It is recommended that you should enable this feature for effective application and web filtering.

Clearing Cache

You can also use the Clear Cloud Cache function to delete all cached categorization information. Zenarmor (Sensei) caches the query results for better performance, and periodically checks for updates on the cached items.

Clearing the cache might come handy if you want some particular categorization change to get applied immediately.

Local Domain Exclusion

You can configure your local domain names to be excluded from being queried on Cloud Server. This might be handy if you see that your local domain is being categorized as Firstly Seen Sites.

tip

Domains entered here will match for all subdomains and FQDNs. For instance: Example.com will also cover sub.example.com and host.sub.example.com You don`t need to add each subdomain separately.

If you want to exclude your domain,

1. Enter this in the Local Domain Name to Exclude Cloud Queries field.
2. Click Save Changes at the end of the pane.
