Discover
Automatically surface all human roles, non-human endpoints, and AI agents alongside their associated data, tools, APIs, and access relationships. Build complete visibility of your ecosystem before applying controls.
Secure Every Identity
Across Your Tech Stack
One control plane governs humans, machine workloads, and agents. Policy decisions calculated at runtime, at the point of access.
One Control Plane to Secure Humans, Non-Humans, and AI Agents
Today's distributed architectures, dynamic data lakes, and AI agents require a continuous, real-time security control plane. Take control of what identities can access, do, and expose by enforcing policy-driven decisions dynamically at runtime, close to where access occurs.
End-to-End Governance for Modern Access
PlainID is the only platform that delivers the full authorization lifecycle under a single policy language, spanning all identity types:
Manage
Define and govern authorization policies centrally using a business-friendly visual builder or developer-first code. Test, version, simulate, and audit policies under a single pane of glass.
Enforce
Distribute enforcement close to workloads via pre-built Authorizers across gateways, microservices, and databases. Deploy policy updates globally in under 60 seconds with sub-two-millisecond runtime execution.
Secure Every Identity. Govern the Entire Chain of Access.
We apply a single, continuous, Policy-Based Access Control (PBAC) model across your entire identity fabric
Human: Static roles cause access creep
Eliminate access creep Extend your IdP One policy for workforce and consumers
Non-Human: Machine IDs outnumber humans
Zero standing privileges Keep microservices in check Context at decision time
Agentic: Agents chain decisions
Guard the prompt layer Control MCP + tools Mask the output
Secure the Entire Access Chain, Not Just the Actor
When an AI agent acts, it rarely does so in isolation. A human user delegates a task to an agent, that agent calls a microservice API, and that service retrieves data from a warehouse.
Useron-behalf-of accountability
Agentagent-to-agent governance
Servicepurpose-bound access
Data
Traditional access systems fail here because they collapse the multi-hop transaction, stripping away vital context and inheriting broad, unmonitored machine permissions.
PlainID solves this with Cross-Identity Authorization, binding every player in the transaction into a single, secure chain.
Composite identity evaluation
Human, agent, service, and resource checked as one chain
On-behalf-of accountability
Every hop traces back to the person who started it
Agent-to-agent governance
Control which agents can call or delegate to others
Purpose-bound access
Grant only what this step needs, nothing standing

Common Questions
Yes. PlainID provides a single, standardized policy control plane. You write your authorization policies once in a plain-language visual builder, and the platform automatically translates and enforces those rules across human actions, API routes, service-to-service connections, and agentic LLM prompt-to-output guardrails.
It depends on your current security architecture and immediate operational focus:
- Choose the PlainID Platform (Enterprise Authorization Control Plane) if you need comprehensive access governance across your entire enterprise tech stack. The core platform centralizes policy administration while distributing runtime enforcement across human users, microservices, APIs, applications, and structured/unstructured data platforms. It eliminates static role explosion, access creep, and over-privileged standing access by enforcing dynamic, context-aware Policy-Based Access Control (PBAC) and Zero Standing Privileges (ZSP) through externalized decisions or native policy orchestration.
- Choose the Agentic AI / Agentic IAM Solution if you are deploying autonomous AI agents, LLMs, RAG pipelines, or Model Context Protocol (MCP) servers and need dedicated, identity-first guardrails. Built as an extension of the core PlainID foundation, it governs the full agentic access path across five transactional stages (Prompt, Retrieval, MCP/Tools, Action/API, and Output) and enforces Cross-Identity Authorization (Composed Identity) to prevent rogue actions and privilege escalation during multi-hop agent transactions.
Absolutely. PlainID is built as a single, unified authorization control plane. You can combine and run these solutions simultaneously under one central policy language. In fact, securing modern workflows often requires combining them. For instance, when a human user delegates a task to an AI agent, which then triggers a microservice to query a database, PlainID evaluates the entire transaction using Cross-Identity Authorization. This binds the human, agent, service, and data resource contexts into a single, secure, and fully auditable execution chain.
Yes. PlainID supports dual operating models. You can choose to externalize decisions for modern applications via high-performance Policy Decision Points (PDPs), or use our Policy Orchestration model to discover, compare, and synchronize access rules natively inside legacy databases and SaaS systems without rewriting code.
Absolutely. PlainID is built on principles of open interoperability. While it provides a central, visual no-code console for business teams, policies can be modeled as code, are fully compatible with OPA/Rego, and align natively with the OpenID AuthZEN interoperability standard.
PlainID is designed for hybrid enterprise architectures. The Policy Administration Point (PAP) is SaaS-hosted for simple management, while Policy Authorization Agents (PAAs) and Policy Decision Points (PDPs) are deployed as containerized packages (Kubernetes via Helm) that run locally in your cloud, hybrid-cloud, or on-premises infrastructure.
