What does EVE CoreGuard do?
EVE CoreGuard is a pre-execution governance runtime for regulated AI. It sits between an AI agent and the systems it acts on, checking every proposed action against a fixed policy before anything runs. If the action can't be defended, it's blocked. If it's allowed, the runtime issues a signed decision record that a third party can verify later.
What makes it stand out is that the enforcement path is fully deterministic. The verdict comes from a rule engine with 15 charter rules and 5 immutable red lines, not from a language model. That means a prompt can't talk its way past a guardrail. Every decision is signed with ECDSA P-384, and the records are hash-chained and replayable offline. The page walks through a live example: a $50,000 wire approved with a single-use certificate runs once; when the same certificate is reused with one field changed, the runtime denies it before the payment connector is ever called.
This is for organizations that can't afford to check the logs later — banks, healthcare, and other regulated businesses. It's useful for AI platform teams that need to prove compliance, for security teams that want to stop destructive agents, and for anyone who needs an audit trail that shows not just what an AI did, but what it was allowed to do.
