Three Companies Just Converged on Intent-Based AI Agent Security. None of Them Can Verify Identity.

RSA Conference 2026 just wrapped and the theme is unmistakable: intent-based security is the new paradigm for AI agents. Three separate announcements this week landed on the same thesis: Token Security: Identity as the Control Plane Token Security unveiled intent-based AI agent security that governs autonomous agents by aligning permissions with intended purpose.
