Hello Hacker!

If anyone understands the nature of your work, it's us. Citadelo was founded in Slovakia at a time when the role of an ethical hacker was barely known in our region, and it was a completely new concept for companies. From the beginning, we aimed to create a place where ethical hacking would thrive, and where we could push the boundaries of what's possible on interesting projects.

And we've succeeded. Today, our international team consists of 26 ethical hacking geeks. Each year, we handle hundreds of projects ranging from classic penetration testing to social engineering and covert Red Teaming operations. That's not all. As market leaders, we educate through the media, participate in both domestic and international conferences, host Hackers' Meetups, and our lectures receive high ratings from students.

And now, we are looking for you. Another geek with hacker DNA coursing through your veins, just like us, for whom "Hackers on Your Side" is not just a slogan but a promise and commitment!

TomΓ‘Ε‘ ZaΕ₯ko, Founder and Board Member at Citadelo – Hackers on Your Side!
