Introducing Cisco Cloud Mailbox Defense


The number of UK companies utilising Microsoft Office 365 as of February 2020. The requirement for remote working is only going to see this number increase with Gartner expecting 70% of public ad private organisations to be using cloud email services by 2021.

The numbers are not surprising. Microsoft 365 is the go-to for remote working capabilities with the applications and services able to run on any device.
