Customers sometimes report that Web Gateway unexpectedly blocks a website because it is categorized as ‘Malicious’ and/or assigned a ‘High Risk’ reputation. Upon investigation, the results appear incorrect. A common cause to this behavior is that the website URL in question is actually “uncategorized” and Web Gateway’s behavior reflects the categorization and reputation of the website’s IP address. Below are some resources to assist in identifying and resolving this and other instances of miscategorization.
