Cybersecurity woes

Digital prints always fascinated me from when I saw a movie poster. Maybe this was what prompted me to start my own business in the same field. The business is running fine now. We've got enough clients for the business to be successful. The reason why I am writing here is because of what happened to my friend. He owns a printing business too. Last week all of the pcs at his office was hacked and every single piece of data he had was deleted. This included all the files needed for printing this affected the business really bad. He is still trying to recover from this. This incident actually scared me a bit. I hired a cyber security consulting firm to analyze my security. Now I am questioning my own decision, am I spending money on something that we can ourselves?
