About GLACIS

Governance isn’t a document.
It’s a runtime.

See what your AI systems are actually doing. Enforce your policies when they drift. Generate cryptographic records that prove your controls ran — without data ever leaving your environment.

What We Build

Visibility. Enforcement. Proof.

AI systems are being deployed faster than anyone can verify them. Most teams can’t answer a basic question: is this model doing what we said it would? We build the tooling that makes that question answerable — and provable.

Visibility — Scan

Continuous automated probing that surfaces how your AI system actually behaves in production. Not a one-time eval — a living map of what your model does under real conditions.

Enforcement — Enforce

Policy guardrails that act on drift before it reaches users. When behavior leaves the bounds you defined, Enforce intervenes — automatically, at inference time.

Proof — OVERT & Notarize

Cryptographic attestation that creates a verifiable record of what your AI did, what data it saw, and what controls were active. Built on OVERT (Observable Verification Evidence for Runtime Trust), our open standard for AI accountability evidence. No sensitive data leaves your environment.

We Lived the Problem

We built the “ship fast vs. prove it works” paradox at SwiftKey, Vektor Medical, and Cognoa. We’re not outsiders guessing — we built the systems that needed this infrastructure.

What We Believe

Private by Design

We architect systems so we never see your data. Trust through verification, not promises.

Built for Builders

Accountability that slows you down isn’t accountability — it’s a tax. We optimize for both speed and rigor.

Prove, Don’t Promise

Attestations over assertions. Cryptographic evidence over policy documents.

If you’re building AI systems that need to be accountable — or looking for infrastructure that turns good intentions into verifiable proof — we’d welcome the conversation.
