Aerospace & Defense Cybersecurity Market: Growth, Trends & Forecast (2025-2030)
The global aerospace and defense cybersecurity market is projected to reach $25.3 billion by 2030, growing at a compound annual growth rate of 8.3% from 2025, according to a new report. This growth is driven by increasing cyber warfare activities, the digitalization of mission-critical systems, and stringent defense compliance regulations.
The market is currently valued at $15.7 billion as of 2024. Solutions are expected to dominate the market throughout the forecast period, with the data, signal & cryptographic security segment leading growth at a rate of 11.1%. Cloud-based deployments held an estimated 29.2% market share in 2025.
Key players in the aerospace and defense cybersecurity market include Thales Group, Lockheed Martin, BAE Systems, Leonardo, Airbus, Northrop Grumman, Honeywell, Rheinmetall, GDIT, IBM, DXC Technology, Booz Allen, Hanwha Systems, Noventiq, and CS Engineering. These companies offer capabilities in secure communications, mission systems integration, zero trust architecture, encryption, and defense cloud solutions, often supported by strong government partnerships. Agile startups like Decent Cybersecurity, CAVIAR DATA, TYREX, Atomus, and Globals are likewise contributing with advanced threat detection and encryption technologies.
The increasing digitization of aerospace and defense systems – including satellite networks and autonomous platforms – is expanding the attack surface and driving investment in advanced security measures. Nation-state actors are increasingly targeting these systems for espionage and disruption, prompting organizations to prioritize proactive cyber defense strategies. The need to protect sensitive military information and critical infrastructure is paramount.
Recent developments highlight the growing collaboration within the industry. In February 2026, BAE Systems partnered with Sigma Software Group to bolster cyber resiliency for Ukraine and NATO allies. Also in February, Leonardo and Indra Group signed a memorandum of understanding to jointly develop advanced cyber defense solutions for European institutions and critical infrastructure. In December 2025, Thales and SeedFence were selected by the French national space agency CNES to provide onboard cyber detection for space platforms.
The market is segmented by offering, solution type, deployment mode, organization size, and end user. Tier 2 & 3 sub-system suppliers are projected to experience the highest growth rate among organization sizes. Space systems are anticipated to grow at the fastest rate among end users, at 11.0% from 2025 to 2030. The military & defense segment currently accounts for a significant share of the market, fueled by investments in secure air, naval, land, and space infrastructure.
Complex supply chains, involving numerous contractors and subcontractors, present a significant challenge. Ensuring consistent security standards and real-time threat monitoring across the entire ecosystem remains a critical focus. Strict compliance mandates and lengthy procurement processes can also gradual the adoption of advanced cybersecurity technologies.
The Asia Pacific region, particularly India, is expected to be the fastest-growing market for aerospace and defense cybersecurity due to defense modernization efforts and increasing digitalization. This growth is driving demand for zero trust architectures, AI-based threat detection, and secure defense cloud services.
