Birrana Engineering, leader in the design, manufacture and servicing of mining transport equipment has made dramatic changes to the efficiency of its Virtual Private Network since installing a NetBox in each of its locations. The company had been relying on an antiquated and unsupported VPN solution, but the suite of features offered in the NetBox has given the company unprecedented control over its network. The combination of traffic shaping (Quality of Service), web filtering, pre-delivery spam filtering and improved bandwidth, all provided on an IBM hardware platform, help to ensure Birrana retains its position as an indispensable partner to the Australian mining industry.
