AuthZEN in cidaas:
One decision layer everywhere
Make authorization decisions once and enforce them everywhere. AuthZEN in cidaas standardizes authorization across applications, APIs, and services using OpenID.
Policy-as-code using the policy language Rego and Open Policy Agent. No proprietary lock-in.
Real-time
Context-aware
Scalable
Authorization in complex environments
In modern IT landscapes, authorization grows faster than the app portfolio: Microservices, APIs, cloud deployments, multiple teams, Non human identities and constantly evolving requirements.
When permission logic is embedded in code, the following challenges can arise:
Key challenges
-
Inconsistent access rights across applications and services
-
High audit and compliance effort because rules are difficult to trace
-
Increased time-to-change since adjustments require deployments
-
Security risks when roles, exceptions, and contextual rules diverge uncontrollably
AuthZEN addresses exactly this issue: authorization becomes a standardized process instead of a side feature of individual applications.
Policy-based authorization:
Define once, enforce everywhere
In cidaas, AuthZEN is used as a central decision layer for your access control:
Unified permission checks for resources, actions, and context
Decoupled architecture: Modify policies without redeploying services
Standardized authorization requests instead of proprietary interfaces
With policy-based authorization based on AuthZEN, companies create repeatable authorization logic that relieves development teams and cleanly reflects security requirements.
How AuthZEN fits into your architecture
AuthZEN does not replace IAM, CIAM, or an identity provider. Instead, it complements your identity foundation with standardized decisions. How the architecture works together:
01. Identity Provider IDP
Provides identity and claims via OAuth 2.0 or OpenID Connect protocols.
02. Policy Enforcement Point PEP
Enforces decisions at API gateway level.
03. Policy Decision Point PDP
Evaluates policies and returns decisions.
04. Policy Information Point PIP
Supplies attributes like role and risk.
05. Real-time Result RT
Verification is processed instantly.
Key capabilities with cidaas AuthZEN
Policy as Code with Rego (OPA-based)
Define policies declaratively in Rego and version them as code. This simplifies reviews, testing, and traceability, especially for complex rules that require rigorous compliance.
Context & attribute PIP-ready
Decisions are not limited to roles: policies can consider attributes and context such as department, cost center, location, risk levels, and resource properties.
- Geographic Location
- Risk Window Analysis
- Resource Sensitivity
Standards-based integration
Use AuthZEN in cidaas as a unified interface for authorization requests — regardless of whether the application runs internally, with partners, or as a microservice.
Identity & Auth Separation
cidaas remains your identity foundation (IAM or CIAM). The AuthZEN function complements the enforcement model, reducing policy chaos in application code.
Roll-out ready for teams
Designed for developer experience: Clear requests, reusable patterns, and a consistent way to establish authorization across multiple teams effortlessly.
RBAC & PBAC with AuthZEN –
what companies gain
Role-based access control
Many organizations start with role-based access control (RBAC) : Fast, understandable, stable for classic role profiles.
Policy-based access control
As soon as context matters or rules change frequently, policy-based access control becomes relevant: Centralized policies instead of distributed logic.
AuthZEN connects both: Applications can submit standardized authorization requests, and the decision comes from policies. This allows RBAC models to be extended cleanly without redefining the permission model each time.
Practical use cases
AuthZEN brings policy-as-code to every layer of your stack – standardizing access decisions across APIs, microservices, portals, and SaaS tenants.
API authorization for internal and external APIs like partners, integrations and apps
Microservices with consistent allow or deny decisions per service
Admin backends & back-office portals with fine-grained permissions
Employee portals (e.g., procurement or finance): Approvals, reviews, role profiles and orders for instance
Multi-tenant SaaS: Isolate policies per tenant while reusing shared rules
Security, governance & compliance readiness
AuthZEN improves access control where security decisions actually happen: with every request. Standardized requests and responses, clear responsibilities (PEP, PDP, PIP), and policy-as-code create the foundation for:
Traceable decisions instead of implicit code logic
Consistent rules across teams and applications
Improved auditability because decisions are reproducible
Digital sovereignty with cidaas
With the AuthZEN function in cidaas, organizations retain full control over their authorization decisions. Access rules are not hidden in application code but implemented centrally, transparently, and based on open standards.
cidaas relies on open standards such as AuthZEN, OAuth 2.0, OpenID Connect, and OpenID. Our platform is hosted exclusively in Germany and the EU. Policies, decision logic, and identity data therefore remain under European jurisdiction at all times – transparent, auditable, and free from non-European dependencies.
AuthZEN thus becomes a sovereign decision layer for modern, secure access control.
