The Sophos Web Appliance does not allow you to block or allow sites in the Phishing and Fraud, Spam URLs or Spyware site categories on the:
- Configuration|Group Policy|Default Policy page
- Configuration|Group Policy|Special Hours page
- Configuration|Group Policy|Additional Policies page.
These site categories are grayed out because they contain URLs that are known to be malicious. Therefore, the Sophos Web Appliance does not allow administrators to grant access to these web sites.
