The Notion of VPN. What Is It and Do You Really Need It?

Virtual Private Network, VPN allows you to establish a secure connection between your device and an external server. A VPN creates a private network over a public Internet connection, hiding your IP address. With this protocol, all your browsing data is sent through a secure, encrypted channel, allowing you to hide from surveillance and gain access to blocked resources.

A VPN is currently the best way to protect your device from hacking, DNS/IP address leaks, and ISP snooping. Despite the fact that the government may not approve the use of such services, when using a high-quality VPN with traffic encryption and no DNS leaks, no one will know about your actions.

At first, the VPN protocol was used by corporations to securely connect to remote offices. Whether you use a computer, tablet, or smartphone, you get more privacy when you use a VPN.

Several new VPN standards have been developed over the years, including L2TP/IPSec, S2TP, and OpenVPN. Of these, OpenVPN and S2TP provide the greatest security and data transfer speeds compared to others. That is why major VPN providers have begun to abandon the use of L2TP and PPTP standards as unreliable.

Currently, a new VPN protocol, WireGuard, is gaining more and more popularity. It could become available to all leading VPN providers by the end of this year. This protocol is characterized by high performance, ease of use and the use of modern cryptography.

How does a VPN work?

VPN uses a client-server architecture, with one important feature – the client’s identity cannot be deciphered. Imagine the Internet as a cloud. When you connect using any device, the VPN creates a secure tunnel through the cloud to one of the global servers, which takes care of all the tasks of providing traffic. Neither other users nor your ISP will be able to track your activities, since the most they can see is your connection to a remote server.

If you want to use the connection on a mobile device, then VPN providers usually provide separate apps for Android or iOS.

As a VPN user, you don’t have to worry about technical details. However, it is better to choose a provider with 256-bit traffic encryption than 128-bit, and it is also useful to check the connection for DNS leaks.

Why Use a VPN?

For privacy lovers, a VPN is the best way to protect yourself from government and ISP snooping. To be even more secure, you can try using browsers and virtual machines. At the same time, a VPN allows you to access many foreign services, and also makes it possible to bypass blocking.

The use of a VPN in the modern world is not only justified, but often necessary.
