risk in the first place.
From a cyber threat intelligence perspective, insider threat is less about people and far more about opportunity. Every organization contains trusted identities, privileged access, critical business processes, and assumptions that quietly become embedded in daily operations. An adversary rarely cares whether access comes from an employee, contractor, compromised account, or autonomous AI agent. They care about leverage, and the easiest path is almost always through something the organization already trusts.
That realization changes the conversation. Instead of asking how we can monitor employees more effectively, perhaps we should ask which business capabilities would create the greatest financial, operational, or reputational impact if they were manipulated by someone with legitimate access. Which identities can approve payments, alter production systems, or access sensitive information? Which processes rely on inherited privileges or a level of trust that has never been questioned?
The organizations that consistently reduce insider risk are rarely the ones collecting the most telemetry. They are the ones that understand where trust intersects with business dependency and where excessive privilege creates disproportionate risk. They use cyber threat intelligence to identify how adversaries are most likely to exploit those relationships, then redesign workflows so that no single trusted identity can create outsized business impact without additional validation or oversight.
This becomes even more important as agentic AI enters the enterprise. Autonomous systems will increasingly make decisions and execute actions on behalf of people. If we continue defining insider threat around humans alone, we risk overlooking the broader challenge of trusted execution.
Perhaps the future of insider threat is not really about insiders at all. It is about understanding trust as an attack surface. CTI helps identify where adversaries will exploit that trust, while business impact analysis tells us where failure would hurt the most. Together, they transform insider threat from a reactive monitoring function into a strategic capability that strengthens resilience before an incident ever occurs.
Maybe the question leaders should be asking is no longer, "Who do we trust?" Perhaps the better question is, "Where have we placed so much trust that losing it would fundamentally change how our business operates?"

Samantha S.: Agreed! Went to an awesome talk by Jim Simpson at Hack Thursday last month about AI agents and insider risk.
Luis P.: I agree James. Insider threats may also emerge from excessive privileges, not only from insufficient controls. That's why designing the environment in which actions take place can be a complementary approach. Sometimes, making the desired action the most natural one is as important as adding another control.
