About the Technical Reviewer

Since the early days of Commodore PET and VIC-20, technology has been a constant companion (and sometimes an obsession!) to Cliff Janzen. Cliff is grateful to have had the opportunity to work with and learn from some of the best people in the industry, including Malcolm and the fine people at No Starch. Cliff spends a majority of the work day managing and mentoring a great team of security professionals, but strives to stay technically relevant by tackling everything from security policy reviews to penetration testing. He feels lucky to have a career that is also his favorite hobby and a wife who supports him.
