A little over a year ago I made the transition from external security consultant to internal offensive security engineer at Facebook. I went from a full time breaker to part time fixer. This talk is aimed at providing lessons learned and documenting the mindset changes I've made over the last year that I feel can be used by the industry as a whole. I've broken the lessons learned into three primary buckets; Red, Blue, and Purple and the talk will hopefully bring value to anyone working in their respective bucket or assist in their creation/continuing of purple teaming at their company.
