How to Test if Your VPN is Really SecureLast Updated by Thalia Oosthuizen on January 31, 2019
People want a VPN that is able to ensure the security and protection of their data. While some are happy to just trust that a VPN is doing its job, there are ways you can you test if the VPN you use is really protecting you.
When you setup your VPN, there is a possibility that an error has been made, especially if you were setting things up manually, meaning that your data could be leaked, exposing your IP address and personal information, even when connected to your VPN.
We are going to take a look at the various ways you can test if your VPN is really secure.
1 DNS Leak Test
The Domain Name System, or DNS, is used to offer easier access to sites by translating the domain names to the corresponding IP addresses. Normally, this is your Internet Service Providers (ISPs) job. But when you are using a VPN service, your real location is masked, preventing anyone from tracking you. Occasionally, the translation request leaks from your VPNs tunnel and your IP address and ISP location is exposed.
Running a DNS leak test is very simple as you only have to connect your VPN to any server outside your country and use a tool like DNS Leak Test to test whether you have a leak.
If the IP address the site finds matches your real location, then you’ll know that your DNS is leaking. To avoid a DNS leak, only use VPNs with their own encrypted DNS leak protection .

2 IP Address Leak Test
Most VPN services promise to keep your IP address private and protected. Sadly, the reality is somewhat different asa recent study found that 84% of Android VPNs leaked users’ IP addresses.
By using an IP leak tester, you are able check your VPN for leaks. You should also test it when you are reconnecting after a connection drop because any decent VPN will have a kill switch blocking all online traffic when it is disconnected.
3 P2P Torrent IP Address Leak Test
As VPNs are now more popular with P2P users, it has become vital to check that this specific security measure is on and working. Using a service such as ipleak will allow for you to check the torrent IP address and works similarly to a normal IP address leak test.
All you need to do is download the tests *.torrent file on the P2P client, open it and verify the IP information. If the information matches your real IP address and location, you aren’t secure.
4 WebRTC Leak Test
Mainly seen in browsers like Chrome, Opera, and Firefox that allow P2P sharing, WebRTC is an Application Programming Interface (API) which is an open-sourced tool that allows video and voice chats in the browser without any external extensions or plugins.
When an IP address leaks through a WebRTC API, it is called a WebRTC leak. By using sites like Perfect Privacy’s WebRTC test, you can test whether your VPN has one of these leaks.
If you have found a leak, simply disable the WebRTC in your browser to prevent further damage. For more information on repairing WebRTC leaks check out our guide here.
5 VPN Speed Test
As well as security and privacy, your VPNs speed is an essential aspect of its quality. There are many factors that influence your VPNs speed including but not limited to:
- Internet Service Provider (ISP) limitations
- Encryption levels
- Distance between your device and the server
- Number of users connected to the server
- Firewall settings
- Your device’s processing power
If you want to get an accurate reading of the affect your VPN has on your computer you’ll have to first run a speed test while the VPN is not turned off, and this will give the baseline speed. Once the test is complete, connect with the server of your choice and run the test again.
Compare the speeds to each other and you’ll be able to see the effect that the VPN has on your speed. As a general rule, the closer the VPN server is to your actual location, the faster your speed will be.
