What is a VPN?

A VPN, or virtual private network, enables users to log in to a public network whilst still remaining secure on their own private network extension. Users are still able to receive and send data across a public network, but their privacy and security remains uncompromised.

How does it work?

A VPN connection uses encryption in order to allow users to log into a public internet service, but without the worry that your data can be seen by other users also on the same public network. In order to do this, a VPN service will hide your IP address, so nothing can be downloaded across the network that could link to your personal information or identity.

Setting up a VPN service is quick and easy to do anywhere there is public WiFi. To begin, simply start by making a DNS request. This allows you to access the IP address of the VPN server. This then creates secret keys and opens up a secure channel. Your connection should now be set up securely, with your VPN service fully encrypted.

There are a number of different VPN service options users can connect to. Here are just a few to consider

  • OpenVPN

This is great for long-distance connections is quick to set up and totally secure.

  • IKEv2

Ideal for short distances, this connection is also easy and secure for all your WiFi needs.

  • Wireguard

This VPN service is a newer protocol but still offers a good private connection.

Along with protecting your personal privacy and data, a VPN service is also a useful tool to help you browse otherwise blocked websites. As a VPN service conceals your location information, you can then access some websites that may be otherwise unavailable in your country. Websites can sometimes become blocked by a country due to geo-blocking or localized censorship, but a VPN service helps to override this issue. A popular use of a VPN service is to access streaming websites from other countries, for example, Netflix, helping users to expand their library of potential shows to watch.

Will a VPN protect you on a public WiFi?

The short answer to this is yes, a VPN service will definitely help to protect you on public WiFi. By using an encryption tunnel to connect users in the first place, this means that all your data is encrypted for the total security of all personal details. Without an IP address, your browsing history, location, and other personal information is also masked, so you are unidentifiable for the duration of using the public WiFi connection.

A VPN service can be a great tool for a number of different users, who may have a variety of reasons for wanting to keep their information private and protected. This can include anything from students working on important assignments to those traveling around the world and aware of the potential security pitfalls of public WiFi. It is also a great way for anyone to save mobile data without the worry of compromising their online privacy
