Authentik: Managed Hosting, Installation and Operations
WZ-IT plans, installs and operates Authentik as managed hosting, in your cloud or on premises. Depending on the target design, we also provide migration, secure network and identity integration, monitoring, backups, updates, integrations and further development.
Companies worldwide trust WZ-IT
The following are trademarks of their respective owners: authentik (Authentik Security Inc.). WZ-IT is an independent service provider and has no business, partnership, or contractual relationship with these companies. We offer independent migration, installation, hosting, and operations services.
About the Technology
What is Authentik?
Authentik is a self-hostable identity provider for single sign-on and access control. Operating it yourself enables controllable data flows and integration with existing identity sources.
As a Zero Trust Gateway, Authentik implements granular access control based on user identity, device, location, and behavior. The solution supports modern standards like OAuth2, OpenID Connect, SAML2 and provides seamless integration into existing infrastructures.

Ready for Authentik?
We install, host and operate Authentik for your company - either on our secure, privacy-focused infrastructure in Germany or other locations, as well as on-premise in your own environment.
We provide 24/7 monitoring, backups and maintenance for your Authentik instance. Human response times and support coverage follow the selected service level. Note: specific Enterprise connectors (Google Workspace IdP, Microsoft Entra, RADIUS EAP-TLS, mTLS, advanced audit logs) require an Authentik Enterprise license key - we support selection and coordination of the appropriate licence; the licence agreement is concluded with the respective vendor.
Self-host Anywhere
Run Authentik on your Docker or Kubernetes infrastructure with a controllable data location, network access and update process.
Single Sign-On (SSO)
Unified login processes across all applications with support for industry-standard protocols.
Multi-factor Authentication
Comprehensive MFA support with TOTP, WebAuthn/Passkeys in hardware or software for maximum security.
Conditional Access Control
Granular policies based on user attributes, time, location, and more for precise access control.
FIDO2 & Passkey Support
Passwordless authentication using FIDO2 standards for a secure, phishing-resistant login experience.
Zero Trust Architecture
Implementation of Zero Trust principles with fine-grained access controls and continuous verification.
GeoIP & Impossible Travel Detection
Detection of suspicious login attempts based on GeoIP location and travel patterns to prevent unauthorized access.
Advanced audit logging with Enterprise
Field-level audit details require an appropriate Authentik Enterprise licence. Scope, retention and analysis are defined in advance.
Comprehensive Protocol Support
OAuth2/OpenID Connect, SAML2, LDAP, RADIUS, and SCIM for seamless integration into existing systems.

Architecture & Interfaces
Authentik Development & Integration
Authentik is extremely flexible because every authentication step is a 'stage' in a 'flow'. We use Python to inject logic directly into these flows.
Expression Policies (Python)
Instead of rigid rules, we write Python code for policies. Access only if user is in office (IP range) AND shift plan API reports 'active'? No problem. We integrate external APIs directly into the auth decision.
Custom Flow Stages
When standard stages (MFA, password) aren't enough, we develop custom stages. For example, querying a proprietary hardware token database or legal disclaimer confirmation with versioning.
Blueprints & IaC
We don't configure Authentik manually. We define your complete IAM logic as code (Blueprints). This allows reproducible setups for Dev/Staging/Prod and disaster recovery.
Concrete Use Cases
How we implement Authentik development in practice.
Legacy System Migration
Problem
User passwords are in an old Oracle DB with proprietary hash algorithm. Resetting all passwords is not an option.
Solution
A custom password stage checks login attempts against the old database. Upon success, Authentik transparently migrates the user and re-hashes the password to modern standards.
Dynamic Permissions
Problem
Group membership alone is insufficient. Permissions depend on project status or certifications stored in third-party systems.
Solution
A policy queries your HR API or project software upon login and dynamically injects permissions as claims into the OIDC/SAML token.
Specialized MFA Methods
Problem
TOTP or WebAuthn aren't possible (e.g., in high-security areas without smartphones), smartcards or matrix cards are used instead.
Solution
Implementation of a custom MFA stage mapping the challenge-response logic of your physical tokens.
Infrastructure, integration and operations
Authentik as part of your infrastructure
We do more than provide an application. WZ-IT designs the technical architecture, integrates network and identity, operates the agreed scope and develops integrations when the standard product is not enough.
Network and identity
SSO, secure access, internal systems and existing security components are integrated appropriately.
Monitoring and service level
Updates, backups, technical monitoring and response paths follow a transparent operational scope.
Integration and development
APIs, automation and custom extensions can be delivered beyond basic deployment.
The exact scope depends on the application, edition, infrastructure and criticality. Vendor licences and non-standard components are quoted separately.
Target architecture
Integrate Authentik into your infrastructure with clear controls
Identity platforms sit in the critical access path. Directory, policies, keys, target applications and emergency access must be designed together.
Users, devices and applications
Internal and external identities sign in to connected services through defined flows.
Secure access
TLS, firewall rules, reverse proxies or private network paths are designed around the platform's exposure.
Identity and permissions
Local accounts, SSO, directories, service accounts and emergency access are connected through clear roles.
Authentik platform
Authentication, authorisation, policies, tokens and administrative access are controlled centrally.
Directory and identity data
Local accounts, LDAP/AD, groups, attributes and governed provisioning.
Keys and recovery
Secrets, signing keys, database, backups and documented emergency access.
Connected applications
OIDC, OAuth 2.0, SAML, LDAP or application-specific integrations.
The diagram is a resilient target model. Its implementation depends on edition, data flows, load, availability objectives and existing infrastructure.

Mr. Wevelsiep and Mr. Zins responded to every one of our questions patiently, promptly and respectfully, and contributed their own suggestions and good ideas on how to modernize our server infrastructure and adapt it even better to our needs. Throughout, WZ-IT consistently kept our need for data sovereignty and GDPR compliance in mind. Even short-notice adjustments and change requests from our side were implemented quickly and patiently and integrated consistently into the overall concept. From planning to the final handover, every step was documented transparently and comprehensively - so if a provider change should ever become necessary, the documentation would let us onboard a successor into our infrastructure very quickly. We are extremely satisfied with WZ-IT and hope to continue working together for a long time.”
