How to Ensure a Secure VPN Connection Step-by-Step

It’s the main goal of using a VPN service to protect your data, but how can you tell if it’s protecting you properly? Using a VPN is a multi-step process, so you can make mistakes that expose your IP address even when you’re connected to a VPN.

We will examine different tools in this article that can be used to check for leaks on your VPN connection of various types of VPN for Windows connections. You can find out whether your VPN is protecting you or not by running all the tests we listed.

Leakage of DNS information

A DNS is a domain name system. Translates domain names to their corresponding IP addresses so that web pages can be accessed. A valid IP address for is

In general cases, the work of doing this “translation” is carried out by your Internet Service Provider (ISP). However, using a VPN your real IP address is hidden, preventing others from tracking your location.

It is sometimes the case that these translation requests leak your IP address and location outside of the VPN tunnel. Using tools such as to test DNS leaks is as easy as connecting to a VPN from outside your country. IP address, location, and other details match the ISP’s, which indicates your DNS is leaking abroad.

The IP address of your ISP and the location of your ISP is filtered in DNS leaks, although these can be easily used to determine your IP address.

Utilize a VPN that provides DNS encryption to avoid DNS leaks

A leak of IP addresses was detected. Despite VPN promises of IP address protection, in practice, this may not be true. During a study of VPN apps for Android, it was observed that 84% of VPNs leak the user’s IP address. Our IP filtering test can help you determine whether your VPN service filters your IP address. 

During reconnection, it is necessary to check if the VPN service has IP address leaks while it is active as well. VPNs usually filter your IP address when you reconnect after a break in connectivity. In the event of a VPN disconnect, the VPN should have a kill switch, a kill switch that blocks all internet traffic if the VPN disconnects.

Checking the IP address filtering of a VPN during reconnection:

Connect and use your VPN while disconnecting from the internet. When the connection is down, reconnect and run several IP leak tests in quick succession. To do this, open multiple tabs and refresh the test tool web page quickly.

Your ISP’s limitations

Even the fastest VPN free won’t come close to the speed offered by your ISP, which controls the overall speed of your Internet connection.

The physical distance between a VPN client and the server

Speed is the most important aspect that affects the speed of a VPN. If you are in India using a VPN server located in the US, you will have slow internet speeds. It will be easier to avoid this problem if you choose a VPN service that has servers in your area.

Active VPN server users

Many VPN services have too many users on some of their servers, which slows down their speeds. If you plan to purchase a VPN, make sure you can see its current server status as well as the bandwidth data in real-time.

A firewall’s settings

To maintain good connection speeds, your firewall settings should not interfere with VPN traffic or CPU performance. You must follow all the guidelines to make your computer working with this best free VPN for Windows.

Power consumption of your device

The VPN encrypts and decrypts data packets constantly in the background as the data is transmitted, which consumes a lot of processing power. The higher the desired speed, the more processing power is needed.

This means that even if your VPN is fast and you have a good Internet connection, your CPU may be preventing you from enjoying higher speeds.
