Apple talks a lot about privacy, but with Pegasus hitting the headlines, people are beginning to realise that the promises aren't as iron-clad as they thought.
A VPN won't help prevent such malware from attacking your iPhone, but what it will do is protect your privacy when you're online. For example your movements can be tracked by the websites you visit in Safari (or another browser) and your internet service provider can also see what you're up to, whether you're connected to Wi-Fi or using 3G, 4G or 5G.
Using a VPN can keep all this information private, preventing companies knowing what you buy, where you shop, what you watch, when you go to bed and where you're going on holiday.
A VPN also hides your location, which has a secondary benefit of allowing you to access content and blocked sites such as US Netflix when you are in the UK or BBC iPlayer when you are abroad.
It's important to note that using a VPN to get around geo-restrictions is usually against the terms and conditions of Netflix, BBC & Amazon.
While a VPN is new for many people, they are very simple apps to use and require no previous knowledge or technical expertise. It's as easy as launching the app, pressing the 'connect' button and then launching Safari or whichever other app you want to use.
