EVE CoreGuard —
Deterministic AI Enforcement Engine
EVE CoreGuard evaluates every proposed AI action against your policy packs and returns ALLOWED, BLOCKED, or MODIFIED — before the action executes. It fails closed, runs a sub-millisecond deterministic gate, and ships wherever your workload runs.
ALLOWED · BLOCKED · MODIFIED — decided before execution, fail-closed

Enforcement, section by section
Each capability has its own page — start anywhere.
Enforcement →
The pre-execution gate: ALLOWED, BLOCKED, or MODIFIED, decided before the action runs.
Fail-Closed →
When in doubt, deny. Ambiguity, outages, and timeouts resolve to BLOCK — and a record.
Gate Latency →
A pure, side-effect-free decision in well under a millisecond — fast enough to stay in the path.
Policy Packs →
Isolated, versioned, add-only policy per organization. Tenants tighten, never loosen.
Streaming & HITL →
Interrupt unsafe output mid-stream; escalate high-stakes actions to a human.
Architecture →
One non-bypassable gate, between governance and signed evidence.
Deployment →
API, sidecar, Kubernetes, or fully air-gapped on-prem — the same engine, four ways.
Product Deep-Dive →
The full EVE CoreGuard product on EVE AI Core.
One gate, in front of everything
Governance decides, CoreGuard enforces, EVE Proof attests — each plane independent and auditable.

# pip install eve-coreguard from eve_coreguard import CoreGuardClient client = CoreGuardClient(api_key="eve_sk_…") result = client.evaluate( tenant_id="org_acme", proposed_action={"type": "loan_approval", "amount": 50000}, policy_set="lending_v1", ) print(result.verdict) # ALLOWED | BLOCKED | MODIFIED
// npm install eve-ai-governance import { GovernanceClient } from "eve-ai-governance"; const client = new GovernanceClient({ apiKey: "eve_sk_…" }); const result = await client.evaluate({ tenant_id: "org_acme", proposed_action: { type: "loan_approval", amount: 50000 }, policy_set: "lending_v1", }); console.log(result.decision.status); // ALLOWED | BLOCKED | MODIFIED
