Extend authorization to AI agents without changing your architecture
Traditional access control was built for static systems, where permissions were defined in code, decisions made at login and the visibility into what happened after access was granted was limited. But today, APIs, microservices, and data are highly dynamic, machine identities outnumber humans, and AI agents act autonomously across systems.
PlainID is the market-leading runtime authorization platform, enabling organizations to centralize policies and enforce decisions across their entire technology stack.
Zero Standing Privileges removes default access entirely, ensuring no identity, human or non-human, has ongoing permissions by default. Access is granted just-in-time, scoped to a specific action, and revoked immediately after use. This approach minimizes blast radius, reduces the risk of privilege abuse, and ensures every action is continuously evaluated based on real-time context, identity, and intent.
Policy-Based Access Control (PBAC) shifts authorization from hardcoded logic to centralized, dynamic policies. Instead of embedding permissions in applications, organizations define access rules once and enforce them consistently across systems. Every request is evaluated in real time based on identity, context, and business logic, enabling fine-grained control, full auditability, and the flexibility required to secure modern architectures, including APIs, data platforms, and AI systems.
Agentic AI introduces a new challenge: Autonomous systems that decide what to access, when, and how. PlainID extends your existing authorization model to AI by applying the same policies to humans and agents, enforcing decisions continuously across the AI flow, and controlling what AI can access, do, and expose.
