BSides Prague 2025: A Recap and Photos

April 6, 2025 1 min read

Take a look at the highlights from BSides Prague 2025, where cybersecurity experts came together for talks, demos, and hands-on activities.

BSides Prague has a special place in my heart, maybe because I had the chance to be part of the organizational team and help bring it to the city. This year, April 3–4, 2025, the event ran under the theme “Evolution to Revolution” (full schedule here), exploring how fast-moving technology and AI can turn small changes into big, disruptive shifts. The focus on staying secure, responsible, and sustainable as technology evolves really resonated with me personally.

Over 500 cybersecurity enthusiasts came together for two days packed with workshops, talks, and networking. ELLIO had a blast attending as a gold sponsor! From the two-day CTF and lively hallway chats to the fun after-party at a nearby pub, the energy was incredible.

A huge thank you to all the organizers and volunteers who made it happen. Can’t wait for next year! And if you’re passionate about cybersecurity, mark your calendars for BSides Prague 2026 - we’d love to see you there!
