Interactive AI Security
AI Acts In Milliseconds, Your Security Has To Keep Up
Traditional security matches signatures and checks access after the fact. Defiance AI™ reads the intent behind every prompt, response and agent action as it happens, and stops the harmful ones.
A Unified Security Solution
Defiance AI™ secures your entire agentic plane, ensuring risk, compliance, and humans are protected. The solution grows with your AI maturity and learns in real time, so no breach is too novel to contain.
Monitor All AI
Maps every AI client, agent and data path. Shadow AI stops being invisible.
Confirm Every Intent
Checks the intent of every exchange and the identity behind it.
Prove Every Decision
Turns written policy into live rules, backed by an immutable audit trail.
Stop Bad Intent Inline
Blocks rogue behavior the moment it happens. Routine work passes.
Every Detection Makes Every Deployment Smarter
THE SELF-IMPROVING INTENT ENGINE
Defiance AI™ learns how AI goes rogue, then shares each new detection with every deployment. Every client is protected by what the engine learns anywhere.
Visibility
Discover every endpoint, agent and data path, sanctioned or not.
Detection
Classify the intent and risk behind every prompt, response and tool call.
Response
Enforce policy inline. Routine work passes untouched.
Learning
Every new detection updates protection across every deployment.
Covering All The Risks In Real Time
Go beyond traditional cyber security. Defiance AI™ reads intent, so it catches the risks that look like ordinary work. No threat is too novel.
