Top gadgets and apps to protect your mobile devices

It is far too easy to lose USB sticks containing our important documents, slices of our lives, photos, videos and potentially sensitive information.

However, if you are unfortunate enough to lose one, it isn't quite as critical if it is properly protected.

Many companies now offer USB flash storage drives with security options, such as datShur. This 3.0 USB key, available in a range of storage options, is PIN activated and protected with built-in XTS-AES 256-bit hardware encryption.

Sometimes, the best security solutions for preventing spontaneous theft are the most simple. Consider investing in a locking device for your laptop while you're out and about which prevents your device from being easily stolen from a library desk or your room while you are elsewhere.

If you buy such a lock, while they will fit most models, make sure your laptop is compatible.
