Built for environments that cannot leak.
Steinn Labs is engineered for organizations whose regulators, boards, and customers expect their data to stay where it lives. Our security posture is part of the product, not a downstream policy document.
Six pillars.
Sovereign deployment
All training and inference happens inside your environment — your cloud account, your VPC, or your on-premise infrastructure. Steinn never operates as a hosted inference endpoint over your data.
Identity & access
Integration with your existing SSO, RBAC, and privileged-access tooling. Service accounts are scoped, rotated, and logged through your standard controls.
Auditability by default
Every inference is signed, versioned, and reproducible. Models, prompts, weights, and evaluation runs are tracked through a tamper-evident registry your auditors can query.
Encryption & key management
Data is encrypted in transit and at rest using your KMS. Steinn never holds your encryption keys.
Change control
Models follow the same change-management discipline as the rest of your production stack — challenger validation, sign-off, rollback, and post-deployment monitoring.
Vendor assurance
We participate in your standard third-party risk process, including questionnaires, evidence requests, and remediation tracking.
Aligned to the standards your auditors use.
