AI Agents Can Blur Who Is Acting Inside Corporate Browser Sessions

AI agents operating through an employee’s signed-in browser can use the access already available to that session, while ordinary application logs may not distinguish their actions from the employee’s. The concern is part of a broader browser-security gap as more business work and AI-assisted activity move into web apps. Keep Aware’s *State of Browser Security 2026* report describes agentic browsers that navigate sites, carry out multi-step workflows and interact with SaaS applications. When a person, an agent and page scripts share one authenticated session, security teams may have difficulty attributing actions to the right actor or applying data-loss prevention and threat-detection policies consistently (Keep Aware report).
