Firewall Network Settings

This Article Applies to:

  • Avast Business CloudCare

Firewall is another major component of protection offered in Essential/Premium/Ultimate Business Security alongside the Active Protection Shields.

Firewall monitors all network traffic between devices and the outside world to protect you from unauthorized communication and intrusions. The two profiles you can assign to defined networks are:

  • Trusted (Private) — Provides a lower level of security (your device will be visible to other devices on that network)
  • Untrusted (Public) — Provides a higher level of security (your device will be hidden from other devices on that network)

We recommend you apply the Untrusted profile to all networks that are not your private network, such as when you connect to the Internet in a café or at an airport. Network profiles are one of the rule matching attributes, meaning rules for trusted profiles are not active when connected to a network classified as untrusted and vice versa. Rules can be set to apply to either one profile or both.

In the CloudCare Portal, there is an option to Allow the end user to override the default profile for undefined networks. Ticking this checkbox would allow each end user to configure their own network profiles and defined networks.

Once this setting is enabled and saved in the Policy, wait approximately 5 minutes for the change to be propagated and reboot the device.

You can manually define various networks as long as you have the MAC address of the router(s), ensuring they are always listed as Public or Private based on what you choose. Click Add Network, enter the network name, MAC address, and the profile, and click Add.
