At DCSI, we strive to make communications simple for our customers, allowing you to run your business better.

DCSI Business

DCSI Business services are delivered on one of Australia’s largest and highest capacity networks. In addition to our own infrastructure in Gippsland and Melbourne’s South East, we are able to seamlessly integrate 3rd party services into solutions for our customers.
Go to Business Class Internet

Business Class Internet

For business, ADSL or NBN often can’t provide the performance and reliability that your business needs. That’s why at DCSI we have a range of business class internet services that outperform residential services.



For businesses operating multiple offices, or those demanding greater security and functionality, an MPLS WAN is the only solution. Faster and more reliable than IPSEC or other ‘software’ VPN options, MPLS WAN solutions will always be the best choice for those demanding performance and reliability.
