Hi! My given name is Gordon Lyon, though I often go by Fyodor on the Internet. I run the Internet security resource sites Insecure.Org, Nmap.Org, SecLists.Org, and SecTools.Org. I also wrote and maintain the Nmap Security Scanner. These projects don't leave me much time to update vanity pages like this one, so you may find a more formal and up-to-date bio on my Wikipedia entry. For people who just came here looking for my email address, it is email@example.com.
In case it isn't obvious from my web sites, I am a hacker. The good kind. I enjoy tinkering with computers, exploring networks, pushing hardware and software to its limits, and especially open source programming. I have been developing and distributing the free Nmap Security Scanner since 1997. It scans your networks to determine what hosts are online, what services (web servers, mail servers, etc.) they are offering, what OS they are running, and more.
