A client chooses to not block uncategorized websites.

When a client chooses not to block uncategorized websites, additional measures are necessary to maintain a level of protection.

A URL filtering profile with the action set to continue for unknown URL categories: By setting the action to continue, users will be prompted before accessing uncategorized websites, which provides an extra layer of caution and awareness, helping to mitigate risks associated with unknown sites.

A file blocking profile attached to security policy rules: This helps to reduce the risk of drive-by downloads by blocking potentially harmful file types from being downloaded when users visit uncategorized websites. This additional layer of security ensures that even if users access risky sites, the likelihood of malicious file downloads is minimized.
