Defense cybersecurity market seen reaching $62.3 billion by 2030

The global defense cybersecurity market is projected to grow from $39.73 billion in 2026 to $62.3 billion by 2030, driven by rising cyber warfare, military digitization and demand for AI, cloud and post-quantum defenses. North America leads the market now, while Asia-Pacific is expected to grow fastest.

Why it matters: - Defense networks, weapons platforms, communication systems and intelligence assets are facing more frequent and more complex cyberattacks. - The market is expanding as governments and defense contractors spend more to protect military operations, critical infrastructure and national security systems. - Growth in this sector reflects a broader shift toward digitally connected defense operations, which also expands the attack surface.

What happened: - The Business Research Company released its Defense Cybersecurity Global Market Report 2026 on Sept. 8, 2026. - The report estimates the defense cybersecurity market will increase from $35.58 billion in 2025 to $39.73 billion in 2026. - The report forecasts the market will reach $62.3 billion by 2030. - The company projects a 11.7% CAGR from 2025 to 2026 and a 11.9% CAGR through 2030. - North America was the largest regional market in 2025. - Asia-Pacific is expected to be the fastest-growing region over the forecast period.

The details: - Defense cybersecurity covers the protection of military and national security technology from espionage, malware, ransomware and cyber warfare tactics. - The market’s recent growth has been driven by rising cyber warfare incidents, digitization of defense capabilities, investment in military network security and critical infrastructure protection programs. - The report links future growth to wider adoption of AI-powered cyber defense tools, cloud-based security platforms and quantum-resistant encryption. - The report also points to stronger security needs for autonomous military systems and increased government funding for cyber resilience. - Emerging trends include zero trust security frameworks, post-quantum cryptography, security orchestration automation and response platforms, multi-domain cyber defense strategies and stronger threat intelligence programs. - The report cites National Cyber Security Centre data showing 204 nationally significant cyberattacks in the UK in the year ending September 2025, up from 89 in the prior year. - The broader regional coverage includes Asia-Pacific, South East Asia, Western Europe, Eastern Europe, North America, South America, the Middle East and Africa. - The company is offering a free sample of the report at the sample request page. - The full report is available at the market report page.

Between the lines: - The forecast shows defense cybersecurity moving from a support function to a core part of military modernization. - Faster growth in Asia-Pacific suggests defense buyers there are accelerating spending on digital protection as modernization programs expand. - The jump in UK cyber incidents underscores why security spending is likely to stay elevated across defense and national security systems.

What's next: - The report expects demand to keep rising as defense agencies adopt AI, cloud security and post-quantum protection. - Zero trust, SOAR platforms and multi-domain defense strategies are positioned to shape the next wave of procurement and product development. - Continued government funding for cyber resilience should support market expansion through the rest of the decade.

The bottom line: - Defense cybersecurity is moving into a higher-growth phase as militaries try to keep pace with more advanced and more frequent cyber threats.
