Editors' reviewEvery now and then, a Net user wants extra privacy online, or to use a piece of software that's being blocked by a firewall. Proxifier helps with both of these tasks. In our tests, we successfully used a mail client behind a firewall that had Port 110--the conduit for the mail program's data -closed. The program also can unblock other applications, such as a browser, a P2P client, an FTP utility, or instant-messenging software. It can hide a Net user's IP address while she's surfing, and operate through a chain of SOCKS proxy servers for added privacy. The software also provides a good tool for monitoring bandwidth usage and network connections. Though it should be simple to configure for advanced users, it may be daunting to users who aren't familiar with the idea of proxy IP addresses and port numbers. It doesn't provide an automatically updated list of proxy servers to use on the Net, a feature we would expect in a program that costs this much. Nor can it automatically switch among proxies to find the fastest one available. Overall, Proxifier can be a valuable privacy tool, but it's not user-friendly enough to be recommended for most mainstream computer users.
Proxifier allows network applications that do not support working through proxy servers to operate through a SOCKS or HTTPS proxy and chains. Features include work with any Internet client through a proxy, improve network performance or ensure privacy, easy yet powerful UI with live data, and up to date with new technologies.
Other features include proxifier can process all outgoing TCP connections, full IPv6 support, tunnel IPv4 connections through IPv6 proxy and vice versa, SOCKS 4 and SOCKS 4A (hostnames support) with User ID authentication, HTTPS with Basic and NTLM authentication, proxy failure is transparent for the client application if redundancy is enabled, selected proxies in the chain can be enabled or disabled, convenient UI that allows chain creation and reordering with drag-and-drop, system DNS and DNS over proxy modes, automatic DNS mode detection, and proxification rules can be based on application names, IP addresses, hostnames, and port numbers.
