About

Liminal is a secure AI enablement platform that acts as a central hub for organizations to safely access and administer AI. Employees get unlimited access to the latest models from every leading provider. Security and compliance teams get the governance layer: policy enforcement, data protection, and complete visibility into every interaction. Sensitive information is detected and protected inside the prompt before it reaches any model, then restored in the response, so output stays useful while protected data remains within the organization's control. Policies are defined by data category and applied automatically: mask, redact, warn, or block. Every interaction is logged with the user, model, policies applied, and violations detected, so compliance is evidenced rather than reconstructed. Single-tenant architecture, role-based access control, and SSO. Built for financial services, banking, healthcare, insurance, education, government, and life sciences.

About

Proofpoint AI Security is a unified platform designed to help enterprises govern, monitor, and protect the use of AI systems, large language models, and autonomous agents across the organization. It provides visibility into both sanctioned and unsanctioned AI usage, enabling security teams to discover shadow AI tools, observe prompts and responses, and understand how AI interacts with sensitive data in real time. It applies intent-based detection and behavioral analysis to identify anomalies, prompt injection attempts, and risky interactions, while enforcing policies directly during runtime to prevent data leakage and misuse. It reconstructs full AI transactions, from user input to agent actions and outcomes, giving organizations complete traceability and audit readiness. With controls that extend across endpoints, browsers, and AI agent connections, it enables granular access governance and ensures that AI systems only access and share appropriate information.
