Firewall protects a user's computer against network threats when browsing the internet or using a local network. Firewall blocks unauthorized network connections to the computer, thus reducing the risk of infection. Firewall also monitors network activity of applications on the client computer. This reduces the risk of malware propagation in the network, as well as restricts actions performed by users who violate, whether intentionally or not, the security policy adopted in the company.
On Windows devices connected to Kaspersky Next, Firewall is enabled by default; it is running under the settings recommended by Kaspersky experts. You can disable Firewall or edit its settings, if necessary.
