PeerGuardian is a privacy oriented firewall application. It blocks connections to and from hosts specified in huge blocklists (thousands or millions of IP ranges). Its origin seeds in targeting aggressive IPs while you use P2P.

PeerGuardian Linux:
Actively developed. However the team is very small and with few spare time. Contributors are welcome!

Peerguardian OS X:
Not developed anymore. We've lost contact with the OS X developer. New contributors are welcome!

PeerGuardian Windows:
Not developed anymore. It's highly recommended to use PeerBlock instead, which is a continuation of PeerGuardian's development in Windows, with bug fixes and support for Windows Vista and Windows 7.
New contributors and/or collaboration with peerblock.com are welcome!

PeerGuardian is an open project. Not only is its source code open for you to read, use, and modify - but the project is open for you to join and contribute in any form (code, documentation, bug reports, web and support).

User Reviews

  • I like PeerGuardian, Superb software.

  • I don't get how Linux development is continuing but OSX development is not? Come on! The lastest osx version is a joke. It's one big heap of memory leak trash. Every second it just leaks, it uses more and more memory until after a couple of hours or so all the memory on your system is used up. OSX users are screwed.

  • Don't like the interface of program. Not user-friendly.
