Your device and your personal data

With smartphones, tablets and other devices containing a wealth of personal information they have become more attractive to criminals not just for the cost of the phone but for access to the data inside it too. Manufacturers have put in controls that will help you keep your device and data secure. Take some time to go through and set up the security options when you buy a new device and review the settings again every few months.

You can go directly to the manufacturers websites for their guides by following the links below (will take you to external websites). We’ve also included a rundown of our top tips to secure your device after the links.
