We have just completed a new cloud managed infrastructure project for an oil and gas exploration company in London. This includes fully managed firewall, LAN switching and wireless access points. They have a high speed guest wireless environment that is integrated, yet totally separate and secured from their office network.
We also deployed a cloud managed printer that allows people to print to it via its email address and a IP based CCTV system.
The additional benefit is that the company now have a fully managed network with full monitoring and reporting and they will never need to employ a telecomms or network infrastructure person. This gives them immediate cost savings from day 1.
