Top Cybersecurity Companies in Australia
Updated 13 Dec 2025
Australia’s digital economy continues to expand rapidly across banking, healthcare, mining, ecommerce, logistics, and public services. With this growth comes increased exposure to cyber risk. According to recent industry reports, the Australian cybersecurity market is now valued at over USD 9–10 billion and is projected to surpass USD 18 billion by 2030, growing at a double-digit CAGR.
