Every consequential AI decision gets an attestation receipt. OVERT-format, tamper-evident, independently verifiable. Proof builds itself.
Zero-egress architecture
Notarize runs inside your environment alongside the Enforce sidecar. It witnesses every control execution, generates a cryptographic commitment, and emits an OVERT-format receipt. Your data never leaves. Only hashes cross the trust boundary to the GLACIS Witness for independent recording.
GLACIS is architecturally incapable of receiving your data

Crosses the trust boundary. Only hashes.
Independent verification. No vendor lock-in.
What Notarize provides
Notarize generates cryptographic attestation receipts in the open OVERT format. Each receipt proves which controls ran, what the verdict was, and when it happened—without exposing your data.
Open standard for AI attestation. Machine-readable, human-auditable, interoperable across tools. overt.is
Cryptographic commitments make any modification detectable. Receipts can’t be altered after the fact.
Any third party can verify a receipt without access to GLACIS. No vendor lock-in for your evidence trail.
Aggregate governance posture score across your AI fleet. Track improvement over time, share with auditors and buyers.
Your data never leaves your environment. Notarize processes locally and emits only cryptographic hashes across the trust boundary.
OSCAL-compatible evidence packs for auditors. Machine-readable, standards-based, ready for regulatory review.
Who this is for
AI vendors stuck in security review. Your product works. Their security team wants proof. Notarize gives them independently verifiable evidence that controls ran—not just a promise that they will.
Regulated organizations deploying AI. Colorado AI Act, EU AI Act, HIPAA—all require evidence of control execution. Notarize generates that evidence automatically as a byproduct of operation.
Agent developers embedding governance. Your customers need proof. Embed Notarize and hand them a verifiable evidence trail without building attestation infrastructure yourself.
Anyone whose AI decisions have consequences. If an AI output affects a person, a patient, or a financial outcome, you need a receipt. Notarize makes the proof automatic.
How you get it
Every decision on GLACIS is witnessed and receipted — by default, not by upgrade. Turn those receipts into regulator-, auditor-, and carrier-ready Evidence Packs when you need them.
Notarize receipts are part of every Enforce plan. See plans →

Frequently asked questions
An OVERT receipt is a structured attestation record in the open OVERT standard. It contains cryptographic commitments proving which controls ran, what the verdict was, and when—without exposing the underlying data.
Your data—prompts, responses, patient information—never leaves your environment. Notarize processes everything locally. Only cryptographic hashes cross the trust boundary to the GLACIS Witness for independent recording.
Anyone. OVERT receipts are independently verifiable. Your auditor, your customer, a regulator—they can verify without contacting GLACIS or using our tools.
An aggregate governance posture score derived from your attestation receipts. It reflects how consistently your AI fleet is running controls. Share it with auditors, buyers, or your board.
Yes — they work together. Enforce makes the decisions; Notarize proves they happened. Every decision on GLACIS infrastructure is receipted by default, not by upgrade. See plans for details.
