ZITADEL
ZITADEL is an identity and access management (IAM) platform that provides authentication, authorization, and user management for modern applications and services.
- Cloud-native identity and access management (IAM) platform for enterprises and software providers
- Authentication and Single Sign-On (SSO) services using OpenID Connect (OIDC) (identity federation) and Open Authorization 2.0 (OAuth 2.0) (access delegation)
- Role-Based Access Control (RBAC) and policy management for multi-tenant and B2B/B2C applications (access management)
- Developer-focused APIs, SDKs, and automation features for integrating identity into custom applications and Continuous Integration and Continuous Deployment (CI/CD) workflows (developer tooling)
- Deployment options including managed cloud service and self-hosted installation on Kubernetes and container platforms (hybrid deployment)
More About ZITADEL
ZITADEL operates in the identity and access management (IAM) category, with a focus on authentication, authorization, and user lifecycle management for cloud-native applications and services.
The platform provides standards-based authentication using OIDC (identity federation) and OAuth 2.0 (access delegation), enabling SSO across web, mobile, and API-based applications.
ZITADEL implements concepts such as organizations, projects, and roles to model complex enterprise access structures, including multi-tenant Software-as-a-Service (SaaS) scenarios, partner ecosystems, and internal business units.
RBAC and policy management allow granular authorization logic, including permissions per project, resource, or tenant, which is relevant for B2B and B2C application patterns where isolation and delegated administration are required.
The platform exposes APIs and SDKs (developer tooling) for integrating login, user self-service, and access control into custom applications, as well as for automating user provisioning, configuration, and operational tasks via Infrastructure-as-Code (IaC) and CI/CD pipelines.
ZITADEL supports modern identity protocols such as Security Assertion Markup Language (SAML) 2.0 (federation) in addition to OIDC and OAuth 2.0, which allows interoperability with enterprise directories, HR systems, and other identity providers.
Externally managed identity sources such as enterprise directories or social identity providers can be connected, enabling bring-your-own-identity scenarios and centralized authentication while delegating application-level authorization to ZITADEL.
From an architectural perspective, ZITADEL is designed for cloud-native deployments and supports running as a managed SaaS offering or as a self-hosted instance on Kubernetes and container platforms (cloud infrastructure), which is relevant for organizations with specific compliance, data residency, or integration requirements.
The platform includes features for auditing, logging, and event streams (security and observability) that allow enterprises to integrate identity events into Security Operations (SecOps), monitoring, and compliance reporting workflows.
In marketplace and directory taxonomies, ZITADEL maps to categories such as identity and access management (IAM), customer identity and access management (CIAM), SSO, multi-tenant access control for SaaS providers, and developer platforms for identity integration.
