The Australian Defence Force

The Australian Defence Force (ADF) is constituted under the Defence Act 1903, its mission is to defend Australia and its national interests. In fulfilling this mission, Defence serves the Government of the day and is accountable to the Commonwealth Parliament which represents the Australian people to efficiently and effectively carry out the Government’s defence policy.

The primary role of Defence is to defend Australia against armed attack. Australia’s defence policy is founded on the principle of self-reliance in the direct defence of Australia, but with a capacity to do more where there are shared interests with partners and allies.

CitadelTech has been supporting the Defence Secure Video Environment (DVSE) since its inception in May 1997. We provide managed services to more than 300 sites nationally and manage an average 1000 DVSE conferences per month.

The Business Need

In 1997 the Department required a trusted and experienced Video Communications and Collaboration partner who could consult, design, install, manage and support all VC&C equipment in a secure environment.

Since 1997, The Department of Defence have required a range of industry led but security focused solutions. This included designs and flexible support services to ensure operational costs were predictable and controlled.

This included the ability to provide a dedicated Videoconferencing Network Operations Centre (VNOC) that would support the Department during business hours for domestic business use and 24 x 7 services to all Government deployed capabilities.

The deployed systems include mission critical systems that support the Australian Government activities within the Middle Eastern Area of Operations (MEAO).

The VNOC support capability maintains standard hours to provide a cost effective ad-hoc and scheduled 24×7 support service to over 1000 sites nationally and internationally.

The VNOC needed to be able to support both ISDN and IP video networks as well as cater for fixed and deployable technologies

CitadelTech is responsible for the design, installation and end-to-end managed service of over 30 endpoints per conference across 400 endpoints throughout Australia and overseas.
