Less than 1 percent of emails sent during May from Gmail to Comcast were encrypted in transit, Google says. Microsoft and Comcast are apparently not on Google’s transparency report. Google has been encrypting all Gmail messages by default since 2010. Microsoft said late last year that it would be expanding encryption across its services, with plans to encrypt all of its key communications services by the end of 2014. An even stronger form of security is provided by “end-to-end” encryption, which encrypts data from the moment it leaves the browser.”]
