Safe Links



We have implemented a new solution from Microsoft called Advanced Threat Protection (ATP) Safe Links to protect our users from malicious links received by email.  Safe Links re-writes links in your email message so that protection can be applied when you click the link.   If a link is deemed harmful, it will block access to that link.  This feature will protect users even if they are accessing the links from their mobile devices or when they are off of the University network.

How Do Safe Links Work?

For many email messages, you won’t immediately notice any changes.  The browser links will look like they normally do.  But if you hover your mouse over the link, you will see the address now points you to a address.

 Note: ATP Safe Links will not rewrite links for our own domains:

What Do Safe Links DO?


If Microsoft or The Cortland Information Security team find a link to be malicious, we can block users from getting to that link.  Even if the link is harmless when the message is first sent, a malicious agent could change the destination to contain harmful content (such as a login page to steal your credentials).  By using a Proxy address, the original link is checked at the time the user clicks it, to determine if anyone has reported it as suspicious.

If a URL is deemed suspicious  by Microsoft you may receive a warning like this:


If the Cortland Team has deemed a URL to be problematic, you may see a message like this:



Remember to only click links in messages sent by a reliable and verified source.  If the sender’s email address looks suspicious, or the message itself doesn’t look right, don’t click the link without checking with your local computer supporter, or Postmaster.  Safe Links provides extra protection, but does not guarantee that all links are safe.
