Encrypt your email for security

Some companies have started scanning the emails of their employees for security purposes. Though this is for good, it can also hamper other innocuous things like unofficial emails to friends from your office email id. Mobrien is a software that helps you to encrypt your email message. What you need to do is go to their website, and after you obtain a temporary password, click on the 'Send out an encrypted email' button. You shall then be taken to a new window where you can send an encrypted email. The receiver shall receive instructions on how to read the encrypted email. So, all along the email remains encrypted. I understand this would most often serve only malicious purposes, but felt that with so many softwares emerging to serve email encryption, I should review atleast one of those I know about.
