PlainID: The Enterprise Standard
for Interoperability & Compliance
Leading analysts converge: authorization is the critical layer for governing access across human and non-human identities. Built on a flexible architecture, PlainID’s enterprise-grade platform works natively with your existing stack to deliver out-of-the-box auditability and continuous governance.
Protocols & Standards
Universal interoperability
across your stack
PlainID natively supports the industry’s leading standards to deliver interoperability across your entire technology stack.
- AuthN & AuthZ
OpenID Connect (OIDC)
Identity layer built on OAuth 2.0. Enables secure verification of end-user identity via standardized JWTs passed between applications and authorization servers.
- AuthZ
OpenID AuthZEN
Standardizes the API format for PEP-to-PDP communication. Universal JSON-based access requests evaluate subject, resource, action, and context to return boolean decisions.
- Community proposal
- Emerging
OIDC for Agents & Delegated Authority
Proposes explicit delegated authority for AI agents using on-behalf-of flows. Embeds distinct identities for human delegator and acting agent within access tokens.
- Policy Language
OPA Rego
Open-source declarative policy language used by Open Policy Agent to define policy-as-code across cloud-native stacks.
- AuthZ
OAuth 2.0 Rich Authorization Requests
RFC 9396 extension enables clients to specify granular permissions during authorization requests, producing highly detailed “smart” access tokens.
- Agentic AI
- Emerging
Model Context Protocol (MCP)
Open protocol standardizing how AI agents discover and call external tools and data sources. Its authorization spec builds on OAuth 2.1 to scope what an agent may invoke.
- Identity Mgmt
SCIM
Open standard for automating user identity synchronization across identity domains and IT systems — keeping identity data consistent enterprise-wide.
- Identity Mgmt
LDAP
Open protocol (RFC 4511) for querying enterprise directory services. Supplies user, group, and attribute data as a live identity source for runtime policy decisions.
- Data Access
SQL
Standard query language for relational data, with vendor dialects extending the ANSI core. Provides row-level filtering and column masking expressions evaluated at query time.
- AUTHN & AUTHZ
SAML 2.0
OASIS standard for exchanging signed authentication and authorization assertions between an identity provider and a service provider, widely used for enterprise single sign-on.
- Workload Identity
SPIFFE
CNCF standard for issuing cryptographic workload identities (SVIDs) to services, enabling mutual authentication between workloads without shared secrets.
Gartner® recommends IAM leaders adopt
interoperable authorization standards
Reduce vendor lock-in and facilitate interoperability between authorization components by monitoring and adopting emerging standards like AuthZEN. Only favor vendors who support interoperable authorization standards.

Industry Frameworks
PlainID is aligned to leading security
& governance frameworks
A runtime enforcement layer that maps directly to foundational enterprise security standards, from Zero Trust architecture to AI governance.
- AI Governance
Gartner® AI TRiSM
A Runtime Inspection & Enforcement layer, applying continuous, context-aware authorization so AI agents reach only the data and APIs their active policies permit.
- AI & Agentic Security
OWASP Top 10 for LLMs
Excessive Agency, enforcing least-privilege authorization at runtime to constrain the functionality, permissions, and autonomy an AI agent can exercise without explicit, continuous authorization (LLM06).
- Zero Trust & Governance
NIST SP 800-207
PlainID acts as the core policy decision and enforcement engine for Zero Trust architectures, enabling continuous, context-aware authorization in line with NIST’s core principle: no implicit trust.
- AI Governance
CSA Agentic AI IAM
PlainID maps to the Dynamic Access Control function in the CSA’s Agentic AI IAM architecture, governing autonomous agents within explicitly defined, secure boundaries.
- AI Governance
MAESTRO (CSA)
Within the MAESTRO framework, PlainID provides runtime authorization guardrails governing Data Operations (L2), Agent Frameworks (L3), and Security & Compliance (L6).
