Proxifier 4.14 for Windows

Proxifier 4.14 is a Windows program from VentoByte SL that makes other applications connect through a proxy server, including those that have no proxy settings of their own. You define rules for which programs or addresses go through which proxy, and Proxifier handles the rest. It is a paid program with a trial; you can download Proxifier for Windows from proxifier.com.

Who Proxifier is for

Proxifier solves a narrow but real problem. Many programs, especially older business software, database tools, games and command-line utilities, simply ignore proxy settings. In a company network where every connection to the internet must pass through a proxy, such programs do not work. Proxifier intercepts their connections at the network level and sends them through the proxy you specify, so the program works without being changed. Developers use it to route only a test application through a debugging proxy, administrators use it to give a single tool access through a gateway, and people who work with several proxies use rules to decide which app goes where. It also resolves domain names through the proxy if required, which matters in closed networks. If you just want private browsing, a VPN service or the proxy settings of your browser are simpler choices.

System requirements

According to Proxifier's specifications:

• Windows (x86, x64, ARM): XP, Vista, 7, 8, 10, 11.
• Windows Server (x86, x64, ARM): 2003, 2008, 2012, 2016, 2019, 2022.
• 10 MB of free disk space; the installation pack is a single exe file of about 4 MB.
• Support for 32- and 64-bit applications.

Versions also exist for macOS and Android 8+. The package in the catalogue is about 5.24 MB according to catalogue data.

How to set it up

1. Download the installer from the official download page and install it.
2. Add your proxy server with its address, port, protocol and login details.
3. Use the built-in check to test the proxy.
4. Create rules: which applications or target hosts go through the proxy, which connect directly and which are blocked.
5. Watch the connection log to confirm that traffic goes where you expect.

Licence and safety

The catalogue lists the licence as a demo: the trial lets you test Proxifier before buying a licence on the official website. Use proxies you trust, since every connection routed through them can be observed by the proxy operator. Changes between versions are listed in the official changelog.

Pros and cons

• Pro: works with applications that have no proxy settings.
• Pro: flexible rules per program and per address.
• Pro: connection log for troubleshooting.
• Con: paid after the trial.
• Con: not a privacy tool by itself.

Alternatives

If what you need is a full VPN rather than per-app proxy rules, our listings include Proton VPN, Mullvad VPN, Windscribe VPN and OpenVPN Connect. v2rayN is a client for proxy protocols, and Radmin VPN and Hamachi create virtual local networks.
