Twitter's chief information security officer is leaving the company, sources familiar with the matter have told The Verge. Michael Coates, who joined the company in January 2015, is quitting to start his own company, sources said. Coates announced the move internally about three weeks ago, sources said, but had not announced the move externally.
Twitter declined to comment.
News of Coates' departure comes on the same day that Michael Zelewski, director of information security engineering at Google,plans to leave the company in August. The departures come at a time when tech companies are under mounting pressure to prevent their platforms from being misused by foreign governments and other bad actors ahead of the 2018 midterm elections.
At Twitter, Coates' interim replacement is Joseph Camilleri, a senior manager for information security and risk, sources said. Camilleri previously filled in for Coates last year when the latter was on paternity leave.
