One of the things that we have noticed in the last few years is that the migration to the cloud has created a huge gap created by the migration to the cloud by Universities and Colleges.

Despite the rise of tools like Slack, Skype or Jabber the reality is that nearly all business communication between companies is over email. When your mail server is compromised and goes offline, not only internal communications will be disrupted, but external ones as well.

By the time any business is aware that they are the target of a ransomware attack, it’s too late. Once a hacker has breached security and enticed a user to click on a malicious link or attachment, access to local data on that employee’s computer is locked. In order to unlock the data, a ransom must be paid.

We are making two new changes to the way that the email system processes mail in an attempt to cut down on spam. We are adding additional validations and checks to ensure that the domains mentioned in the SMTP envelope are valid and have a functional DNS record.
