Permit.io

Permit.io provides fine-grained authorization and access control infrastructure for software applications. The company offers a platform that enables developers to implement and manage authorization policies using multiple models including Role-Based Access Control (RBAC), Attribute-Based Access Control (ABAC), and Relationship-Based Access Control (ReBAC). The platform addresses authorization challenges across traditional applications and modern AI systems. For GenAI and AI agent deployments, Permit.io has developed specialized security capabilities including a Four-Perimeter framework and a dedicated platform called agent.security for enterprise-grade AI agent security. These tools help organizations control what prompts, metadata, and tool calls are permitted to flow between systems and third-party services. Permit.io's authorization engine uses policy decision points (PDPs) that run alongside services to enforce access rules in real-time. The platform allows teams to define granular policies that govern not only user interface actions but also background jobs, data exports, webhooks, and AI tool interactions. Organizations can specify which identities can access which data, under what conditions, and with what level of detail. The company targets SaaS companies, enterprises building GenAI applications, and development teams that need to implement complex authorization logic without building custom solutions from scratch. The platform provides a centralized, auditable system for managing access control policies across an organization's entire technology stack.
