Combining Web Category and URL Pre-Filtering settings
By default, URL scanning is done inside a VM. However, if performance is a concern, you can enable URL Pre-Filtering.
When URL Pre-Filtering is enabled, it will work together with the Scan Profile settings and Web Category settings.
Scenarios
URL Sandboxing Pre-Filtering is Enabled
- If the category or URL is Unrated, the URL will be scanned inside the VM.
- If the URLs category falls into one defined in the Scan Policy and Object > Web Category page, but is not selected as Default, a job will be created and the URL will be rated as Suspicious (Low Risk, Medium Risk or High Risk according to category).
- If the URLs category falls into one defined in the Scan Policy and Object > Web Category page, but is selected as Default, a job will be created and the URL will be rated as Clean and will not be scanned inside the VM.
URL Sandboxing Pre-Filtering is Disabled
In this case, all URLs will be scanned inside the VM.
