The Verge is reporting Twitter’s CISO, Michael Coates, is leaving the company to create his own security startup:

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. Coates confirmed the move Wednesday afternoon.

News of Coates’ departure comes on the same day that Michael Zalewski, director of information security engineering at Google, announced his departure from that company after 11 years. (Zalewski was a high-ranking security executive at Google but not its chief security officer; that role belongs to Gerhard Eschelbeck, vice president of security engineering.) not And it comes two days after reports that Alex Stamos, Facebook’s chief security officer, 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.

There are a lot of high-level security executives leaving larger Silicon Valley companies as of late. I think of the three – Google, Facebook, and Twitter – the latter has the most interesting sounding set of challenges.

If you are a security professional interested in a new opportunity, the Twitter gig would definitely be worth looking into.

Kara Swisher of re/code on recent acquisition discussions between Twitter and Flipboard:

Twitter has been engaged in an ongoing series of talks to acquire Flipboard, according to multiple sources with knowledge of the situation, in an all-stock deal that would value the company at over $1 billion.

Those discussions, which have been pushed by Twitter CFO Anthony Noto, have been taking place since the beginning of the year, said sources, as the social communications giant has faced increasing pressure from Wall Street to grow its audience and innovate its products. But despite a flurry of activity more recently, sources said these talks between Twitter and Flipboard — who are partners on a number of different fronts — seem to be currently stalled.

Still, the concept behind the acquisition are intriguing on all kinds of levels. For Twitter, it would bring an experienced product team — headed by well-known Silicon Valley entrepreneur Mike McCue — to the company.

I love Twitter and love Zite – which was recently acquired by Flipboard – so it will be interesting if this marriage is consummated, and if so, what will become of it.

Twitter desperately needs solid leadership who understands the company, actually drinks their own kool-aid, and is capable of coming up with inventive means of monetizing the platform. It would also be nice to have a Twitter management team who comprehends the importance of third-party developers and tools, who will help push Twitter in areas the company never thought to go.
