What is a VPN and do you need one?
A VPN, or virtual private network, creates a protected tunnel for your internet traffic. You will see them advertised everywhere, so it is worth knowing what they do and do not do.
What a VPN does
When you use a VPN, your traffic travels through the VPN company's servers before reaching the website. This has two main effects:
- People on the same network, such as in a cafe or hotel, cannot easily read what you send.
- Websites see the VPN company's address instead of your own, which hides your rough location.
What it does not do
- It does not stop viruses or scams.
- It does not make you anonymous. The VPN company can still see some information.
- It does not make you safe if you type your password into a fake website.
- It usually will not make your internet faster. It can slow it down.
When a VPN is useful
- Using public Wi-Fi in cafes, airports or hotels.
- Connecting to your workplace securely, if your employer provides one.
- Wanting extra privacy from your internet provider.
When you probably do not need one
At home, on a secured network, with updated devices and strong passwords, a VPN adds little for everyday use. Most websites already protect your connection, which you can see from the padlock in the browser.
Choosing carefully
- Avoid free VPNs, as they may collect and sell your data.
- Choose a well-known paid service with a clear privacy policy and good reviews from independent sources.
- Download apps only from official app stores or the company's own website.
- Be wary of adverts or pop-ups that claim your device is at risk and push a VPN.
Problems a VPN can cause
Some banks, streaming services and websites block VPN traffic. If a site will not work, turn the VPN off and try again.
