Laptops are more and more prevalent in the workplace today. You can take them on business trips, plug them into a 'real' monitor and keyboard when you are at work and they are easy to pack up and move down the hall if needed.
This portability also means they are more likely to be stolen.
Storing your critical business information on a laptop means that if it is stolen, someone else now has access to everything. This could well include your accounting software, spreadsheets with detailed financial information and copies of invoices among other things that you might not want published to the world.
You may have passwords on your laptop, but with physical access to the machine, they offer little protection.
One option to prevent the loss or theft of financial or personal information is to ensure that it is not actually stored on the laptop. Using web based services such as Troove to store and manage your data provides an extra layer of physical security that does not exist with a personal computer.
