Wil Allsopp always liked taking things apart. Sometimes he was able to put them back together again. He wandered into penetration testing like some people wander into bars (another activity close to his heart). A chance encounter with a like-minded individual in the 't Stadscafe Zaltbommel in 1999 led to him resigning his IBM software development contract and forming his first company, called Tigerteam Security NV, which for reasons lost to time was incorporated in Curaçao. At least that's how he remembers it.

Nearly 20 years later, he's still breaking things, with the important difference that some of the most prestigious companies in the world are paying him to do so.

He lives in The Netherlands with his wife and a large menagerie of cats, dogs, chickens, and a toad named Malcolm.
