URL filtering

URL filtering obtains the reputation and category of URLs in incoming and 
outgoing messages to allow several new functionalities: 

Anti-spam and outbreak filters now use the reputation and category of URLs in 
messages to help determine if a message is spam or malicious. This additional 
data improves the filtering accuracy for messages that contain URLs. 

You can further reduce the threat from potentially malicious sites by modifying 
URLs in delivered messages. You can make URLs unclickable, replace them 
with text, or redirect them to a proxy that evaluates the safety of a site if and 
when the recipient clicks the link, and blocks transactions it deems unsafe. 

You can create content and message filters to modify URLs based on 
categories of URL that are likely to be problematic. 

You can configure mail policies to modify URLs found in suspected spam. 

You can create content and message filters to enforce acceptable use policies 
based on the category of URLs in messages. For example, you can drop 
messages that include links in the Illegal Activities category.

Stochastic 
sampling 

From AsyncOS 8.5 for Email and later, if IronPort Anti-Spam or Intelligent 
Multi-Scan feature keys are active and SenderBase Network Participation is 
enabled, AsyncOS sends a random sample of messages to CASE for Antispam 
scanning, irrespective of their sender's SBRS. CASE scans these messages and uses 
the results to improve the efficacy of the product.
