Why You Should Encrypt Your Hard Drive

If employees are using laptops and taking them out of the office, there's a risk of the laptop being accessed by an outsider of the business or stolen. Without encryption anyone can find, open, edit and download any files. Encryption on the hard drive will make it impossible for anyone to access files without the password or security key. It simply adds an extra layer of protection on devices storing sensitive information.

Allowing all employees of a business to view all files is a  security risk. Limiting access to employees who can view the files will mitigate the risk of any data being leaked causing a data breach.

Disk disposal, having data encrypted will ensure a safe and secure disposal of a disk/device whether it be selling the device on or complete disposal. No data will be leaked or accessible to anyone else without the encryption key.
