Australian Signals Directorate

ASD’s purpose is to defend Australia from global threats and help advance Australia’s national interests. We do this by mastering technology to inform, protect and disrupt.

• Informing – by the covert acquisition of foreign information not publicly available (signals intelligence)
• Protecting – by comprehensively understanding the cyber threat, providing proactive advice and assistance to improve the management of cyber risk by government, business and the community
• Disrupting – by applying our offensive cyber capabilities offshore, to support military operations, counter-terrorism, counter cyber espionage and serious cyber-enabled crime.

ASD operates in the slim area between the difficult and the impossible.
