What is a hackathon? 
It’s an intense three-day innovation marathon where teams tackle real-world cybersecurity challenges, from IoT vulnerabilities to AI-driven attacks and critical infrastructure protection. Bring your ideas, build prototypes, and present your solutions to an expert jury. 

How can you participate? 
Join individually and we’ll place you in a diverse team or register with your own team. We look for a mix of skills: technical expertise (programming, AI, cybersecurity), strategic thinking (project management, business planning), and creative vision (design, communication). 

What to expect: 

  • Hybrid participation: attend on-site in Budapest or join online;  
  • Intense and very dynamic experience: three days of brainstorming, developing, and pitching; 
  • Teams will be working on developing their ideas throughout the entire event – even late into the night;
  • Mentor support: get guidance from industry experts;  
  • Networking: connect with international students, professionals, and future colleagues; 
  • Real impact: your solutions could help shape the future of Europe’s cybersecurity. 

Why join? 
Learn, grow, and have fun while turning your ideas into real projects. Be part of a Europe-wide initiative shaping the future of digital security.
