Authentik Development & Integration
Custom extensions, API integrations, and seamless embedding into your system landscape.
Standard software often covers 90% – we close the last gap. We develop Policies & Stages, connect Authentik with your tools, and automate workflows.
Our Development Services
From API integration to complete custom solutions – we cover the entire spectrum.
API & Interface Integration
We make your systems talk to each other. Whether REST, GraphQL, or webhooks – we connect software with your CRM, ERP, or identity provider.
- Bidirectional data synchronization
- Third-party system connections
- Custom webhooks & event handlers
- Legacy system integrations
Custom Middleware & Logic
Often data formats from System A don't match System B. We develop middleware that sits in between, transforms data, and controls processes.
- Transformation layer (ETL)
- Data stream validation
- Caching layer for performance
- Microservices architecture
Embeddings & Custom Apps
Want to use software features in your own intranet or customer portal? We embed software headlessly and build custom UIs around it.
- White-label integration
- Custom dashboards (React/Vue)
- UI extension via plugins
- Mobile app customizations
Automation & Bots
Save manual work through intelligent automation. We develop bots and scripts that handle tasks automatically.
- ChatOps & slash commands
- Automated reporting
- Workflow orchestration
- Trigger-based actions
Flow-Based Authentication & Python Policies
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
User passwords are in an old Oracle DB with proprietary hash algorithm. Resetting all passwords is not an option.
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
Group membership alone is insufficient. Permissions depend on project status or certifications stored in third-party systems.
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
TOTP or WebAuthn aren't possible (e.g., in high-security areas without smartphones), smartcards or matrix cards are used instead.
Implementation of a custom MFA stage mapping the challenge-response logic of your physical tokens.
Development with Foresight
Update-safe, scalable, and secure – why you should trust us with your development.
Update-safe (No Core Hacking)
We don't modify the open-source software's source code. Instead, we use official APIs and plugin architectures. Your installation remains updatable and maintainable.
Full-Stack Expertise
We understand not just the code, but the infrastructure beneath it. Our developers know how queries affect database performance and how to build scalable APIs.
Modern Tech Stack
We use modern, type-safe technologies: React, TypeScript, Node.js, Python, Go. Plus PostgreSQL, Redis, and Docker/Kubernetes for infrastructure.
Security by Design
Every line of code is written with security in mind. Input sanitization, secure authentication (OAuth2/OIDC), and compliance with data protection regulations are standard.
Our Tech Stack
How We Work
From requirements to go-live – transparent and structured.
Analysis
We review API documentation, analyze your requirements, and identify optimal integration points.
Architecture
We design the solution: middleware, plugin, or script. Data flows, interfaces, and security concept are defined.
Development
Agile implementation with code reviews, automated tests, and continuous coordination. You see progress in real-time.
Deployment
Integration into your CI/CD pipeline or hosting on our infrastructure. Documentation and training included.
