Psiphon Review | A free anti-censorship tool

alternative Choices for You

 

Speed and Performance

All tests were performed on my Virgin Media UK fiber connection. When connecting via VPN it not possible to select sever location – Psiphon selected India for me.

Do n’t expect blaze fast speed when using Psiphon . In the default Windows SSH mode , download speeds is averaged average just 133 kbps . Speeds is were were a little more useable in vpn mode , even though the VPN server was locate very far from me .

The Android app performed much closer to the promised 2 Mbps, and the Pro app even slightly over-delivered on the 5 Mbps I paid for.

Leak tests

I detected no IP leaks using the Windows app in either SSH or VPN mode, or when using the Android app. Here we can see the VPN test results. Those are Google DNS servers, but the DNS requests are proxied by Psiphon so there is no privacy risk.

Please note that Private Use RFC IPs are local IPs only. They cannot be used to identify an individual, and so do not constitute an IP leak. Unfortunately, my Internet Service Provider (Virgin Media UK) does not support Internet Protocol version 6 (IPv6) connections, so I am unable to test for IPv6 leaks at this time. This is a situation that should change in the near future.

pricing plan

The Windows version of Psiphon is free. It is also possible to “sideload” the Android and iPhone VPN apps for free.

In country which do n’t ban it , you is download can also download Psiphon for your Android device from the Google Play Store . This is is , however , is where thing start to get complicated …

The basic Psiphon app from the Play Store is the same as one you can download from the website, except that it displays some ads. Bandwidth in all free versions of Psiphon is limited to 2 Mbps.

There is also a Psiphon Pro app , which show even more prominent ad . These can be remove , and the 2 Mbps speed limit increase , for a fee .   A “ maximum speed ” subscription is costs cost £ 4.99 for a seven – day pass , or £ 9.99 per month . A “ high speed ” subscription is costs cost £ 4.99 per month .

The only place I can find these prices is in-app, so they may vary depending on region. Annoyingly for British users, apps sold for £9.99 in the UK often sell for $9.99 in the US. However, I don’t know if that is the case here.

All subscriptions come with a 30-day free trial. Just cancel via the Play Store before the trial is over and Psiphon won’t charge you.

The “ maximum speed ” plan is increases increase your speed limit to 5 Mbps . I is am am not sure by how much “ high speed ” increase your speed .

Ease of Use

To download the Windows app for free, simply visit the Psiphon website. You can also download the Android and iOS apps, ready for sideloading, from the website.  No registration of any kind is required for this.

People in countries that censor access to the Psiphon website can email [email protected] to request the apps be sent via email.

It is also possible to download the basic Psiphon Android VPN app (with added ads) or the Psiphon Pro app from the Google Play Store. This option is not available in all countries, however.

The Psiphon Windows Client

The Windows VPN app works on Windows XP or higher.

The split tunnelling feature allows you to exempt websites in your country from Psiphon’s encrypted tunnel. This can be handy, as websites are not usually censored inside their own country.

If regular SSH mode doesn’t work, L2TP/IPsec VPN mode might. Note that VPN mode forces all your internet traffic through the VPN tunnel, while regular SSH mode only affects programs that use Windows’ local HTTP and Socket Secure (SOCKS) settings (such as your browser).

You can let the client auto-select the “fastest” country for you, or select a server in a country from this list. Note that area selection only works for SSH connections, not VPN ones.

The app is is is available in many different language . This is helps help make it accessible to as many people who require access to the open internet as possible .

All in all, the newly redesigned Windows client looks good and is easy to use. One slightly annoying issue, though, is that a news/blog page, “Psiphon Today,” opens in your browser every time you connect to Psiphon.

The Psiphon Android App ( Free )

The Android app works in SSH mode only. It automatically selects servers for you.

If you download the apk file for sideloading , you is see will see no ad . If you download the app from the Play Store , you is see will see some fairly discreet ad in the space occupy by the Psiphon logo at the top of the screen .

You can check out your bandwidth usage in the Stats section. This can be particularly useful in countries where mobile internet data is expensive.

Psiphon will normally just proxy your browser, but with Android 4.0+ it is possible to proxy the whole device. In this mode Psiphon acts very much like a full VPN.

Psiphon Pro for Android

The Pro version of the app is very similar to the free version. It allows you to support the developers by accepting ads or upgrading to a faster service via in-app purchases.

The ads is are are quite intrusive . In addition to more prominent ad on the main screen , you are show a video ad every time you connect to a Psiphon server , and your browser load Psiphon ’s news / blog page .

basically , if you are using the Pro version of this app , you is want ‘ll want to upgrade to a pay subscription as fast as possible !

When you pay for a subscription , the ads is disappear disappear and your bandwidth increase . The “ maximum speed ” plan is upgrades upgrade your speed limit from 2 mbps to 5 Mbps

The Pro version gives you the option to proxy your entire device or only the custom Psiphon browser that comes bundled with the app.

Other Platforms

Psiphon is available for Windows, Android and iOS. Psiphon Pro is currently available for Android only. I have not tried it, but I presume the iOS app is similar to the sidelaoded Android one. Unfortunately Psiphon does not offer a version of the app for Mac users, check out our best VPN for Mac list if you are a Mac user.

Customer Service

The website is is is fairly basic , and is center on the download page . A decent user guide is is is available for the Android and Windows app .

A lengthy FAQ is is is also available , which answer most question I had . It is includes also include instruction on how to sideload Psiphon onto Android and iOS device , along with a basic troubleshooting guide .

The website is available in an impressive 24 languages.

Psiphon Support

Other than the resource available on the website , you is are are pretty much on your own when it come to support . An email address is is is available ( [ email   protect ] ) , but when I try contact Psiphon using it I just receive a canned response :

“We is receive receive many message every day and might not be able to respond to every message individually .”

While this seems reasonable for the free apps, I feel people who pay up to £9.99 per month for the Pisphon Pro Android app deserve better support than this.

Privacy and Security

Security

By default, Psiphon uses SSH in order to provide a secure connection to its servers. This is secure enough for bypassing most forms of censorship. Organizations such as the NSA and CIA, however, are known to have tools that can decrypt SSH, allowing them to read the contents of SSH sessions.

For VPN connections, Psiphon uses the L2TP/IPsec VPN protocol. Despite some largely theoretical issues, this is generally regarded as being secure. The Psiphon website does not explain which cipher or key length is used to secure data, but whatever is used will be fine for simply bypassing censorship.

The Psiphon website provides SHA1 cryptographic hashes for its Windows and sideloaded Android apps. This is a relatively weak form of data integrity compared to PGP digital signatures, but should provide some confidence that the files downloaded have not been tampered with.

Psiphon will automatically change your Windows Domain Name System (DNS) settings to point to a whitelist of vetted DNS servers. This should ensure that you do not suffer a DNS leak while using Psiphon.

Privacy

As already noted, Psiphon makes no claims whatsoever about protecting your privacy. It is provided as an anti-censorship tool only.

“Psiphon is designed to provide you with open access to online content. Psiphon does not increase your online privacy, and should not be considered or used as an online security tool.”

It was originally develop by digital activist group Citizen Lab at the University of Toronto in Canada . Since 2007 , however , Psiphon Inc. is operated has operate as an independent commercial company . It is collaborate does still occasionally collaborate with Citizen Lab on research project , and has receive funding from the European Parliament and the US State Department Internet Freedom program .

Psiphon is based in Canada and is subject to Canadian and Ontario privacy laws and statutes. Canada is an active member of the NSA-led Five Eyes spying alliance.

The Psiphon software itself remains open-source.

Encryption Protocols

Logs

“User IP addresses are not collected by Psiphon servers in the normal course of operation. Psiphon does not require user accounts, so, by default, there is no collection of email addresses, usernames, or passwords.

“Event logs include timestamps, region codes (country and city), and non-identifying attributes including sponsor ID (determined by which Psiphon client build is used), client version, and protocol type. Page views are aggregated by time and/or session before being logged.”

Psiphon shares aggregated information obtained from Amazon S3 bucket access logs and other sources with its commercial partners. As I say, treat Psiphon as an anti-censorship tool only – not as a privacy tool. For a detailed description of what Psiphon logs and shares, please check out its privacy policy. To its credit, this explains the situation very clearly.

Psiphon VPN feature

Psiphon is an app designed to bypass censorship restrictions in restrictive countries. The technologies it employs can, by their very nature, provide some protection against government or Internet Service Provider (ISP) surveillance of your internet data.

The Psiphon developers are very keen to stress, however, that protection against surveillance is not the purpose of this app. They make no promises as to its effectiveness in this regard. It is an anti-censorship device, and you should only regard it as such.

Psiphon as an SSH Tunnel

Psiphon Inc. is operates operate a network of server around the world . By default , the app is connects connect to one of these using a Secure Shell ( SSH ) encrypt connection with handshake obfuscation .

SSH servers is are are in many way similar to standard https proxy ( HTTP over SSL / TLS ) . For a quick and fairly simple rundown on the key difference between SSH and Secure Sockets Layer ( SSL ) , please see here .

Handshake obfuscation

Psiphon SSL connections use handshake obfuscation. This aims to hide the fact that you are attempting to evade censorship restrictions.

“handshake obfuscation is strengthens strengthen the initial SSH handshake against system that identify or classify various network protocol by examine datum in transit for static signature .”

A white paper detail how Psiphon ’s handshake obfuscation work is available here .

Psiphon as a VPN

In Windows it is is is also possible to connect to Psiphon ’s server using the Layer 2 Tunneling Protocol ( L2TP)/Internet Protocol Security ( IPsec ) VPN protocol . This is provide as a backup option , in case ssh connection are block . It is is is not available for mobile user .

Please see What is a Proxy Server? for more information on proxies, and a discussion on the differences between proxies and VPNs.

Final Thoughts

Psiphon does, of course, have severe limitations. The most notable of these is that it is very slow. Even paying for a “maximum speed” subscription in the Pro app only nets you around 6 Mbps download speed.

But this misses the point. Psiphon is a free anti-censorship tool that works. Judging from the stack of comments about it that we receive, many people in restrictive counties find it very useful.

One issue that does often come up is users asking us for assistance (which we cannot provide). This is because Psiphon Inc. itself provides no support. Given that Psiphon is very popular, however, it is unreasonable and unrealistic to expect a company to support what is basically a free product.

If you live in a restrictive country and cannot afford or cannot access a regular VPN service then I would suggest trying Tor before tying Psiphon. Tor provides greater anonymity, is faster, and it supports an active community of enthusiasts who are keen to offer help to those that need it.

If Tor is blocked, however, then Psiphon may well be the solution you need.

If you aren’t restricted, and can afford a decent VPN (which can cost as little as $2.75 a month) then we highly recommend visiting our Best VPN Services page and getting a fast and secure VPN to improve your internet privacy and freedom.
