PlainID

PlainID provides an enterprise authorization and identity security platform built on Policy-Based Access Control (PBAC). The platform is organized around three functions — discovering access control policies and authorization gaps across the enterprise, managing and standardizing fine-grained policies centrally, and authorizing individual interactions in real time at runtime. Coverage spans business applications, APIs and microservices, data platforms and data sets, infrastructure, and agentic AI workflows, with access decisions applied to both human and non-human identities.

The product set includes a runtime decision engine, a Policy 360° view that consolidates policy logic, metadata, dependencies and lifecycle steps in one interface (with details, rules, code, native-format, audit and graphical map views), and an Integration Hub of out-of-the-box "Authorizers" and connectors to identity providers, cloud applications, APIs, microservices and data platforms. Policies can be authored and edited directly in Rego, and vendor-specific native policy formats can be managed without recoding. Earlier product lines announced by the company included Policy Manager and Partner Manager.

The company positions itself in the identity and access management market as complementary to identity providers and privileged access vendors rather than a direct replacement, and its materials describe use cases in regulated sectors such as financial services and healthcare. Analyst firms Gartner and KuppingerCole have listed PlainID as a representative provider or sample vendor in reports covering authorization management platforms, policy-based access management, data security platforms, API security, identity governance and IAM for AI agents.
