Runtime assurance for AI systems
AI inference is the new endpoint.
We defend it.
GLACIS sits inline at the inference boundary. We enforce what runs, block what shouldn’t, and emit signed proof your auditors, customers, and insurers can verify themselves.
The defense layer
One control plane. Three guarantees.
A runtime arbiter that sits inline in your AI request path. Observes every action. Enforces every boundary. Signs proof of both.
See
Every inference. Every tool call. Every decision.
Causal chains across models, agents, and tools — not log dumps. Tamper-evident at the event level.
Control
Block what shouldn’t run. Allow what should.
Inline at the inference boundary. Deterministic, policy-driven, model-agnostic. No retraining, no swap.
Prove
Signed. Witnessed. Portable.
Every decision becomes an OVERT receipt, countersigned by an independent witness. Verifiable without a GLACIS account.
Receipt chain
What an auditable AI decision looks like.
Every action becomes a receipt. Hash-chained to the previous. Countersigned by an independent witness. Tamper one, the chain breaks — and the verifier shows where.

What the buyer asks for
The audit perimeter is moving.
Insurers are starting to ask. Regulators are starting to require. Customers are starting to demand. The artifact they all want is the same one — and until OVERT, it didn’t exist as something portable enough to send.
- InsuranceE&O carriers are carving out autonomous-agent action. The carve-out closes when you can hand them runtime evidence.
- RegulationEU AI Act post-deployment monitoring and Colorado AI Act consequential-decision logging both require what a receipt is.
- ProcurementEnterprise AI vendor reviews now ask for runtime audit artifacts a third party can verify — not a SOC 2 report.
Where GLACIS fits
Not a governance tool. Not an eval suite. Not another log.
Adjacent categories solve adjacent problems. GLACIS is the only layer that stops an AI action in flight and produces proof a regulator, customer, or insurer can verify themselves.
| Runtime enforcement | Signed evidence | Portable proof | |
|---|---|---|---|
| Governance platforms OneTrust · Credo · etc. |
— policy only | — PDF reports | — vendor-locked |
| Model evals Patronus · Galileo · etc. |
— pre-prod only | — eval scores | — vendor-locked |
| LLM observability LangSmith · Helicone · etc. |
— log only | — unsigned | — vendor-locked |
| GLACIS | ✓ inline arbiter | ✓ OVERT receipts | ✓ independent witness |
