Seabed Security Market Report 2026

The seabed security market size has grown strongly in recent years. It will grow from $6.33 billion in 2025 to $6.81 billion in 2026 at a compound annual growth rate (CAGR) of 7.5%. The growth in the historic period can be attributed to increasing offshore oil and gas exploration, rising submarine cable installations, adoption of ROVs and AUVs for inspection, growth in offshore renewable energy projects, rising government and defense monitoring initiatives.

The seabed security market size is expected to see strong growth in the next few years. It will grow to $9.18 billion by 2030 at a compound annual growth rate (CAGR) of 7.7%. The growth in the forecast period can be attributed to growing demand for deep and ultra-deepwater infrastructure security, increasing use of AI-enabled threat detection software, expansion of remote monitoring and analytics capabilities, rising integration of IoT-enabled underwater sensors, increasing investments in subsea security services. Major trends in the forecast period include increasing adoption of real-time subsea monitoring systems, rising deployment of autonomous underwater vehicles for security, growing integration of threat detection software with infrastructure, expansion of maintenance and consulting services for subsea assets, rising focus on protection of critical submarine communication cables.

The increasing demand for maritime security is anticipated to propel the growth of the seabed security market in the coming years. Maritime security encompasses the protection of a nation’s maritime domain, including its waters, ports, vessels, offshore assets, and digital systems, against threats such as piracy, terrorism, smuggling, illegal activities, and cyberattacks, thereby ensuring safe and secure navigation and trade. This rising demand is largely fueled by escalating geopolitical tensions, as disputes over maritime boundaries, strategic waterways, and offshore resources elevate the risk of conflicts, piracy, and cyber threats, necessitating enhanced surveillance and protection measures. Seabed security contributes to maritime security by facilitating monitoring and safeguarding of critical underwater infrastructure, enabling early detection of underwater threats or unauthorized activities, thereby strengthening surveillance, securing communication networks, and enhancing overall maritime safety and defense. For instance, in October 2023, according to the Offshore Energy Exhibition & Conference (OEEC), a Netherlands-based event management company, the average cost of a cyberattack in the maritime industry increased from $182,000 in 2022 to $550,000 in 2023. Therefore, the increasing demand for maritime security is driving the growth of the seabed security market.

Leading companies operating in the seabed security market are focusing on advancements in underwater surveillance systems, such as underwater early warning sensor networks to detect intrusions or anomalies and provide real-time alerts to potential threats. An underwater early warning sensor network refers to a system of subsea sensors and detection devices deployed across strategic underwater areas to monitor and protect critical infrastructure on the seabed, with networked communication linking the sensors to a central command center for real-time data analysis and alerting. For example, in October 2025, Fincantieri S.p.A., an Italy-based shipbuilding and defense company, launched the DEEP underwater drone system, a sophisticated seabed security solution designed to enhance the protection of critical underwater infrastructure. The system integrates an early-warning sensor network for continuous subsea monitoring, autonomous underwater vehicles (AUVs) for rapid anomaly detection and inspection, and a centralized command-and-control platform leveraging real-time data integration and AI-driven analytics to identify and prioritize potential threats. It provides scalable, persistent security for assets such as pipelines and submarine cables while offering flexible, modular deployment for both shore-based and fixed installations. Additionally, the system supports dual-use applications across civil and defense sectors and can be seamlessly integrated with existing maritime surveillance networks to improve situational awareness and enable faster response across extensive seabed areas.

In March 2024, Fincantieri S.p.A., an Italy-based shipbuilding and defense company specializing in naval vessels and underwater defense systems, entered a collaboration agreement with Saipem S.p.A. to combine naval defense expertise with advanced subsea robotics and engineering capabilities. Through this collaboration, Fincantieri aims to strengthen its capabilities in seabed warfare and the subsea domain by combining its naval defense expertise with Saipem’s advanced offshore robotics and subsea engineering technologies, thereby propelling innovation and contributing to the development of autonomous underwater systems and solutions for monitoring and protecting critical underwater infrastructure. Saipem S.p.A. is an Italy-based engineering and construction company specializing in offshore energy services, subsea robotics, and underwater infrastructure technologies, supporting advancements in underwater operations.
