Discover every agent. Control every action. Verify every outcome.
AI agents don't fail only because of bad prompts. They fail when authorized agents take unauthorized actions. Nexus Shield intercepts the action, evaluates intent, controls capability, and creates verifiable evidence.
Competitive differentiator — VERIFY
Legacy gateways log prompts. Nexus Shield verifies actions — before/after state hashes, UNVERIFIED_ACTION detection, and downloadable evidence bundles auditors can reproduce.
