How Does the Simplewall Firewall Work?

Simplewall Download free works by monitoring all incoming and outgoing traffic on your PC and filtering it based on an allow/deny philosophy.

As network packets attempt to either enter or exit your system, Simplewall intercepts them and checks against its configured rules and policies. It will then either block dangerous or unwanted traffic, or allow safe traffic to pass through.

Rules can filter traffic based on parameters like the application involved, IP address, protocol, port number and so on. For example, you can set a rule blocking a torrent program from making outbound connections, while allowing your web browser unfettered access.

The firewall runs quietly in the background, requiring no interaction while providing silent protection. You can however access extensive logging and connection data when desired.
