Challenges facing businesses today


Cyber attacks are targeted at all businesses, large and small, and their impact can be devastating. Over 65,000 cyber attacks are attempted each day on UK small businesses, and around 4,500 a day are successful1. For larger organisations, the average cost of a security breach is estimated between £600K to £1.15 million2

From securing an employee’s mobile device to securing complex networks. Every organisation has a different requirement but one common goal – to protect their people, data and business. And this means making sure they aren’t the victim of a cyber attack. 

Ensure you have the right cyber protection with O2 Business.
