Earlier, Symantec Protection Engine had a URL filtering feature to block access to sites that contain unwanted content based on the categories. Symantec Protection Engine used Symantec RuleSpace URL categories and Child Abuse Image Content (CAIC) URL categories to scan and block the unwanted URLs.
Now, along with the above URL filtering features, Symantec Protection Engine 7.8 is also incorporated with the URL Reputation feature to block access to sites that contain malicious content like malware, fraud, phishing, and spam etc. URL Reputation feature assimilates Symantec’s DeepSight technology. The Symantec DeepSight identifies threats from domains and URLs, which could be hosting malicious content like malware, fraud, phishing, and spam etc. DeepSight-based URL Reputation feature allows you to block access to the web addresses that are identified as known sources of the malicious content.
The attached PDF document explains how to use DeepSight-based URL Reputation feature in Symantec Protection Engine 7.8.
