Not too long ago we were looking to install the best antiviruses to keep our devices safe. But with the increasingly upgraded security protocols in our computers and laptops, VPNs are becoming the new security measure for most of us.

Today, many different VPN service providers can help keep your online activities safe and enable you to access geo-restricted content worldwide. And at the heart of the underlying technology of virtual private networks are VPN protocols.

This guide will break down everything there is to know about VPN protocols. We'll explain what part they play in your security, connection speeds, and compatibility, and compare the main features of the most popular protocols to help you choose the best VPN protocol for you.

A VPN (Virtual Private Network) is a tool that protects your digital safety while browsing, traveling, and in any other situations where you use an internet connection. People rely on a VPN connection to secure their network, bypass geo-restrictions, and protect their data.

However, VPNs are not without their hurdles. After reading this article, you will understand why is your VPN not connecting, how to troubleshoot most VPN server connectivity problems, and how to fix them quickly.

Both VPN (virtual private network) and RDP (remote desktop protocol) are remote access technologies. You use an internet connection to access a computer that’s in a different location than yours and get the benefits as if you were using that computer.

There’s one key difference between a virtual private network and a remote desktop protocol – the level of control you get. A VPN server only provides you with internet traffic routing, encryption, and some other benefits. You continue using your machine for everything else.

Remote desktop protocol gives you access to the machine itself. You may get different levels of permissions (ranging from limited access to full administrative privileges), but in all cases you’ll get to control the machine itself to some extent.

Many people get a VPN (Virtual Private Network) app for one explicit reason – to be able to change their perceived IP address. Since lots of data, including geographical location, is tied to IP addresses, changing it through a VPN server will change your perceived locale as well.

While enhanced privacy is a great benefit you can get from changing IP addresses, picking the correct VPN server location will also let you view content that’s usually restricted to that country only.

There’s always more reasons one can have to change their IP address, however.

Today, a VPN (virtual private network) is definitely one of the best ways to safeguard your privacy online. To be able to do so, however, a VPN should first work properly. With companies and governments strengthening surveillance practices, and cyber threats growing fast in 2025, one of the things you must do is to test your VPN connection.

As long as your VPN only looks functioning while it is actually not, there’s a risk of exposing your data and sensitive information without you even realizing it.

With a strong commitment to privacy and transparency, CometVPN works with a mission to make sure that your browsing remains properly secured. But even the best technologies need verification – and that’s where VPN testing comes into the scene.

In this post, we’ll walk you through the main methods of testing your VPN. By the end, you’ll have a clear grasp of what a VPN test is, how to run it properly, and how to sleep easily knowing your personal data is protected 24/7.

Once you get a quality VPN service, you want to use it everywhere - on your smartphone, laptop, TV, console, and all other devices. In such cases, it might be easier to install a VPN on your router than on each device separately.

The configuration varies by router model, but all newer ones support VPN clients. Once you set up a VPN on your router, all devices (even those that might not support it natively) are protected. If you're at least a bit tech-savvy, the instructions below shouldn't be too hard to follow.
