For some tests, a proxy or VPN is needed to connect to our customers' test environments. If that's the case and only when the test requires that separate connection, you will see it below the test environment URL towards the top of the test overview page.

In this article, you'll find information how to connect to a proxy or VPN and what VPN tools you can use.


In a test, when a proxy is required to connect to the customer's website, all relevant information is displayed in the Access section on the test detail page: URL and port of our test IO proxy server as well as your credentials to connect to it.

The URL and port information is needed to set up the connection to our proxy server. Check out chapter Setup on how to set it up for your operating system and browser.

After setting up the proxy and trying to connect to a website via your browser, your browser will show a prompt and ask for your credentials (username and password).


Regarding our test IO proxy, please stick to the following rules:

  • The test IO proxy may only be used for customer projects; it is not for private use.

  • The test IO proxy may only be used for tests that require using a proxy. For all other tests, you must deactivate the test IO proxy before you start testing.


The proxy setup and operation are different depending on your operating system and browser.

A VPN (Virtual Private Network) is used to establish a secure connection between remote networks across the Internet, so you can access e.g. private company networks or websites that are only accessible from a specific country. In order to use a VPN, you need a special software tool that enables you to set up a connection to it.

Both for mobile and desktop environments, there are multiple apps and programs that you can use. You can download it to your mobile device or as a program for your desktop computer. There are also add-ons for common browsers like Firefox and Chrome.

Below, we present you a few tools – both free and fee-based – that you can use to set up a VPN connection for testing.


Tunnelbear is a free app available for mobile and desktop environments. After opening the app, you can see a virtual map with different tunnel exits in different countries. You have the possibility to select one of the available countries and to then establish a connection to the respective server in the chosen country. In the free version of the app, you get a certain free amount of data volume per month; usually 2 GB. For paid users, this limit is removed.


ExpressVPN is a fee-based VPN software available both for mobile and desktop environments. There are different pricing models available starting from around 8 to 9 $ per month.

With ExpressVPN, you have access to over 100 cities in nearly 100 countries and can switch between servers unlimited.

Other tools:

  • NordVPN (fee-based)

  • Cisco AnyConnect VPN Secure Mobility Client (if you have VPN information but need a desktop program to connect to that VPN)
