What Is Proofpoint?

Proofpoint provides advanced threat protection for faculty and staff email accounts.   Along with anti-virus and anti-malware, Proofpoint scans attachments and links in emails and blocks them if they are found to be malicious.   Proofpoint is the replacement for O365 Advanced Threat Protection (ATP) and provides additional functionality, better protection, and faster scanning.


Attachment Scanning:

Proofpoint does not deliver the email until the attachment has been scanned, so you will no longer see the notice that it is scanning.  This should not delay delivery of your emails. Attachments will not be scanned on internal emails.  If you receive an email from another employee’s address or a scan from a printer/copier on campus, the attachment will not be scanned and will be delivered immediately.

Link Protection:

Links will continue to be rewritten so that, if you hover over it with your mouse, you will see a very long address instead of the address that the link will take you to. When Proofpoint rewrites a link it looks like this and begins with
proofpoint link URL


If the link is blocked, you will see this page:
proofpoint blocked link

Proofpoint will automatically pull emails with malicious links from mailboxes, so the email will probably disappear from your inbox shortly afterwards.  Internal links to webpages will not be rewritten. 


What you must continue to do to protect yourself and APSU:

No security tool is perfect and will never be able to protect against every malicious exploit. You should always be alert to emails that:

  • Create a sense of urgency.
  • Invoke strong emotions, like greed or fear.
  • Request sensitive data.
  • Contain links that do not match legitimate resources for the organization that is contacting you. All links are rewritten with Proofpoint to begin with the following:

 As always, if you are unsure if an email you’ve received is unsafe, contact the Help Desk (, 221-4357) or the IT Security Director (, 221-7113) for assistance. If you suspect that you may have compromised your account by clicking on a phishing email and either opening a malicious link or attachment, change your password immediately and contact the Help Desk for assistance.
