Defense cyber security market seen growing 11.7% annually to 2030

The Business Research Company says the defense cyber security market is set to rise from $27.33 billion in 2025 to $47.44 billion by 2030, driven by higher defense spending, geopolitical tensions and the shift to cloud-native military systems. North America led the market in 2025, while Asia-Pacific is expected to grow fastest.

Why it matters: - Defense cyber security is becoming a core defense priority as military networks, platforms and sensitive data face more frequent digital attacks. - The market’s growth signals continued spending on tools that protect battlefield communications, critical infrastructure and classified information. - The forecast points to broader demand for real-time defense against both nation-state and non-state hackers.

What happened: - The Business Research Company released its Defense Cyber Security Market Report 2026 – Market Size, Trends, And Global Forecast 2026-2035 on July 17, 2026. - The report says the market will grow from $27.33 billion in 2025 to $30.47 billion in 2026. - The report projects the market will reach $47.44 billion by 2030, implying an 11.7% CAGR. - The company also published a free sample of the report and a full report page.

The details: - The 2025 to 2026 increase reflects an 11.5% CAGR. - The report ties near-term growth to state-sponsored cyber warfare, more digitized defense communications, legacy network infrastructure, perimeter-based security frameworks and early encryption use in military communications. - The report says future growth will be supported by autonomous warfighting systems, better connectivity for unmanned platforms, AI-powered threat intelligence, cloud-native defense infrastructure and stronger real-time protection for battlefield data. - Expected trends include cloud-native security orchestration, automated threat response, zero trust models across military networks, advanced endpoint detection with predictive analytics, encrypted tactical communications and broader use of managed detection and response services. - The report defines defense cyber security as protection for military networks, platforms and sensitive government data from unauthorized digital intrusions and cyberattacks. - The report says the field is meant to preserve the security, integrity and availability of defense systems and communication lines. - It identifies North America as the largest regional market in 2025. - It identifies Asia-Pacific as the fastest-growing region in the years ahead. - The report covers Asia-Pacific, South East Asia, Western Europe, Eastern Europe, North America, South America, the Middle East and Africa. - The 2026 edition adds market attractiveness scoring, TAM analysis, company scoring matrix graphics and tables, Excel-based forecasting dashboards, market hotspots infographics, key technologies and future trend analysis, and updated graphics and tables.

Between the lines: - Defense cyber security is being pulled by two forces at once: rising attack risk and higher defense budgets. - The report cites geopolitical tensions as a reason governments are spending more on cyber defense, not just traditional weapons systems. - SIPRI reported in April 2026 that global military expenditure rose 2.9% in real terms to $2,887 billion in 2025, reinforcing the broader spending backdrop. - The emphasis on automation, zero trust and cloud-native systems suggests defense buyers are moving away from perimeter-only security models.

What's next: - The market outlook points to continued procurement of AI-based threat tools, encrypted communications systems and managed security services. - Defense organizations are likely to keep modernizing networks as autonomous systems and unmanned platforms become more connected. - Regional leadership may remain split, with North America anchored by established budgets and Asia-Pacific gaining share through modernization and geopolitical pressure.

The bottom line: - Defense cyber security is moving from a niche IT function to a strategic military priority, and the market data points to sustained double-digit growth through 2030.
