How does Liminal protect sensitive data?

Liminal cleanses and protects sensitive data prior to submission to any LLM, then rehydrates protected terms so the experience stays seamless — total data protection without friction.

How do I control which users and models are allowed?

Secure access management lets you govern which users can leverage which models, and can be implemented at the organization, team, and individual level. Granular controls also let you decide what data types can be shared and how they're treated in AI interactions.

Can I see how AI is being used across my organization?

Yes. Liminal provides real-time observability with full visibility into how generative AI is being used across your organization.

What compliance standards does Liminal meet?

Liminal is HIPAA compliant and SOC 2 Type 1 and Type 2 certified, with ISO 27001, HITRUST, and NIST in progress.
