The Australian Cyber Security Centre (ACSC) leads the Australian Government’s efforts to improve cyber security. Our role is to help make Australia the safest place to connect online.
We monitor cyber threats across the globe 24 hours a day, seven days a week so we can alert Australians early on what to do.
We provide advice and information about how to protect yourself and your business online. When there is a cyber security incident, we provide clear and timely advice to individuals, small to medium business, big business and critical infrastructure operators.
We work with our business, government and academic partners and experts in Australia and overseas to investigate and develop solutions to cyber security threats.
We have a national footprint of Joint Cyber Security Centres where we collaborate with nearly 200 industry, government and academic partners on current cyber security issues. We also work with law enforcement authorities to fight cybercrime.
We are part of the Australian Signals Directorate (ASD), which has a long history of cyber security excellence. For more information about the ACSC, visit our corporate page.
Cyber security is everyone’s responsibility. Let’s work together to make Australia the safest place to connect online.
