A successful business is a secure business. You probably have a good lock on the front door, maybe an alarm system, and secure cabinets for important documents. You do all of this to protect your business' physical assets from threats. So why wouldn't you do the same for your digital assets?
Just as you have physical security measures, your business also needs strong cybersecurity policies. They help create clear rules for employees to follow and a plan to fall back on if an incident occurs.
