Some people consider me an IT Security Guru with almost 20 years of experience in the IT industry. However I say, you always have to learn new things!

Prior to setting up Cyber 51 in 2009, I was already regularly teaching Penetration Testing Training Courses, Cisco authorized Security Courses and was regularly engaged by governments and other businesses to establish Security policies, perform Ethical Hacking and Penetration Tests in order to secure network infrastructures and to remediate the threats encountered.

I provided IT Security Services as a consultant to organizations such as the German Railways Group, Cable & Wireless, Hypo-Vereinsbank, Motorola, Fast Lane, Cisco Systems, Apple, the U.S. Army, the British Army and various other government bodies and private sector clients.

At Cyber 51, I provide Penetration Testing and Security Audit Services to clients around the globe. I am regular speaker at Security conferences and work with the press on giving people an insight into current IT Security issues. In July 2013 I have presented a live Hacking demonstration at a conference in Jamaica. Attendees included senior Jamaican government ministers as well as board members from leading Caribbean banks.

My IT Certifications include the Certified Ethical Hacker (C|EH), Offensive Security Certified Professional (OSCP), Offensive Security Wireless Professional (OSWP) and numerous Cisco Certifications such as the CCIE (CCIE #13708) and the CCNP Security. Additionally I am recognized by the U.S. National Security Agency (NSA) as an Information Systems Security (INFOSEC) Professional as outlined in the 4011 and 4013 U.S. Government Standards. I hold a Bachelors Degree in Computer Science from the Technical College in Munich, Germany.

I was born in Munich, Germany in 1974 where I also grew up, attended high school and college. Later l lived in the UK, Mexico and the U.S. I speak German, English and Spanish fluently.

Whennot working or reading IT Security magazines, I dedicate a lot of time to support animal shelters and organizations looking after the needs of children in Latin America. Ilove to travel the world, undertaking long mountain bike rides, playing with our Labrador and St. Bernard dogs for hours or simply hanging out with my friends and family.
