I don't know Alex directly. I've worked in security a long time in various positions. Watch his recent talk: https://www.youtube.com/watch?v=-1kZMn1RueI https://www.youtube.com/watch?v=-1kZMn1RueI 0) Highly Technical Past. https://www.blackhat.com/presentations/bh-jp-06/BH-JP-06-Stamos-Lackey.pdf https://www.blackhat.com/presentations/bh-jp-06/BH-JP-06-Sta... < This is part of the problem space every app dev team has. 1) Great handle on technical realities and where things are going. 2) Great, clear, entertaining speaking style. 3) Articulate social media presence. 4) Doesn't come off as a security asshole. Most companies realize they should have security at this point. Getting there is another matter. Delivering the culture and attracting the right hires from a incredibly finite talent pool is the difference in the ability to execute. From what I've seen, his style wins over even the non-security people and he knows the technical better than most "Senior" security people. I suspect he'll have no problems filling his roles at Facebook.
