Secure AI Enablement with Data Protection and Governance

Liminal.ai positions itself as a horizontal, model-agnostic guardrail platform for enterprise generative AI and secure workflows. The company targets regulated industries such as banking, healthcare, biotech, insurance and the public sector. Its platform supports “unlimited access” to leading models (e.g., OpenAI, Anthropic, Google) alongside private or custom models, while implementing data protection, observability and governance controls across any application or workflow.

Key capabilities include prompt-level sensitive data detection (PII/PHI/IP/Trade Secrets), policy enforcement (masking, rehydration), single-tenant architecture, desktop/ browser extensions to secure AI interactions in everyday productivity tools, and auditable logs/alerts for security teams.

Founded in 2023, Liminal.ai took in $5 million in June 2024 in a seed round led by Fin Capital.
