Maritime Cyber Security Services
Legacy OT
Vessel Systems
Attacks on maritime OT increased by 150% in 2025, with 87% driven by ransomware. 71% of maritime professionals believe that their OT assets are more vulnerable to cyberattacks than in the past. In 2023, only 40% of surveyed maritime professionals believed their organization was investing enough in cybersecurity.
Unsecured Fleet
Network Access
50% of all maritime OT cyberattacks originate through unauthorized access. Attacks targeting routers, VPNs, and firewalls, increased by 800%, reflecting a widening threat landscape. Furthermore, 31% of maritime professionals experienced at least one cyber attack in the last year.
Port Terminal
System Exposure
Only 53% of critical-infrastructure professionals reported confidence in full visibility of supply-chain cybersecurity vulnerabilities, exposing port terminal systems and increasing cyberattack risk. The Port of Los Angeles suffered cyberattacks ranging from 7 million attempts/month in 2014 to 60 million attempts/month in 2023, while cyber incidents increased globally by 103% from 2024 to 2025.
IMO and USCG
Compliance Gaps
Operating with compliance gaps can trigger immediate enforcement during port audits, with inflation-adjusted civil penalties under 33 CFR § 27.3 (46 U.S.C. § 70119) reaching $43,527 per violation and up to $78,210 per day for continuing MTSA non-compliance, alongside costly vessel detention orders and commercial off-hire losses.
Crew Cyber
Awareness Gaps
Untrained personnel invite cyberattacks through simple mistakes. 97% of maritime cyberattacks consist of trying to trick an employee by using social engineering techniques. Separately, 24% of cyberattack victims surveyed in 2023 were tricked into transferring funds to criminal organizations.
Ransomware
Disrupting
Operations
Ransomware attacks lock ship data storage, electronic maps, and freeze communication. Maritime ransomware cases jumped from 156 in 2024 to 372 in 2025. However, the average maritime cyberattack costs $550,000, while the average ransomware payment is $3.2 million. .

Frequently Asked Questions (FAQs)
What is maritime cyber security and why does it matter for shipping companies?
Maritime cyber security protects shipping operations from cyber threats targeting vessel systems, networks, and critical infrastructure. It helps companies identify vulnerabilities, manage fleet cyber risk, and improve cyber resilience through suitable solutions from specialized providers. Strong security planning supports safer operations and better decision-making while addressing cybersecurity compliance requirements across maritime environments.
How do maritime cyber security services protect vessel OT systems?
Maritime cyber security services support vessel OT protection by connecting businesses with providers offering assessments, monitoring, and security solutions. These solutions help improve asset visibility, identify weaknesses, and reduce risks affecting operational systems. Proper OT cybersecurity practices help maintain reliable vessel operations while supporting cyber resilience and ongoing risk management.
What compliance standards apply to maritime cyber security in the United States?
U.S. maritime operators may be subject to Coast Guard cybersecurity requirements under 33 CFR Part 101 when operating covered MTSA-regulated vessels, facilities, or offshore facilities. Depending on the vessel’s flag, class, construction date, and operations, additional international requirements may include IMO MSC.428(98), the ISM Code, and IACS UR E26/E27. A maritime cybersecurity assessment can identify which requirements apply and the controls, documentation, training, and response procedures needed for compliance.
How much do maritime cyber security services typically cost?
The cost of maritime cyber security services depends on factors such as fleet size, vessel complexity, required assessments, OT security needs, and compliance goals. Businesses can evaluate different provider options based on operational requirements, security priorities, and the level of support needed for their maritime environment. Pricing varies according to specific needs.
Can cyber security services protect an entire fleet, not just a single vessel?
Yes, maritime cyber security services can support entire fleets by addressing security needs across multiple vessels, connected systems, and operational locations. Suitable providers can help assess fleet cyber risk, improve asset visibility, and recommend solutions based on technology environments, compliance requirements, and security priorities across different maritime assets.
What is the difference between IT and OT security on a vessel?
IT security focuses on protecting data, applications, and communication networks, while OT cybersecurity focuses on systems controlling physical operations and vessel processes. Both areas matter because modern ships rely on connected technologies. Effective security planning helps protect vessel systems, maintain operations, and reduce risks across maritime environments.
