Cisco Just Built Zero Trust for AI Agents. Here's Why That Matters.

Traditional Zero Trust was built for humans. A person authenticates, gets a scoped token, makes a few requests per session, and eventually logs out. The security model assumes a user who reads screens, clicks buttons, and operates at human speed. AI agents don't work like that. An autonomous agent running a multi-step task might hit 40 different APIs, spawn sub-agents, access databases it's never touched before, and do all of it in under a minute. The security model that works for a human clicking through a dashboard completely falls apart when the "user" is an LLM making thousands of decisions per second. At RSA Conference 2026 on April 1, Cisco unveiled a Zero Trust architecture built specifically for this problem -- real-time policy enforcement and anomaly detection designed for autonomous AI agents and multi-agent systems. Why Existing Security Models Break Here's the fundamental mismatch. Traditional Zero Trust gives you a token at authentication time with a fixed set of permissio
