Bill Pretty began his career in electronics in the early 80s with a small telecom startup company that eventually became a large multinational. He left there to pursue a career in commercial aviation in North Canada. From there he joined the Ontario Center for Microelectronics, a provincially funded research and development center. He left there for a career in the military as a civilian contractor at what was then called the Defense Research Establishment, Ottawa. That began a career that was to span the next 25 years, and continues today.

Over the years, Bill has acquired extensive knowledge in the field of technical security and started his own company in 2010. That company is called William Pretty Security Inc. and provides support in the form of research and development to various law enforcement and private security agencies.

While this is Bill's first book, he has published and presented a number of white papers on the subject of technical security. Bill was also a guest presenter for a number of years at the Western Canada Technical Conference, a law-enforcement-only conference held every year in Western Canada. A selection of these papers is available for download on his website.
