The Purple Book Community started out as a project by 30 security leaders to author a book that captured best practices, case studies, and AppSec concerns. After the book was finished, everyone wanted to stay together and the Purple Book Community was born. The goal of the community is to enable organizations on their journey to AppSec maturity. To do so, the community holds live meetings 2x a month, creates blogs and podcasts, and hosts an annual conference called AppSecCon, where thousands of people from 20+ countries come together to participate in sessions over two days.
