Research and education form another part of the business. Its staff publish technical findings and security tools, and its training draws on work in consultancy and research. The team includes authors associated with the Web Application and Mobile Application Hacker’s Handbook series. Courses cover application security and red-team techniques, delivered through classroom and online formats. These activities connect practical testing with the skills security Teams need to investigate weaknesses and improve their own systems.
