Proofpoint: URL Defense Tool

This document explains how the the Proofpoint URL Defense tool protects members of the Rice community by blocking malicious web site links within Rice email messages.

Rice security technologies protect faculty, staff, and students from specific threats that are distributed via email, including phishing and targeted attack. These emails sent to our community try to trick people into disclosing their Rice network credentials. These messages and the websites they link to often look legitimate, even to the discerning eye, including the use of our own logos, valid email or URL addresses and other contact information.

Proofpoint's URL Defense protects you and Rice’s network resources by blocking access to malicious websites when clicking links from within emails. Links and certain other commonly clickable text in all email messages are evaluated using a variety of sophisticated techniques to determine the likelihood that they lead back to phishing or malware websites.

If links can't be definitively classified as safe when the message is received, the URL is rewritten so that clicking it will cause URL Defense to evaluate the linked website a second time. If the link is safe, you will be directed to the site. If it is malicious, you will be presented with a "Web Site Has Been Blocked" notification in your browser similar to the below:

You should delete the message. If you have questions, contact the OIT Help Desk.
