Email Defense System (EDS)
The Email Defense System (EDS), powered by Proofpoint, is Northwestern IT's system for scanning and filtering junk email, phishing attempts, viruses, and malicious high-risk attachments sent to the University community. EDS scans all incoming mail, deletes identifiable viruses and junk email, and quarantines other junk email before delivering messages to the University's central email server.
A Safer, More Manageable Inbox
Contaminated email attachments are the most common source of computer infections. With EDS filtering out most of these as well as junk email, Northwestern email recipients experience:
- Increased computer security
- Decreased junk email, allowing for easier email management
It is important to note that EDS is an automated process and does not monitor or read private email messages.
The Email Defense System provides improved scanning for attachments and URLs that may contain malware or phishing. As part of this process, Proofpoint rewrites hyperlinks in emails so websites can be checked for malicious activity before users access them.Please note that URL rewriting is an automated process. Proofpoint does not monitor or read email messages.
If users hover over a rewritten link, they will see https://urldefense.proofpoint.com/v2/url?= added to the beginning of the original link followed by a string of letters and numbers. If a URL containing phishing or malware is clicked, users will see a message that the web page was malicious and blocked. Legitimate sites should load with no delay.
