CAFEIN® — The Federated AI Platform for Secure, Scalable, and Collaborative Intelligence 

CAFEIN® is a CERN-developed federated AI platform enabling secure and collaborative machine learning across institutions, disciplines, and data domains. 

Originally designed to support predictive maintenance and anomaly detection in CERN’s particle accelerator systems, CAFEIN® has evolved into a production-grade, privacy-preserving AI infrastructure. Today, it empowers research and industry partners to co-develop trustworthy AI models while ensuring that sensitive or proprietary data never leaves its source. 

A Comprehensive Federated Learning Ecosystem 

CAFEIN® provides an end-to-end solution for federated AI development and deployment: 

  • Modular and extensible architecture — easily adaptable to various domains, from scientific research to healthcare and industrial analytics. 
  • Production-ready orchestration — supports large-scale, multi-site FL workflows with minimal overhead. 
  • Robust and secure networking layer — designed to resist data poisoning, model inversion, and other adversarial attacks. 
  • Dedicated secure parameter server — built to maintain integrity and confidentiality in federated training processes. 

From CERN Technology to Global Collaboration 

Built on CERN’s tradition of open, collaborative innovation, CAFEIN® now supports a growing ecosystem of internal CERN projects and external partners across Europe and beyond. 

Applications span multiple domains: 

  • Scientific computing and accelerator operations 
  • Healthcare and biomedical research (e.g. brain MRI anomaly detection, multi-pathology classification) 
  • Industrial monitoring and predictive maintenance 
  • Cross-institutional data science and AI collaboration 

Why CAFEIN® 

  • Privacy-first — raw data never leaves institutional boundaries. 
  • Trustworthy by design — secure encryption and advanced threat mitigation. 
  • Scalable and interoperable — connects heterogeneous systems and partners with ease. 
  • Accessible and adaptable — built for researchers, engineers, clinicians, and data scientists alike. 

Proven in production — deployed in active multi-site environments at CERN and partner institutions. .
