PeerGuardian 2 is Phoenix Labs’ premier IP blocker for Windows. PeerGuardian 2 integrates support for multiple lists, list editing, automatic updates, and blocking all of IPv4 (TCP, UDP, ICMP, etc), making it the safest and easiest way to protect your privacy on P2P.
Note: PeerGuardian 2 does not support Windows Vista at the moment. This is a top priority, and we hope to have a Vista download soon.
PeerGuardian 2 supports Windows 98, ME, 2000, XP, and 2003, in 32-bit and 64-bit.
Phoenix Labs and the PeerGuardian team do not condone copyright infringement. There are many legal uses of P2P and we are sick of being treated like criminals! We want to keep organizations and individuals from collecting data about us without our consent.
PeerGuardian 2 is Open Source, meaning the program code is available online for anyone who wants it. Not only does this allow you to make modifications or even branch off into your own project, but it encourages peer review of the code making sure any bugs are eliminated swiftly. Because PeerGuardian 2 is Open Source, you can rest assured there are no backdoors or spyware included.
