Welcome

Zoom in to www.techzoom.net, the home of technical security information, research, and tools. This site was created back in 2003 to act as the home of the research, tools, and publications by Stefan Frei.

Security research and analysis is my passion and profession. Inspired by the problems surfaced during security assessment engagements and I wrote many tools, some of which I make available here as online network security tools. Results of my research of the vulnerability ecosystem, presented at BlackHat or academic conferences, are listed under publications.
