EVE AI Core
The Infrastructure of No.
Autonomous, tool-using agents expand the attack surface: prompt injection, data exfiltration, unsafe tool calls. Guardrails estimate and fail open. EVE AI Core is a deterministic gate that fails closed — every action is authorized before it runs.
A probabilistic guardrail is a second model estimating whether an output looks unsafe after it is generated — and when it is unsure, it tends to fail open. For an autonomous agent that can call tools, move data, and take actions, “usually catches it” is not a boundary. The boundary has to be a deterministic decision, made before the action executes, that fails closed.
When the gate cannot confidently permit an action, it denies. Deterministic, not probabilistic — the opposite of a guardrail that fails open.
Tools and agents must be registered to pass the gate, and each step of an autonomous plan is a separately governed decision.
Prompt-injected instructions are governed by the resulting action, regardless of how the instruction arrived.
Every allow and block is an Ed25519-signed, hash-chained record for incident review and replay.
EVE governs what any model or agent is permitted to do; it is a deterministic control plane in front of your AI, not another probabilistic model added to the stack. Charter HARD_BLOCKs are enforced regardless of autonomy level. See EVE Agent Infrastructure and Security.
We run one of your real decisions through the deterministic gate, show the ALLOW / MODIFY / BLOCK verdict, and let you replay it and verify the signature offline. Founding design-partner pilot from $27,500 (standard $37,500).
