PlainID

PlainID Runtime Authorization Platform

Centralize Authorization. Enforce It Everywhere.
One platform to discover, manage, and enforce authorization for every identity – human, non-human, and AI agent – across applications, APIs, microservices, data, and agentic AI.

Centralized policy management gives organizations consistency, visibility, and governance. Distributed decisioning and pre-built Authorizers enforce fine-grained access close to the resource, with the performance, resilience, and flexibility required for enterprise environments.

Discover

The Discover stage builds the context needed to write policy. It identifies and enriches identities, AI agents, resources, MCP servers, tools, APIs and data sources, and maps the access relationships between them. It can also discover authorization policies that already exist inside connected platforms, and adds ownership, purpose, sensitivity and risk context to what it finds. The platform surfaces both direct and indirect access paths.

Manage

The Manage stage is where policy is written and governed. Business and security teams can author policies in a visual interface, while developers can work with policy as code. Governance features include:

• Versioning, approvals and controlled promotion between environments such as staging and production
• A policy simulator for testing and impact analysis before changes go live
• Certification campaigns, audit reporting and business-readable explanations of decisions
• Delegated administration with separation of duties
• Policy360, a connected view of every policy, its dependencies and its change history

Enforce

The Enforce stage evaluates each request against policy using identity, resource, action, business, environmental and risk context. Decisions go beyond a simple permit or deny. Depending on the integration, PlainID can return allowed operations or entitlements, row and document filters, column and response masking, token claims and scopes, permitted tools for an AI agent, constraints on tool parameters, and obligations such as approval or step-up authentication.
