Application filter

With application filter policies, you can control access to applications for users behind the firewall.

Policies specify access to application categories or individual applications using rules. The default set of policies includes some commonly used restrictions. You can also create custom policies according to the requirements of your organization.

In application filter policies, the web proxy detects applications that use HTTPS.

  • To add an application filter policy, click Add. When you add a policy, you can select any policy as a template. Then, after you save the policy, you can add or edit rules.
  • To edit a policy, find the policy you want to change and click Edit Edit button.
