How Does Simplewall Work?

Simplewall monitors all incoming and outgoing network traffic on a Windows computer and allows or blocks connections based on configured rules.

The firewall runs as a Windows service in the background with a very small footprint so it does not drain system resources. Users can create custom rules to allow or block traffic for specific applications or IP addresses.

For example, you can set a rule to block the Spotify app from accessing the network. Simplewall will then automatically block any connections Spotify attempts to make. Rules can also be based on traffic direction, port, protocol and more.

The activity monitor shows network connections in real-time so you can see precisely how apps are accessing the network. All events are also logged for auditing.
