Do you trust that most companies are effectively securing their critical digital infrastructure?

Eighty-seven percent of maritime industry respondents reported a significant operational technology (OT) cyber incident in the last 12 months. This finding comes as connected shipboard systems face increasing exposure to global cybersecurity threats.

Why it matters

Connected shipboard systems have growing exposure to cybersecurity incidents, leaving critical operational infrastructure vulnerable. Organizations with better visibility into their OT environments are able to identify threats four times more effectively.

Only 21% of surveyed organizations maintain a complete inventory of their OT assets, while 33% have fully integrated these systems into a centralized security operations center. Additionally, significant incidents caused an average of 16.2 hours of downtime.

The players

Honeywell

This multinational conglomerate produces the 2026 Operational Technology Cybersecurity Benchmark Report.

NAVTOR

The company provides e-Navigation solutions and recently addressed vulnerabilities in its data gateways.

Marlink

This provider of smart network solutions recently expanded its portfolio by launching a new OT security service.

The details

Increasing remote access and high-capacity connectivity now expose equipment originally designed to operate in isolation. While 88% of respondents claim their cybersecurity programs are mature, only 20% continuously monitor connected IoT equipment.

Timeline

  1. Earlier 2026: NAVTOR patched high-severity vulnerabilities in legacy NavBox data gateways.

  2. August 2026: Marlink launched a new OT security service.

  3. September 22, 2026: Honeywell released its 2026 cybersecurity benchmark report.

  4. September 28, 2026: Date of article publication.

The Tech Race

The transition toward digitalization in global shipping replaces isolated legacy systems with interconnected networks that demand advanced protection. This shift forces maritime operators to accelerate their adoption of centralized security operations to compete with the broader industrial sector.

Increased cybersecurity risks may lead to higher service costs and potential delays as maritime companies invest more heavily in mandatory security upgrades. Users of maritime logistics services might see longer lead times if ship operators undergo mandatory system maintenance to address these vulnerabilities.

The takeaway

Companies should prioritize building a comprehensive inventory of all operational assets to increase threat identification effectiveness. With 99% of leaders expecting AI to reshape security soon, firms must prepare for automated defenses to become a standard industry requirement.
