Curious by nature. Decisive in actions!

Cyber Seals is a security startup that operates in an eco system of IT companies each with its own expertise and focus. So although we are young we can leverage our network and have access to clients like Ahold, ING, NS and government agencies. Our projects are typically 3 to 6 month assignments and are challenging for each level of expertise.

We appreciate everybody is unique with his/her own talents. We don't look at age to determine experience. We believe in sharing. We trust each other. We aim for longterm relationships. And we stay connected.

Personal development

Aside from the time to slack, you can use your annual personal training budget to get OSCP, OSCE or GIAC GCTI certified or join us to Black Hat and DEF CON®.

Fun stuff

We have plenty of fun stuff around in the office like game consoles, a claw machine, VR glasses and a dart board to name a few. And if we don't have it ourselves we'll go out and have fun somewhere else!

All in all an awesome place to work with passion, explore with time for slacking, be free, laugh, learn, make mistakes, feel fuzzy and warm at home, stop worrying, find solutions to complex puzzles, make friends and eat delicious pizza with that stringy cheese that always looks so great in commercials.
