Creating an Internet Access Control Rule

Configure an internet access control rule to protect your users' internet access whether they are on or off your corporate network.

Note:

Trend Micro Vision One automatically creates a default rule to apply whenever no other internet access rules are matched. The default rule allows unrestricted access to the internet.

  1. On the Secure Access Rules screen, click the Internet Access Control tab and then click Create Rule.

    The rule configuration screen appears with the Web access control rule template selected.

  2. Specify a unique name and a description for the rule.
  3. (Optional) To enable or disable the rule, click the toggle next to Status.
    Tip:

    You can also enable or disable rules on the Internet Access Control tab.

  4. Configure the following rule factors.

    Locations

    Specify Internet Access Gateways, corporate network locations, or public/home network locations with specified IP addresses or geographic region.

Corporate network locations access the internet through a specified Internet Access Gateway. You can add corporate network locations from the Internet Access Control tab.
