Agentic AI, or AI systems that can act autonomously on behalf of users, is emerging as security's next major vulnerability because it operates with limited oversight while having significant access to sensitive systems and data. These AI agents can make decisions and take actions without explicit human approval in each instance, creating a new attack surface that organizations aren't adequately prepared to defend. Security teams need to develop new frameworks to monitor and control these autonomous systems before they become the next preferred entry point for cyber attackers.
