Case Studies

Providing Trusted Services to Government

As a result of the hijacking of four aircraft in the USA on 11 September 2001, then Australian Prime Minister announced in October 2001 that Australia would have armed air marshals flying on Australian carriers in an anti-hijacking role and that they would be operational by 31 December 2001. At this time, Australia had no such capability and, therefore, there was no directly-relevant expertise in Australia to meet this directive.


Members of Citadel’s advisory team were contracted to establish the capability for Government. This included strategic issues (such as the high-level planning considerations, legislation, inter-agency cooperation, and funding) and operational delivery of the program (initial recruitment, training, tactics, methods of operation, and liaison with the airlines). We had less than six weeks to have the capability deployed.

Because we were establishing a completely green fields program, our team faced the following issues:

  • no trainers with expertise in Air Security Officers (ASO – air marshals) operations
  • no trainees or mock-up aircraft to train in
  • no agreement with the airlines, pilots or cabin crew
  • no legal agreement on powers
  • no conditions of service for ASO
  • no equipment, weapons, handcuffs or rig to carry equipment under clothing
  • no agreement by Government Departments with regards to the myriad of approvals needed to have armed officers on aircraft flights
  • no agreement on what ports ASO were to fly in and out of
  • no agreement with airport corporations to allow ASO to bypass screening (scanners would have detected the firearms and compromised identities of ASO to security point staff); and
  • no agreed funding


Each of the above challenges needed to be resolved and the first officers deployed on selected domestic flights within six weeks, so we established multiple concurrent work teams and empowered them to develop innovative solutions for subsequent consideration and approval. Once approved by Government, we then presented the concepts to Qantas, Ansett and Virgin Blue management, and ‘tweaked’ where necessary to ensure all stakeholders were clear of the requirement and committed to the program’s success.


Following a very busy six weeks, on 24 December 2001, we received the final Government authorisation to proceed and ASOs flew for the first time on board Australian aircraft at 4.30pm.


In 2004, Qantas senior managers went before a Parliamentary Committee and stated on the record that “the Australian ASO program is without doubt the world’s best practice”.

Cyber Security

A large national telecommunications infrastructure client was seeking to ensure that its networks and infrastructure were appropriately protected from hostile cyber threats. While the number and severity of these threats changed regularly, the below summary of one day’s activities highlights the extent of the cyber threats needing to be resolved in order to maintain operations:

  • 290,003 email spam
  • 160,112 botnet and phishing attacks
  • 454 spyware and malware
  • 45 viruses
  • 15 direct denial of service attacks
  • 96 unknown encrypted existing information files
  • 142 other unidentified and unresolved threat events


We conducted a risk review of the client’s networks, applications and infrastructure, and provided a complete blueprint for establishing a layered cyber protection regime inclusive of training, specialist hardware and software, test labs, and a 24/7 cybersecurity operations centre for identifying, containing, resolving and recovering from cyber threats.


The implemented solution saved the organisation over $3.4 million per annum in improved network and application up-times, and through measurably enhanced levels of customer satisfaction.


Citadel provided these advisory and implementation services in 2013, and the client’s most sensitive systems still remain fully protected and free from an increasingly hostile cyber threat vector.
