What security solutions for the company?

I am looking for solutions that will help me manage data security in my company. What methods do you use?

I have been running my own business for many years and I am aware of the importance of cooperation with specialists. So for my business, I started working with Secfense - https://secfense.com/blog/what-is-u2f-key/ , which specializes in implementing modern authentications instead of traditional old passwords. Have any of you used their services?
