You will be working as a part of an agile international team of top-class security professionals with a wide variety of skillsets, interests and specializations. As a member of the team, your work will involve performing manual security assessments for our clients in various industries, as well as helping them mitigate threats the right way. Instead of running scanners or selling security products, you will be exercising your hacker mindset and diving in deep to find and exploit those sweet remote code execution vulnerabilities and business logic flaws in places where no-one has even thought of looking before.

As an employer, we offer you a good working environment with a healthy work-life balance; opportunities for travelling abroad should you wish to do so; a lot of control over your projects and research; and finally, exciting opportunities and challenges you cannot find elsewhere: Penetration testing aeroplanes and cars, lockpicking ATMs, and social engineering into banks are a reality for us.
