I recently had the opportunity to give a workshop at The Java Community - Devoxx Belgium 2025 🇧🇪, where I co-hosted a hands-on session with Willem Jan Glerum: "Building Secure AI Agents with Quarkus LangChain4j". Together, we explored how to build and secure AI agents, from setting up #Quarkus with #LangChain4j to implementing guardrails, defending against prompt injection, configuring authentication and authorization, and adding monitoring and audit logging. It was fantastic to see the interest in practical AI security and to hear thoughtful questions and having theoretical conversations with the participants. 🙌 Huge thanks to everyone who joined, to The Java Community - Devoxx for organizing such a top-tier event, and to Lunatech for their continued support. #DevoxxBelgium #AI #Security #AgenticAI
