Keycloak Development & Integration
Keycloak is modular to the core. Almost every functionality is a replaceable provider. We use Java to implement these SPIs and adapt Keycloak exactly to your infrastructure.
User Storage SPI
The most important point: We don't necessarily migrate your users. We develop User Storage Providers allowing Keycloak to read users directly from your existing SQL DB, mainframe, or API - without duplication.
Event Listener SPI
Audit compliance requires gapless logs. We write Event Listeners that stream every login, error, and admin action to your SIEM (Splunk, ELK, Graylog) in real-time.
Custom Themes (Freemarker)
The standard login window is off-putting. We develop responsive, accessible themes (based on your CI/CD) that seamlessly integrate the login experience into your application.
Concrete Use Cases
How we implement Keycloak development in practice.
Federation with Legacy Systems
You have thousands of users in an old MySQL database of an EOL software that cannot be migrated.
A 'read-only' User Storage SPI connects the old DB. Keycloak authenticates against old hashes but issues modern OAuth2/OIDC tokens for new apps.
Passwordless Auth & Magic Links
B2C customers constantly forget passwords. The login process must be frictionless.
Implementation of a custom authentication flow that only asks for emails and sends magic links. Fully integrated into Keycloak core, secure, and audited.
Token Enrichment (Mappers)
Your application needs specific data in the JWT (e.g., tenant ID, cost center) not found in LDAP.
A Script Mapper (JavaScript) or Protocol Mapper (Java) loads this data from an external API during login and signs it into the access token.

“WZ-IT provided very competent support in implementing our server and virtualization infrastructure. As part of the project, a Proxmox-based virtualization environment was set up along with a virtual machine for our application systems. Additionally, a structured backup concept was implemented. A particular focus was on security: the setup of a VPN tunnel and the clean implementation of encryption and access concepts were professionally executed. The structured consulting as well as the reliable and swift implementation deserve special mention. We are very satisfied with the services provided and are happy to recommend WZ-IT.”

“We have had very good experiences with Mr. Wevelsiep and WZ-IT. The consultation was professional, clearly understandable, and at fair prices. The team not only implemented our requirements but also thought along and proactively. Instead of just processing individual tasks, they provided us with well-founded explanations that strengthened our own understanding. WZ-IT took a lot of pressure off us with their structured approach - that was exactly what we needed and is the reason why we keep coming back. (translated)”

I particularly appreciate the clear communication, transparent pricing, and the comprehensive expertise that both bring to the table. Even after the setup, they take care of the maintenance, which frees up my time enormously and allows me to focus on other important areas of my business - with the good feeling that our IT is in the best hands. I can recommend WZ-IT without reservation and look forward to continuing our collaboration! (translated)”
