Michael Coates, Twitter's chief information security officer who joined in 2015, is leaving the company, as The Verge first reported and the company has confirmed to Axios.
Why it matters: Coates's departure comes just a couple of days after the NY Times reported that Facebook's security chief is on his way out later this year. But Coates appears to be leaving to start his own company.
