About Me

Martin Mielke

Penetration Tester, Content Developer & Researcher

I am able to draw on over ten years’ IT security experience, both as an Offensive Security Expert in the German Armed Forces and as a Senior Consultant in private practice.

I have built a track record of coordinating penetration testing and vulnerability assessments that deliver results for both public and private sector clients. My practical experience is underpinned by a strong and relevant professional education: I am OSCP, OSCE, OSWE, OSEP, CRTO and CISSP qualified, graduated with a First-Class degree in Computer Science and have completed an MSc in Applied IT Security.

When I’m not working, I try to learn new skills, write security tools, create content & participate in various CTF competitions.
