Global Defense Cybersecurity Market Size, Share, Trends, and Industry Forecast, 2026-2036 | Market to Reach USD 58.03 Billion as Zero Trust, AI, and Post-Quantum Security Drive 8.9% CAGR

Dublin, Oct. 28, 2026 (GLOBE NEWSWIRE) -- "Defense Cybersecurity Market Size, Share, and Industry Analysis - Global Forecast to 2036" has been added to ResearchAndMarkets.com's offering.

The global defense cybersecurity market was valued at USD 22.80 billion in 2025 and is estimated to reach USD 24.74 billion in 2026. It is projected to expand to USD 58.03 billion by 2036, registering a CAGR of 8.9% during the 2026-2036 forecast period. The report evaluates market size, defense cyber budgets, threat and technology landscapes, regulations, pricing, procurement criteria, M&A activity, the competitive environment, and the industry value chain.

Demand encompasses cybersecurity solutions and services purchased by militaries, defense ministries, government agencies, cyber commands, and defense contractors. Investment is focused on protecting military networks, command-and-control systems, weapon platforms, tactical communications, space assets, classified environments, and defense supply chains. Offensive cyber capabilities and uniformed personnel costs are excluded from the market assessment.

Defense cybersecurity market dynamics

Persistent attacks by state-sponsored groups remain a primary market driver. In June 2025, the Department of Homeland Security reported that Salt Typhoon had penetrated a U.S. Army National Guard network between March and December 2024, obtaining administrator credentials, network diagrams, and service member data. Incidents of this scale are increasing spending on round-the-clock monitoring, threat hunting, incident response, network protection, and secure infrastructure.

The U.S. remains the largest defense cybersecurity buyer. The Pentagon requested approximately USD 15.1 billion for cyberspace activities in fiscal year 2026, including USD 9.1 billion for cybersecurity and USD 5.4 billion for cyberspace operations. In Europe, the U.K. established a Cyber and Electromagnetic Command and committed more than GBP 1 billion to a Digital Targeting Web scheduled for delivery by 2027.

Zero trust adoption, weapon system digitization, cloud migration, and supplier security mandates are accelerating market growth. The CMMC rule entered U.S. defense contracts on 10 November 2025 and will be implemented through November 2028. Comparable initiatives, including the U.K. Defence Cyber Protection Partnership, are extending cybersecurity requirements across contractor ecosystems.

Market expansion is constrained by legacy infrastructure, classified and air-gapped networks, extended accreditation cycles, procurement delays, and shortages of cybersecurity professionals with security clearances. Supply chain integrity and interoperability among allied systems and classification levels also remain significant challenges.

Major opportunities include post-quantum cryptography, AI-enabled security analytics, tactical edge protection, uncrewed system security, and safeguards for proliferated satellite constellations. Post-quantum migration is expected to create a long-term investment cycle across networks, radios, satellites, weapon systems, and key management infrastructure. AI-enabled tools that correlate telemetry, prioritize alerts, and automate response are also becoming increasingly important as defense organizations address workforce constraints.

Segment outlook

Services are expected to hold the larger market share in 2026 because systems integrators and defense contractors manage substantial portions of military network infrastructure. Demand is rising for managed security, assessment, compliance, training, and integration services. Cybersecurity solutions are forecast to record the higher CAGR as defense organizations deploy new platforms for zero trust, cryptographic modernization, cloud security, data protection, and advanced analytics.

Network security is expected to lead by solution type in 2026, supported by extensive defense network infrastructure and sustained attacks on routers, gateways, and other network devices. Identity, access & zero trust is projected to grow at the highest CAGR as agencies increase spending on identity management, segmentation, and continuous verification. Cryptographic modernization will also gain momentum as quantum-resistant technologies move into military communications and connected platforms.

Enterprise IT networks are expected to represent the largest security domain, while weapon systems & platforms are projected to grow fastest. Modern aircraft, ships, vehicles, sensors, and command systems increasingly depend on software and connected data links, creating additional cybersecurity requirements.

On-premises deployment is forecast to retain the largest share in 2026 because classified networks and legacy systems often cannot use public cloud services. Cloud deployment is expected to achieve the highest CAGR as sensitive workloads move to accredited commercial and classified environments.

Defense agencies & cyber commands are expected to lead by end user, supported by their responsibility for enterprise networks and cyberspace operations. The defense industrial base is projected to grow fastest as CMMC and allied supplier requirements drive assessments, remediation programs, and continuous monitoring among contractors.

Regional market outlook

North America is expected to remain the leading regional defense cybersecurity market in 2026. The region benefits from significant U.S. Department of Defense spending, extensive CMMC implementation, and a strong base of systems integrators, prime contractors, cloud providers, and commercial cybersecurity vendors.

Europe is projected to register the highest CAGR through 2036. Growth will be supported by expanding defense budgets, NATO security commitments, new British cyber programs, and heightened exposure to Russian cyber and hybrid threats. The U.K., Germany, France, Poland, and the Nordic and Baltic states are expected to make substantial contributions.

Asia-Pacific will maintain a significant market share, driven by military cyber investment in Japan, South Korea, Australia, India, Taiwan, and China. Israel, Saudi Arabia, and the UAE will support demand in the Middle East & Africa, while Brazil is expected to lead Latin America.

Competitive landscape

The defense cybersecurity market is moderately fragmented, with government systems integrators, defense prime contractors, cloud providers, commercial security platforms, and specialist firms competing for contracts. Procurement decisions emphasize cleared personnel, accreditations, mission expertise, contract access, workforce capacity, and capabilities in zero trust, cloud security, cross-domain systems, and cryptographic modernization.

Companies profiled include Booz Allen Hamilton Holding Corporation, Leidos Holdings, Inc., CACI International Inc, Science Applications International Corporation, General Dynamics Corporation, Lockheed Martin Corporation, Northrop Grumman Corporation, RTX Corporation, Parsons Corporation, BAE Systems plc, Thales S.A., Leonardo S.p.A., Airbus SE, Elbit Systems Ltd., Palo Alto Networks, Inc., CrowdStrike Holdings, Inc., Cisco Systems, Inc., Microsoft Corporation, Fortinet, Inc., and Everfox.
