Configure Block and Allow List policy settings to define access to sites based on the domain or URL.
You must have enabled Web Control in the Options policy.
Log on to the ePO - On-prem server as an administrator.
From the Policy Catalog page, select Endpoint Security Web Control as the product, then select Block and Allow List as the category.
Click New Policy.
On the Create a New Policy dialog box, type a name and description for the policy.
On the Policy Catalog page, click the policy that you created.
Click Show Advanced.
On the Block and Allow List tab, define these settings:
Add — Add sites to the Block and Allow List. You can enter URLs or partial URLs (site patterns) of at least three characters. For multiple sites, enter a comma-separated list or enter each site on a separate line.
Delete — Delete sites from the Block and Allow List.
Edit — Change information (URL, site pattern, or comment) for a site.
Search — Search the Block and Allow List. This feature is useful for finding sites in large lists.
Test Pattern — Test whether specific sites match the patterns in the Block and Allow List.
Enable allowed sites to take precedence over blocked sites — By default, when a site is set to both Allow and Block, the block action takes precedence and the site is blocked. Select this option to override the default behavior and make sure that users can access allowed sites, even if they are also blocked.
Caution
When selecting this option, make sure that allowed sites are safe so that client systems remain protected from web-based threats.
Click Save.
