Why ProgCop?

In todays online world it's more important than ever before to take care of your privacy. Many applications are making outbound connections from your computer without you knowing anything about it. They collect telemetry information and send it back to the creator of the application. With ProgCop you can decide what processes can connect to the Internet from your computer.

How ProgCop works?

ProgCop uses Windows Firewall API to block outbound connections for applications. Because ProgCop uses builtin Windows APIs no kernel level drivers are needed which keeps your system stable. ProgCop is meant to be used together with the built-in Windows Firewall to block outbound connections.

Note that ProgCop needs admin priviledges to run (because it's using Windows Firewall API). When starting ProgCop it will ask for the permissions.
