The record

What it does: Glacis places runtime controls in the path of AI actions and creates signed records of covered decisions for external verification.
Control decisions: For actions that cross configured bounds, Glacis can constrain, hold for a person, or deny the action; it can also allow actions through unchanged.
Managed service: Glacis says it runs nine production components as a managed service, while working with the identity provider, cloud, and security systems the customer already uses.
Records: Records are signed and use OVERT, an open record format; a verifier can check a record in a browser without a Glacis account.
Data handling: The site says payloads stay in the customer’s environment and records carry hashes; protected fields can be left out, depending on deployment setup.
Evidence pack limitation: Glacis does not offer automated evidence-pack export today; packs are assembled by hand for a particular review.
Verification limits: A record check does not establish whether an action was correct, every event was captured, or a system is safe or compliant.
Open standard: OVERT is a published open record format that implementers and reviewers can inspect and use without a proprietary schema.
Who it serves: The signup form lists AI sellers serving healthcare or other regulated buyers, healthcare AI overseers, AI-agent builders or operators, and people evaluating the product.
Deployment evaluation: The contact page describes a six-week evaluation on the workflow a customer is reviewing.
Support: Glacis says it typically replies to contact requests within one business day and takes on a small number of managed deployments each quarter.
Security reporting: The vulnerability disclosure policy says Glacis aims to acknowledge reports within three business days and provide an initial assessment within ten business days; it offers no bug bounty.
