Prove every automated decision was accountable — before oversight asks.
EVE CoreGuard enforces your AI governance policy — aligned to NIST AI RMF, OMB M-24-10, and EO 14110 — on each automated government determination before the model’s output affects a member of the public, and signs a replayable evidence record an oversight body can verify offline. Block the determination you can’t defend.
A model card won’t answer “prove this automated determination was accountable.”
AI is moving into benefits eligibility, fraud and improper-payment detection, citizen-service automation, and procurement. The problem isn’t whether the model is accurate — it’s whether you can prove, decision by decision, that it stayed inside the law and policy. A probabilistic model plus application logs cannot show an auditor why a specific eligibility denial was issued, that the required human-review step occurred, or that a rights-impacting determination met OMB M-24-10’s minimum-risk practices.
Rights-impacting decisions without review
M-24-10 requires minimum-risk practices — including human review and documented basis — for rights- and safety-impacting AI. A determination issued without them is a control gap, and these scale fast across a program.
Decisions the public can’t contest
When an automated determination affects a person’s benefits or status, they are owed a defensible, explainable basis. Without a replayable record of why a determination was made, the decision is hard to contest — or to defend.
Accountability & documentation gaps
The AI RMF expects controls that are accountable, transparent, and auditable across Govern and Manage. Probabilistic outputs that drift with model version meet none of those.
Inconsistent determinations
If the same applicant profile can get different outcomes across model versions, you can’t explain — or defend — why a given determination happened, undermining the consistency public-sector AI is expected to demonstrate.
Deterministic enforcement, then signed evidence — on every decision.
CoreGuard sits in front of your decision model as a governance layer. It evaluates each proposed determination against
your government_v1 policy pack and returns ALLOW, BLOCK, or MODIFY before the output is used —
then writes a cryptographically signed record of exactly which rule fired and why.
Enforce policy before the determination is used
The government_v1 pack encodes NIST AI RMF and OMB M-24-10 minimum-risk practices. The same input always produces the same governance decision — deterministic, not probabilistic.
Block rights-impacting decisions that skip required review
If a rights-impacting determination is missing the human-review step or documented basis M-24-10 requires, CoreGuard blocks it and records the gap — so the action you take matches the record you keep.
Gate every model update before it reaches the public
Each model change is simulated against your governance policy and blocked before promotion if it shifts outcomes for a protected group. See the EVE Model Update Firewall →
Hand the auditor a record they can verify themselves
Every decision becomes a signed, hash-chained evidence record (Ed25519 in production). Re-hash and re-verify it offline with the public key — no EVE service required. Verify a record →
One prevented governance failure pays for years of control.
The price tag on a single public-sector governance failure dwarfs the cost of the control that prevents it.

Your data never leaves your tenant.
CoreGuard runs as SaaS, in your VPC, or fully on-prem. The governance decision and the signed record are produced inside your boundary — nothing about a member of the public is sent to EVE to make a decision. FedRAMP authorization is on our roadmap; CoreGuard is not yet FedRAMP authorized. See deployment models →
SaaS
Fastest start. Decisions and signed records produced in an isolated tenant. FedRAMP authorization is on the roadmap, not yet held.
VPC / Private
Runs inside your cloud account, under your network and key controls.
On-prem
Air-gap-friendly for programs that keep automated decisioning fully in-house.
Auditor access
Issue scoped, time-boxed evidence links so an auditor or IG can verify records directly.
Public-sector AI governance, answered plainly.
Bring one automated decision workflow under deterministic governance.
A 60-day design-partner pilot puts CoreGuard in front of a single decision flow, produces signed evidence on real determinations, and credits the pilot fee toward your license.
