Maritime Cybersecurity,
Why It Matters Now
Ships are more connected than ever.
And more vulnerable than ever.
Real-world incidents, tightening regulations,
and the limits of conventional IT security —
why maritime-specific cybersecurity is essential.
The Double Edge of Digital Transformation —
An Expanding Attack Surface
The maritime industry is undergoing a massive digital transformation. Smart ships, performance monitoring, predictive maintenance — all driving an exponential increase in onboard data traffic.
But this connectivity is a double-edged sword. As OT systems integrate with shore-side IT networks via satellite communications, the attack surface available to cyber adversaries has expanded dramatically.

Compliance Is No Longer Optional
Since July 2024, IACS UR E26/E27 regulations have been mandatory for all newbuilds.
Non-compliance means delivery delays, failed surveys, and lost contracts.
