Scouting report

Was CISO at Yahoo, where he objected to a government email-scanning programme, then CSO at Facebook through the investigation into foreign influence operations, leaving in 2018 over how much the company would disclose. Publicly challenged the NSA director on encryption backdoors, founded the Stanford Internet Observatory, and co-founded iSEC Partners and later Krebs Stamos Group.
