OneGUARD® is a fully Australian-owned and independently operated cybersecurity consultancy headquartered in Canberra. Since 2008, we have helped Australian Government agencies, Defence and Defence industry, critical infrastructure operators and major enterprises secure systems and build their people’s capability.
Our leadership includes one of Australia’s longest continuously endorsed IRAP Assessors and a leading trainer of IRAP assessors—with more than 500 students trained and 200 endorsed. Our roots include founding involvement in the NSWC Shadow IDS project and leadership of SANS GIAC’s Asia-Pacific incident-response operations from December 1999.
