User dosed not have admin rights, by default vpn software like psiphon.exe does not requires an admin rights, when user clicks on double click it will automatically start. May be i have to check for User account control on local system.

So you will need Application whitelisting GPO or a next gen endpoint like Carbon Black that will sit on the network in stealth mode, find all the executables and then you can allow the ones you need then put the endpoint into enforce mode

Here I used -dataRootDirectory because without this argument psiphon would create a folder named ca.psiphon.PsiphonTunnel.tunnel-core at current working directory every time it starts, this argument prevents it.

Is there a way in windows 10 , window firewall or any third-party program that can detect and block urls/links before it decide to open any browser . Here my issue, I was using a free vpn program call Psiphon and everytime I connect to a proxy it will open a link on my default browser. Im sure it happens to everyone who used Windows , for example whenever they uninstall a software succesfully , a website suddenly open up on their browser. The only crappy solution that I found is to use the Tab Close Gold extension , it still open the link but it auto close it in about 1 second then the it show the nearest tab. Just discover an old outdated solution , Browser Select , it presumably prompt you to choose which browser to open the url. is there anything similar usable now?

As I stated in a comment Windows doesn't seem to let you remove/set-none the default browser or HTTP/S protocol so what you're asking for Windows wasn't designed to do. All of these suggestions are just that, suggestions as I haven't tested them nor do I know if they will cause some issue so use at your own will.Option 1: Group Policy Default App Associations

Navigate to this setting: Computer Configuration\Administrative Templates\Windows Components\File Explorer\Set a default associations configuration file. Enable it & give it the path to the file we tweaked above.

Option 3: Use Group Policy Software Restriction Policy to block this POSSIBLYThis is complicated, but if the app uses a certain executable (unlikely, but possible) that triggers this action you can block the EXE from running. Basically you have to use some sniffer program (ex: sysinternals Process Explorer, Process Monitor) to find whats being run then block it. I've done this successfully with a free antivirus (AV) pop-up alerts to buy the subscription/full-program, but in that case they have a unique EXE that handled that so I blocked that separate EXE & the AV continued functioning

Yup my theory is correct , all I need is no official browser (IE disabled/removed) installed and a portable unofficial browser . Windows might not be happy with you not having Edge installed , but Im sure theres a hack out there that can remedy that . I myself using a superlite Windows 10 version with no update capabilities , so I dont have to worry about Edge keeps coming back . Opening links or html files will be a problem and some regular browser functionality will not work but I can live with that :) .

I work with a High School and some of the students are using Psiphon to get around our web filter. So I believe we were having a similar issue. We found that A third party managed firewall and web filter filled our needs better than closing so many ports that have important services running on them. We used iboss for our web filter and firewall and we were able to curtail the problem with Psiphon.

Psiphon can mount proxy HTTP/SOCKS via tunnels. All the traffic of this application will bypass the port TCP 80 by default. So you must to have a firewall capable to inspect your packets to see which packets are real HTTP packets and HTTP proxy packets.

To be Honest, with my experience using and testing Psiphon, As long as the user has any kind of internet, no matter the block (even if though), Psiphon seems to manage it's way in anyway. It's lightweight setup make you able to use on a flashdrive (so it doesn't need to be installed on the PC at all, just need to plug in thumbdrive) and versatility makes it very hard to block, even temporally. not to mention that if it even get a ping from any open sever, it automatically updates itself, makes a backup copy, and gets new sever list. The reason why it's like this is because, it's designed to allow you access even in a another country where blocks are really strict... Basically, you're trying to march though the jungle but, up against an army that specializes in guerrilla warfare...

Ok folks, so here it is. After fighting this monster for about 9 months, I finally figured out how to stop PSiphon from running on my computers. PSiphon is a standalone program, because it does not install itself to the computer, there are no hash's or certificates to manipulate. I finally google'd how to stop .exe files from running and low and behold there it was. You have to set up a GPO to prevent psiphon3.exe from running. You will create this rule under the user configuration\administrative templates\system\Don't run specified windows application. From here you can figure out the rest. Now I have tried to run it on the computer, from the website and from a drive stick and they all failed to run. Can't wait for morning to get here so I can implement this on the computers at work. Hope this helps.

I have managed to do this by blocking the file path of the temp exe it creates when connecting. This removes the ability to rename the original exe and it works again (or having duplicates in downloads, i.e. "Psiphon3 (1).exe").

Psiphon clients are current available for Windows and Android and connect to the Psiphon network through a variety of transport protocols. I asked the Psiphon folks how the protocol selection worked and received this response:

Both the Android and Windows clients automatically select the best transport protocol to use to connect to a Psiphon server. SSH is one of several protocols that the client may use. There is no user setting available to choose a specific transport protocol.

With the exception of VPN mode on Windows, Psiphon always uses SSH as the underlying transport protocol. Various different obfuscation techniques are layered on top of the standard SSH protocol. The client attempts to connect using all available methods, and chooses the fastest successful connection.

By default, the Windows client will connect in browser only mode and then launch the Psiphon browser with a Psiphon sponsor page loaded. This mode only tunnels traffic from the Psiphon browser through the Psiphon network.

This is an interesting feature. Psiphon notes that even in the most censored countries, sites within the country are usually not censored. Since it is generally slower to access the internet using Psiphon, you can enable this feature to split your regional traffic. Traffic destined for your home country will not go through Psiphon, instead travelling over your default ISP network.

Because you are connecting to Psiphon servers in other countries, and using obfuscation technologies, your connection can be slow. If the connection is too slow, then the Psiphon client may disconnect. Enabling this feature will prevent that from happening.

Psiphon will automatically set up an HTTP proxy which will work for most people. However, it may not use the same port every time. You may have applications on your computer that you want to use Psiphon with, which means it will need to send traffic over a specific port. You can set that up in this pane.

This setting should be named Use VPN. Enabling this setting will launch an L2TP/IPSec VPN connection to the Psiphon servers. The advantage of this is that it will tunnel all of the traffic on your computer through Psiphon instead of just web traffic. The downside is that a VPN is obvious so it is easy to block.

The reason for this difference is that the Psiphon browser is configured to use the Psiphon proxy whereas your default browser is not. Therefore, it is only safe to use the default browser if the entire device is being tunnelled through Psiphon.

This setting defaults to the Best performance option that allows Psiphon to select the fastest connection for you. However, you can override this by selecting any country. This setting works regardless of what mode Psiphon uses to connect.

This should be named Use VPN. When this is disabled, only the Psiphon browser is tunnelled through Psiphon. Enabling this option turns on a VPN that tunnels all of your traffic through the Psiphon network.

Pulling down the Android shade menu from the top of your phone while Psiphon is running will confirm what mode it is running in. If only the browser is using Psiphon it will show that it is running in browser-only mode.

This setting allows the addition of HTTP headers. While there are a myriad of uses for custom HTTP headers on the internet at large, I am not sure why the feature would be included in a censorship circumvention application.

Only one of these can be enabled. The first one will simply use any proxy settings that already exist in your phone. The second option enables the following settings to set up a proxy for Psiphon to use:

As it sounds, you can set a custom home page here or you can set the home page to a blank page. In other browsers the term home page means the page that will be loaded when the browser launches. That does not seem to be the case with the Psiphon browser. Regardless of the home page I entered, the Psiphon page loaded first. I had to manually press the Psiphon button to the left of the address bar and select Home page to get to my home page.
