Protection From Network Threats

Firewall protects your Mac from unauthorized access and prevents leaks of important data. Firewall allows you to control application connections to the internet and data transfer via the network and block suspicious connections.

Firewall is automatically enabled after you install and activate the Dr.Web license. The monitor launches at system startup and operates constantly in the background.

Firewall controls all incoming and outgoing traffic and allows or blocks application access to network resources according to the selected operation mode and specific filtering rules.

Enabling and disabling Firewall

Third-party applications for scanning web traffic and controlling access to web resources installed on your Mac may not work properly if Firewall is enabled.

Firewall doesn't work / System extension blocked

macOS 10.13 and later versions block kernel (system) extension loading. At that, Firewall doesn’t work, and you see a notification saying that the system extension was blocked. For protection from network threats to operate correctly, allow the loading of system software from Doctor Web Ltd.

Firewall blocked internet access

If an application (for example, a browser) can’t get access to the internet, create a new rule in the Firewall preferences.
