For some tests, a proxy or VPN is needed to connect to our customers' test environments. If that's the case, you will see it right at the top of the test overview page underneath the test environment URL.

In this article, you'll find information how to connect to both a proxy or VPN.


Connection information

If your test requires you to connect to our test IO proxy, a URL and a port will be displayed below the test environment URL. Enter them in your operating system or browser as described in the next section “Setup” below.

After setting up the proxy and trying to connect to a website via your browser, your browser will show a prompt and ask for a username and password. Enter the credentials that will be provided directly in the test instructions under Access.

You will find this information only for the tests where configuring Proxy is one of the requirements.


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

  • Google Chrome
  • Mozilla Firefox
  • Microsoft Edge
  • Microsoft Internet Explorer
  • Android: Go to Settings > WiFi > long tap on your wifi connection > tap on “modify network config” > select the checkbox “show advanced options” > change proxy to manual
  • iOS: Go to Settings > Wi-Fi > touch the i-icon of your wifi connection > scroll down > set the HTTP proxy on manual


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)
