“Previously working with CyberOne as a Global CIO for a FTSE 100 organisation, we needed to mature our cyber security strategy and how we implemented it. From that great experience with them it brought me back to using them again using Microsoft Security and their Assure 365 Managed Microsoft Security solution.
So from prior hands-on experience, it was nice to see and work with some of the same faces I had previously worked with so successfully. CyberOne are very good at delivering results fast. What I do see now is a real visibility across the stack, I see the regular reporting and I feel a lot more confident that our security is in a much better place with CyberOne.”
