From the Wall Street Journal, but there were lots of other reports. The Chamber had at least six weeks worth of email data containing sensitive information stolen in a breach that was widely reported

These are various gateway appliances that operate inside your firewall, and automatically work in the background to encrypt and decrypt message traffic in conjunction with your mail servers. These are somewhat cumbersome but offer the following features
This is Mimecast’s Outlook plug in, and as you can see, there isn’t much to set up with it.
