We have been working with a customer to deploy Microsoft Windows Intune at a number of their sites across the UK.
The sites are all setup with different and non-centralised security models (workgroup and Windows domain) over ADSL connections, and managing machines has historically been very difficult and time consuming.
Deploying Intune is enabling the client to support multiple devices across their estate, keeping software up to date, setting security policies and remotely monitoring status from a central administration point. Intune also brings with it the capability to manage their Android and Apple iOS clients as well as traditional Windows PC's.
It's yet another cloud service that has delivered real benefit in a real world deployment.
