Runtime trust for AI agents

The agent economy
runs on proof.

AI is starting to act on its own — approving claims, writing notes, calling tools. Glacis sits in the path, enforces the controls that matter, and turns each action into proof an auditor, insurer, or the next agent can verify.

§ The Gap In The Wall

Asserted compliance was a promise. Autonomy calls the bluff.

Even today, your SOC 2 proves a policy existed — not that the control ran on the inference that mattered. Autonomy makes that gap unbounded, and increasingly the next reviewer is another agent moving at machine speed. We close it: every inference produces proof the control ran.

Glacis · Proven
The control cryptographically ran.
  • Every inference produces a signed, witnessed receipt.
  • The Arbiter sits in the call path — nothing routes around it.
  • Auditors and insurers verify offline against a signed tree head.
  • The next agent reads the receipt and decides whether to proceed.

§ Why We Win

Everyone else observes, asserts, or finds.
We prove.

The market splits in two — design-time posture that asserts, and runtime tools that observe. No feedback between them; the customer is the glue. We close the loop.

XBOW finds a hole in March; we prove the control holds on every inference. We don’t replace GRC — we make it honest.

§The Endpoint Moves

Antivirus died. Guardrails are dying. We live in the wire.

Every era of defense follows the same arc: the attacker moves down a layer, and the gate has to move with it. AI inference is the new endpoint — and tool-use is the new output. The blast radius moved from a wrong sentence to a wrong action.

§ Asserted, Or Proven

Don’t trust us. Verify.

Your GRC stores a control someone asserted was met. This is the control cryptographically proving it ran — on this inference, just now.

An auditor verifies it offline against the signed tree head. So do your insurer, your customer, and the next agent in the chain. You don’t have to trust us, or even your own team.

§Moat · Proof As A Financial Asset

Your proof has a market price.

Insurers can’t price what they can’t measure. Testudo — a Lloyd’s cover holder — has a distribution MoU out for redlines, underwriting against five truth-gated, privacy-preserving telemetry markers — values that report only when signed evidence backs them. When the market prices your proof, governance stops being a cost and becomes an asset.

§ Why Now

Proof just became a buying criterion.

Regulation is phasing in, insurers are excluding black-box AI liability, and enterprise buyers now ask for evidence in the security review. The first vendor to hand over cryptographic proof wins the contract — the rest hand over a PDF and a promise.

§ Go To Market

Land a sprint. Become the standard.

A paid 30-day proof sprint lands beside the incumbent — no rip-and-replace. Receipts compound into a ledger that’s costly to leave.

Day 1 — 30 · LAND
Paid proof sprint

Switch from observe to enforce — now in-line, blocking in real time. Wire the second and third system. Receipts feed GRC; the ledger becomes the system of record.

§ Momentum

Customers, standards, insurers, regulators
— converging on one thesis.

Commercial deals in contracting, diligence-grade names in late-stage pipeline, a Lloyd’s cover holder and a standards body at the table — the same pitch, pulling the same way: proof is becoming the buying criterion.

§ Appendix A1 · Independence

Why you don’t have to trust us.

Most vendors collapse the thing being governed and the thing doing the governing into one box. OVERT holds them apart by construction — self-attestation is non-conformant.

Four roles, held apart
  • The standardDefines what implementations shall prove. Open, royalty-free, patron-governed — overt.is.
  • Arbiter · the AttesterOperator-side, in the call path, sees plaintext. Generates receipts — but cannot vouch for itself.
  • Notary · the Verifier (IAP)Structurally independent of the operator. Derives the Arbiter’s binary identity itself; counter-signs t‑of‑n.
  • Transparency logPublic, append-only. Anyone audits consistency — no operator trust required.

AAL‑4 requires a notary run by an entity independent of the operator. Run your own and you cap at AAL‑3.

Even if the operator cheats
  • … swaps the Arbiter binaryIdentity is notary-derived from a hardware-rooted measurement — not a client-supplied claim.
  • … games which calls get sampledThe epoch nonce is CSPRNG-generated, committed before the epoch and revealed after.
  • … colludes with notariest‑of‑n agreement; no entity controls t nodes, shares a parent, or a jurisdiction.
  • … equivocates on the log≥ 2 independent monitors gossip Signed Tree Heads; split views are detected.
  • … narrows mediation scopeScope is published to the log; coverage is computed against independent ingress counts.

§ Appendix A2 · Construction

A receipt you can verify offline.

Three constructions do the work. None of them require the verifier to see your data — or to trust your logs.

Co-epoch binding

Every receipt is bound to the Arbiter’s binary identity and network-isolation state inside a bounded epoch (~300 s). A strict current-epoch rule (≤ 2 s skew) makes stale or replayed receipts fail.

binary id · net state · epoch → bound

Transparency log

An append-only Merkle tree (RFC 6962). Inclusion proofs show a receipt exists; consistency proofs show the log was never rewritten; split-view detection catches equivocation.

STH · inclusion · consistency

Non-egress commitments

Only keyed commitments cross the boundary — HMAC‑SHA256 over a canonical encoding, keys derived via HKDF and held in the operator’s KMS. Raw content, and even raw digests, never leave the VPC.

HMAC‑SHA256 · HKDF · tenant-scoped

Crypto-agile by mandate: after 2031, pure-classical signatures are non-conformant — hybrid post-quantum constructions are required.

§ Appendix A3 · Statistical rigor

Safety claims carry confidence intervals.

S3P — the operator can’t choose which interactions get measured.

  • Deterministic samplingA PRF over the request commitment and a secret epoch nonce decides membership. No cherry-picking favourable traffic.
  • Commit, then revealThe nonce is hashed and published at epoch start, revealed at close — so an auditor replays every sampling decision from public data.
  • Exact intervalsClopper–Pearson binomial bounds — no distributional assumptions. n_total, n_sampled, n_violations recorded per policy, per epoch.
  • Behavioural driftSequential analysis (CUSUM / EWMA) per dimension against a pinned baseline; response escalates log → alert → block.

§ Appendix A4 · Scope & crosswalk

What we don’t claim.

Precision about limits is how an attestation layer earns its credibility. OVERT proves that controls executed — not that a model told the truth.

Out of scope
OVERT does not
  • ×attest the truthfulness of outputs, or the absence of hallucination.
  • ×prove the absence of compromise, or a successful prompt injection.
  • ×replace endpoint, cloud, network, or model security.
  • ×guarantee legal compliance, regulatory approval, or insurability.
In scope
OVERT does
  • prove declared controls ran, under a known config, in a bounded epoch.
  • produce content-free evidence any third party can verify.
  • carry statistical safety signals with exact confidence intervals.
  • preserve a tamper-evident, offline-verifiable record.

§ Appendix A5 · Insurance signal

Five vital signs an underwriter can recompute.

The actuarial telemetry report, built with a Lloyd’s cover holder. Every marker is truth-gated and carries receipt IDs — so an underwriter verifies it in their own tooling, with zero trust in Glacis.
