If you have employees carting around laptops packed with data sensitive to your business, you should be taking added security measures. It’s all too easy to nab a laptop from a vacant chair while the user isn’t looking. No matter how strong the password, it will almost certainly be cracked, leaving anything unencrypted on the laptop ripe for the taking.
To avoid this, it’s a good idea to keep all your sensitive data in one secure cloud service, meaning it’s never actually on your employee’s hard drive at all. When an item goes missing, you can easily revoke access from that machine.
