Google Is Now Always Using TLS/SSL for Gmail Connections

Dan York
By Dan YorkDirector, Online Content

Gmail logoWe were pleased today to read that Google is now changing their Gmail service to always use TLS-encrypted connections. As they note in their announcement blog post:

Starting today, Gmail will always use an encrypted HTTPS connection when you check or send email. Gmail has supported HTTPS since the day it launched, and in 2010 we made HTTPS the default. Today’s change means that no one can listen in on your messages as they go back and forth between you and Gmail’s servers—no matter if you’re using public WiFi or logging in from your computer, phone or tablet. 

The key point is the one I emphasized in bold in the text: attackers cannot listen in on your messages as they go between your mail client (which could be your web browser) and Gmail’s servers.   Obviously the messages could still be potentially viewed either on your client device or on Gmail’s servers… but this step is removing the ability for the messages to be viewed “on the wire”.

This is a great example of the kind of action we’d like to see to make communication over the Internet more secure- and why we launched our new “TLS for Applications” section of this site.  We want to encourage more application providers and developers to make the steps that Google has done here.

Kudos to the Google/Gmail team for taking this step!
