Proofpoint logo

An additional feature in the Proofpoint email security solution called "URL Defense” is now enabled to further enhance the protection of emails delivered to your UT Southwestern inbox.

This is what URL Defense does:

  • If an email contains an external URL, it will be directed to Proofpoint’s platform.
  • Proofpoint will then verify if the website is malicious and, if so, prevent access.

If you hover over a link that has URL Defense enabled, you will notice the URL begins with “" Please note Proofpoint will not modify links used solely for internal purposes at UT Southwestern.
