Portable PeerGuardian

Portable PeerGuardian is a lightweight Windows utility that makes sure your sensitive information remains private by blocking harmful IPs that may connect to your computer. It was specifically built for offering you protection against unauthorized connections.

Since this is the portable version of the program, it is important to mention that it doesn’t leave any traces in the Windows Registry. You can copy it on any USB flash drive or other devices, and take it with you whenever you need to protect your personal data from unauthorized viewing.

As soon as you run the program, you are required to select the organizations or servers to be blocked while surfing on the Internet or sharing files, namely P2P, advertising and data tracker servers, spyware and adware, known government addresses, and educational institutions and universities.

Plus, you can allow HTTP connections even if they are in the block list, import or create custom lists with servers to be blocked, as well as make the program automatically check for updates at a specified time interval.

Portable PeerGuardian boasts a clean and simple interface that provides information about the allowed and blocked IPs. It is possible to disable or enable the protection, and view a history section with details about the entire blocking process.

Other important features worth mentioning enable users to check out a log, pick the color for the background and text messages, archive the information about the allowed connections, as well as enable notifications for HTTP or all types of blocks.

Portable PeerGuardian proves to be a reliable firewall application when it comes to detecting and closing IP connections quickly and efficiently.
