Authorize actions at the moment they happen.

RuntimeAuthorization describes a critical security layer between an autonomous system and the action it wants to perform. Instead of relying solely on static identity or permissions granted earlier, the runtime evaluates who is acting, what action is proposed, which resource is targeted, and whether that action should be permitted right now.

RuntimeAuthorization.com is unusually strong because the exact phrase is becoming a defined technical category rather than merely a descriptive concept. Current 2026 security work describes runtime authorization as the layer that evaluates an AI agent's specific action immediately before it reaches a protected resource. Microsoft similarly describes a shared authorization fabric that makes deterministic ALLOW, DENY, approval, or masking decisions before tool execution. :contentReference[oaicite:0]{index=0}
