Best alternatives to CodeIntegrity in 2026

Regular software always does the same thing for the same input, which is why it's possible to test and trust it. AI agents don't work that way — the same prompt can lead to a different action depending on subtle context, and a cleverly worded message (a "prompt injection") can trick an agent into doing something it was never meant to do, like leaking data or taking a destructive action. CodeIntegrity exists to put a deterministic safety layer in front of that unpredictability, checking every agent action against strict rules before it's allowed to execute. CodeIntegrity builds runtime security controls for autonomous AI agents in production, enforcing security boundaries at the exact point of decision so an agent can't take an unsafe or unintended action even if it's been manipulated by a prompt injection. The team got attention for publicly demonstrating how easy it was to trick AI agents from several major vendors into leaking private information — including compromising the Notion note-taking app in under four hours, a stunt covered by The Economist — which is effectively their own proof of the problem they're now selling the fix for.
