What Is AI Agent Runtime Security? The Complete Definition

AI agent runtime security is the discipline of monitoring, scoring, and controlling what AI agents actually do at execution time — at the operating system, network, and tool-call layers — independent of what they were configured or prompted to do. Here's the full definition, the layers it covers, and why it's the security category that didn't exist two years ago.

Behavioral Security for AI Agents: What It Is, Why It's Different, and Why Static Controls Fail

Behavioral security for AI agents is the practice of building a baseline of normal agent behavior, scoring every action against that baseline, and flagging divergence the moment it happens. Here's how it differs from every other AI security category — and why it's the only approach that catches what the agent actually does vs. what it claims to do.

What Is Behavioral Security? Definition, Examples, and Why It Matters for AI Agents

Behavioral security is the practice of establishing a baseline of normal activity for a system, then scoring every new action against that baseline. When applied to AI agents, it catches the attacks that static rules and prompt filters miss.

Meta's Rogue AI Agent Passed Every Identity Check. Then It Triggered a Sev-1.

An autonomous AI agent inside Meta posted flawed technical advice without human approval, exposing proprietary code and user data for two hours. Every identity check said the request was legitimate. Here's what the incident reveals about the four post-authentication gaps enterprise security hasn't closed.
