The first wave of enterprise AI concern was straightforward. It was simply employees pasting sensitive data into public AI tools. Security teams responded with usage policies, domain blocks, and data loss prevention rules. That response made sense at the time.

It doesn't fit the problem anymore.

Shadow AI has shifted from a data leakage concern to an access control problem. The threat isn't about what employees type into AI tools. It's about which AI agents are running inside the organization, what enterprise systems they're connected to, and what actions they're authorized,or not, to take.

From passive tools to active actors

Employees and business units are building AI agents at a pace most security teams can't keep track of. Custom assistants, coding agents, workflow automations, and agentic applications are being created across departments with some in sanctioned platforms, but many through browser extensions, SaaS-native features, developer tools, MCP servers, endpoint-based agents, and custom scripts. Many start as quick experiments. Some become embedded in critical business processes within days.
