“Andrew Whitaker was an early professional penetration tester when most of his competition was practicing it more as an art than a science. He is one of the first pen testers to be able to test along all layers of the OSI model, attacking network appliances to web servers, and never relying on canned software alone to deliver outstanding results”  --Roger Grimes, Author, Security Columnist, Microsoft Corp.


“Andrew Whitaker can steal and erase your computer files, trace every keystroke you make and take a snapshot of your computer screen while you, none the wiser, wander the web.”  -- Diana Ransom, Wall Street Journal  


“Whitaker shared what he knew about us: The names of our family members, what they did for a living, their ages, and other information like the address of the house we recently sold. Could he use that information to get us to invite him into our office, by pretending to be a family friend or on some personal business? Absolutely.”  -Ben Worthen, Wall Street Journal


“[Penetration Testing and Network Defense] goes to great lengths to explain the various testing approaches that are used today and gives excellent insight into how a responsible penetration testing specialist executes his trade.” -Bruce Murphy, Vice President, World Wide Security Services, Cisco Systems
