2025 Conference Recap

Another FIRST conference has come and gone, so let’s take a moment to relive it together! Held in beautiful Copenhagen, Denmark, FIRSTCON25: Fortresses of the Future – Building Bridges, Not Walls gathered 1056 security professionals from 103 nations for six days of insight, inspiration, and infectious energy.

With 523 FIRST team members onsite—including 34 liaison members and over 300 member organizations—the global incident response community was out in full force. Even more exciting: over half the attendees were first-time FIRST participants!

At its core, the FIRST Conference is about coming together — building trust, sharing knowledge, exchanging tools, and forming relationships that make the global incident response community stronger together. Connection drives us forward, helping us to create a safer internet for all in our delightfully small world.

Conference week gave us three thought-provoking keynotes, 113 speakers sharing cutting-edge insights, 8 Sunday trainers, a selection of BoFs and SIG meetups, and another fiercely friendly annual football match!

Copenhagen graced us with long days of sunlight and surprisingly good weather, perfect for networking walks, terrace conversations, and unforgettable moments. The Wednesday night social had us partying like Vikings well into the night (an hour longer than planned!), Masato-san’s smile infected us all over again, and Enrico’s elusive reading glasses continued their world tour.
