SSN protection coming to Catmail on May 22, 2019

Starting May 22, 2019, OIT will enable a feature in Catmail to help you identify sensitive data like Social Security numbers in outgoing email and reduce the risk of distributing that data. Although this new feature will block emails that contain SSNs in some instances, it is still your responsibility to handle sensitive data appropriately.

This change is part of a larger plan to improve the security of Ohio University’s communication tools.  

What to expect 

If you try to email an SSN to someone outside of Ohio University, that message will bounce with a security warning and instructions on how to report a false positive. In Outlook on the Web or Outlook for Windows, a Policy Tip will appear at the top of your window letting you know that your message appears to contain sensitive data. If you press Send, the message will be rejected. On Outlook for Mac and mobile apps, the Policy Tip will not appear, but the message still will be rejected if you try to send it.  

To report a false positive, forward the rejection email to the IT Service Desk for assistance.
