CaTS has implemented an email protection program from Proofpoint called Targeted Attack Protection (TAP). TAP helps protect against emails that contain malicious URLs and attachments, and has been implemented as an enhancement to our existing spam filtering service.
On this page:
With TAP, all URLs in an email message are rewritten as "proofpoint.com" addresses. When a user clicks a URL in an email message, the URL is redirected to Proofpoint's URL validation service. If the URL is not known to be malicious, the user will be redirected to the original URL. If the URL is malicious, the user will see a warning message and the site is blocked in the browser.
When a malicious URL is clicked on, the image below will appear:
If you click a URL and believe that the site is being blocked in error, call the CaTS Help Desk at (937) 775-4827, or email firstname.lastname@example.org. The blocked URL will then be investigated further.
Along with TAP URL defense, CaTS has now implemented TAP Attachment Defense from Proofpoint. This system detects an email that contains a malicious attachment and strips the attachment to prevent phishing and targeted malware attacks. If you receive an email containing an infected attachment, Proofpoint will filter out the email to protect your account from being compromised. Please be aware that while the attachment is being analyzed for malicious content, there may be a delay in delivery of a few minutes.
This enhancement to TAP is being implemented to our existing spam filtering service. If you have questions about TAP, call the CaTS Help Desk at (937) 775-4827, or email email@example.com.
