Anonymize Your Web Traffic with JanusPA

December 24, 2008 · 18 comments

The in-the-works Janus Privacy Adapter is, hands down, the coolest piece of networking hardware I’ve seen (via hackaday) all year. The so-called Privacy Adapter has two RJ45 ethernet jacks and is intended to be placed in-line between your computer and Internet connection. After plugged in and given around 60 seconds to fire up, it anonymizes your web traffic through your choice of the Tor network or OpenVPN.

Janus Privacy Adapter for Tor and OpenVPN

Tor 101

Those of you all too familiar with this blog will remember the Tor network from my post that detailed how to setup Tor with the BitTorrent utility Azureus. In a nutshell:

Tor protects you by bouncing your communications around a distributed network of relays run by volunteers all around the world: it prevents somebody watching your Internet connection from learning what sites you visit, and it prevents the sites you visit from learning your physical location.

The long-standing problems with Tor are two-fold. For one, it depends on volunteers to host exit nodes and historically speaking, the Tor network is generally very slow from relying on nodes run on mediocre Cable/DSL lines. Also, Tor is not 100% secure for some value of secure. Exit nodes can be monitored and data can be harvested about users.. but the Tor network is about anonymity not privacy. Motivated people monitoring exit nodes (much like using an SSH tunnel and then just monitoring the remote computer’s traffic, if you can find it) may discover unencrypted user data but not know who that data belongs to. That reminds me of when AOL leaked search queries and people were able to determine patterns and find out personal information, but I digress.

The biggest pain is setting up the Tor network with every software application that connects to the Internet. If you’re not careful and leave a few applications unconfigured, you can leak out DNS lookups and easily provide potential snoopers data about your web browsing habits. If you’ve tried to follow my Tor + Azureus post, you know that setting up Tor and its required software is a huge annoyance and you can’t be entirely sure that your IP won’t leak through with a faulty configuration.

The Janus Solution

JanusPA seeks to put an end to the Tor software configuration issue with their hardware creation. There’s not software to configure, just plug it in and it routes your web traffic through the Tor network, or viable alternative OpenVPN.

Your real IP will never leak through this, regardless of the application you are using!

When released, the JanusPA won’t be cheap. Just taking a look at the parts that comprise it, it seems like a final version would be in the $200+ dollar range. Some might like to stick to a cheaper SSH tunnel route as I often use when traveling and using untrusted networks, especially since I can’t always count on finding an ethernet line instead of Wi-Fi.

Regardless of any drawbacks discussed here, this JanusPA would be warmly welcomed in my arsenal of gadgets. Now to see if this can’t be paired to a small Wi-Fi access point.

Janus Privacy Adapter: Useful, cool concept or expensive gadget for the paranoid? Would you buy one?

Looks like an awesome bit of kit. I live in China (although I’m from the UK) and constantly find myself having to fiddle with proxies, VPN’s and SSH tunnels to get around the restrictions here – this could be great time saver although as you mention not cheap. Something tells me they wont be selling this directly in China any time soon though :)

Nah I do not think I would buy one. I do agree that people should start surfing the web securely but I would rather do that through cheaper resources.

Definitely interested! Hope you review it when you get one.

I wouldn’t count on this being next years runaway success. Cool though.

might be popular in Australia depending on what happens to that legislation to monitor everyone’s traffic or whatever it was..

What’s the advantage of doing it in hardware instead of software?

It would depend.This is the easiest way to do it for a network of computers without client side setup. Another alternative would be to set up a server which does it for you.

Let’s say you’re having a meeting with dissident bloggers in your house in china, and you would like to provide a wireless network for them. The safe and easy way to do it would be to patch one one these between you router and acces point.

Instant anonymity.

Haven’t heard anyone talk about Janus in a while- if you’re interested in running a software version of this on your local machine you can find JanusVM in VMWare’s Virtual Appliance Marketplace (http://www.vmware.com/appliances/directory/392). I haven’t used it in nearly 2 years, and do not recall if it supports OpenVPN as well.

If you have VMware, they have an appliance which does something similar. Check it out http://www.janusvm.com/

Seems interesting, but I don’t really think that I would need that kind of privacy. Maybe this could be a hit in a few years though if governments start monitoring communications more stringently? This could capture the interest of a considerable slice of P2P users….

I like the idea, but I don’t think I would use it much. I secure my connection, but I don’t do anything bad enough to need something of this nature, it is a pretty good idea to keep the government big brother out of your life!

i would love to purchase one of these to plug in between my router and cable modem so all WAN traffic is “private” it would also be great for traveling! I will watch developments eagerly, thanks for the heads up Paul!

Such devices are certainly extremely useful. I hope we will, some day, see them as a BTO option in some machines, preferably laptops or notebooks. Of course, given the little incentive there is for business to help users safeguard their anonymity, this is most certainly wishful thinking…

I don’t think it’s quite useful; for traffic like SMTP, the Tor network blocks it, so you wouldn’t be able to send any email, download any Torrents, or whatever.

JanusPA is now selling. The website has been updated. I would recommend reading the FAQ, it’s very informative as to what it can be used for and how to use it. It does work with torrents BTW….

Just to sum it, you can use it for a single PC or a whole network. The choice is yours.

I’d like to order one to Germany – but of course anonymously! Any idea how to do this? Are there are retailers/shops?
