The National Cyber Security Centre has a five step plan to help businesses secure themselves and so reduce the risk of becoming a victim of a cyber attack.
Following their five quick and easy steps outlined in the guide could save time, money and even your

business’ reputation. The guide can’t guarantee protection from all types of cyber attack, but the steps outlined can significantly reduce the chances of your business becoming a victim of cyber crime.
See the guide here and help protect yourself and your business.

If you want to improve your cyber security further, then you can also seek certification under the Cyber Essentials scheme, which has the benefit of demonstrating to your clients (or prospective clients) that you take the protection of their data seriously.
