Encryption is a powerful weapon against hackers that can prevent them from stealing your data and leveraging it against you. Encryption, in its most basic textbook definition, converts your readable data into an indecipherable jumble that can only be reassembled through the use of an encryption key. Small businesses absolutely must utilize encryption to protect customer information, financial records, and other important or sensitive business data. This ensures that it is as protected as possible against those that might do you harm.
