Tallow: Transparent Tor for Windows

Tallow is a transparent Tor firewall and proxying solution for Windows. In a nutshell, when you run Tallow:

All traffic from your PC is transparently diverted through the Tor anonymity network. Programs do not need to be configured to use Tor.

traffic from your PC is transparently diverted through the Tor anonymity network. Programs do not need to be configured to use Tor. All non-Tor related traffic such as UDP is blocked. This includes DNS-traffic to help mitigate leaks.

Tallow is similar to running Tor as aunder Linux or MacOSX.

Tallow has several advantages. Firstly, all non-Tor traffic is blocked and prevented from leaving your PC. This stops certain kinds of leaks, such as the DNS leak problem. Secondly, Tallow is transparent. This means that your applications and programs will not be aware that traffic is been diverted via Tor. You can therefore use your preferred web browser, or any other program that connects via the Internet, with zero configuration. But beware! Unlike the TorBrowserBundle, Tallow does not make any attempt to anonymize content sent though the Tor network. This may include cookies or other information that can identify you. For this reason Tallow is not intended to be a complete strong anonymity solution by itself. See the warnings below.

Some uses of Tallow include:

Tor-ifying applications/programs that were never designed to use Tor. Since Tallow is transparent , the application will not be aware that traffic has been diverted via the Tor network.

Since Tallow is , the application will not be aware that traffic has been diverted via the Tor network. Filter Circumvention . If you just want to circumvent Internet filtering, and do not care so much about strong anonymity, then Tallow may be appropriate.

. If you just want to circumvent Internet filtering, and do not care so much about strong anonymity, then Tallow may be appropriate. Better-than-nothing-Tor. Even though Tallow by itself is not a strong anonymity solution, some Tor may still be better than no Tor at all.

To use Tallow: (1) first download and install Tallow from the links below, (2) start Tallow by double-clicking on the Tallow desktop icon, (3) the Tallow UI will appear, as shown below:

Warnings

Tallow is produced independently from the Tor anonymity software and carries no guarantee from The Tor Project about quality, suitability or anything else.

Tallow is not a complete strong anonymity solution.

Tallow makes no attempt to anonymize the content sent through the Tor network. This content may de-anonymize you. For example, logging into GMail via Tor will de-anonymize you, since you are the only person who knows the password to your account!

Tallow may contain bugs. Please send feedback or bug reports to Basil.
