Cybersecurity has never simply been about preventing attacks. For maritime organisations, it is about maintaining safe, reliable vessel operations across fleets that operate globally, often with intermittent connectivity, ageing technology and limited IT resource.
Many shipping companies are already working towards compliance with the IMO cyber risk management requirements and preparing for IACS Unified Requirements E26 and E27. NIS2 adds another important consideration, placing greater emphasis on governance, accountability and the ability to demonstrate effective cybersecurity controls.
While much of the discussion surrounding the EU’s Network and Information Security Directive (NIS2) has focused on compliance deadlines and regulation, the directive is really about operational maturity.
Not every shipping company will meet NIS2’s mandatory compliance thresholds, and several member states are still finalising national transposition. Classification as an essential or important entity depends on sector, size and turnover, not on being in the maritime industry alone. But the underlying practices, knowing what’s on your network, who can access it, and how you’d respond if something goes wrong, hold up as good practice regardless of which side of that line an organisation falls on.
It shifts cybersecurity from something organisations say they do to something they can prove.
For maritime IT teams, that presents a challenge that goes well beyond regulation.
NIS2 compliance starts with visibility
The shipping industry has become significantly more connected over the last decade.
Today’s vessels routinely exchange operational data with shore. Crew welfare depends on reliable internet connectivity. Performance monitoring systems, planned maintenance software, remote diagnostics, emissions reporting, class documentation and commercial applications all rely on data moving between ship and shore.
At the same time, fleets continue to operate a combination of modern applications alongside legacy systems that may have been installed many years ago.
The result is an IT environment that is constantly evolving.
The question for operators is no longer simply whether systems are secure.
It is whether they know exactly what systems exist across the fleet in the first place.
Without that visibility, every other cybersecurity process becomes more difficult.
You cannot patch systems you cannot see.
You cannot protect assets you do not know exist.
You cannot demonstrate compliance if you cannot accurately describe your own environment.
Why NIS2 is different for maritime IT teams
Many discussions around NIS2 assume organisations operate from offices with permanent connectivity, predictable maintenance windows and large internal IT departments.
Shipping is different.
Vessels operate around the world, often with intermittent satellite connectivity and limited opportunities for maintenance. Equipment frequently remains in service for many years, while software updates must be carefully planned around operational schedules rather than simply deployed overnight.
Meanwhile, the demands placed on maritime IT teams continue to grow.
Most organisations are not increasing their IT headcount at the same rate as their digital infrastructure.
The expectation, however, is exactly the opposite. As more systems become connected, IT teams are expected to maintain greater visibility, respond more quickly to vulnerabilities and provide stronger evidence that appropriate controls are in place.
For many organisations, the workload is increasing faster than the available resource.
NIS2 is about evidence, not intention
One of the biggest misconceptions surrounding NIS2 is that it introduces entirely new cybersecurity requirements.
In reality, most organisations will already recognise the controls being discussed:
- Asset inventories
- Access management
- Patch management
- Incident response
- Business continuity
The difference is that these activities are no longer regarded simply as good practice.
They are becoming auditable operational processes.
If an incident occurs, organisations may need to demonstrate not only that policies exist, but that they were followed.
Instead of asking whether a company has a vulnerability management process, regulators increasingly want to know:
- Which systems were vulnerable?
- What action was taken?
- When was that action completed?
Good cybersecurity is becoming measurable cybersecurity.
Continuous visibility is becoming an operational capability
As fleets become larger and more digitally connected, manual methods of tracking IT assets become increasingly difficult to maintain. Spreadsheets quickly become outdated as devices are added, software changes, remote updates take place and configurations evolve.
Visibility should no longer be viewed as an annual audit exercise.
It needs to become a continuous operational capability.
Understanding what exists across the fleet, where vulnerabilities are located and how systems are connected allows IT teams to prioritise risk instead of simply reacting to it.
It also provides something equally valuable: confidence.
When regulators, customers or insurers ask questions about cybersecurity, organisations with continuous visibility are in a far stronger position to answer them.
This is where automated asset discovery becomes invaluable. Rather than relying on manual records, maritime organisations can continuously monitor their fleet, identify connected assets and understand where vulnerabilities exist.
Solutions such as GT Hub are designed specifically for this purpose, providing real-time visibility across vessel and shore-based IT environments, helping organisations understand their cyber posture while building the evidence increasingly expected by modern regulatory frameworks.
Technology should simplify cybersecurity
There is a temptation to see new regulations as requiring more software, more dashboards and more administration.
In reality, the objective should be the opposite. Technology should reduce operational burden, not increase it. The most valuable security platforms are not those that generate the largest number of alerts.
They are the ones that help IT teams understand where attention is genuinely needed, reduce manual effort and provide clear evidence of what is happening across the fleet.
Visibility, however, is only the first step.
Once vulnerabilities have been identified, organisations also need efficient ways to remediate them and maintain secure, compliant systems without creating additional operational complexity.
For maritime organisations managing growing digital estates with relatively small teams, that distinction matters.
Cyber resilience also depends on people
Technology alone cannot eliminate cyber risk.
Many successful cyber incidents still begin with an unsuspecting user clicking a malicious link, responding to a phishing email or unintentionally exposing sensitive information.
Building cyber resilience therefore requires more than technical controls. It requires people to recognise threats and respond appropriately.
Regular security awareness training and phishing simulations help reduce human risk while supporting the organisational measures expected by frameworks such as NIS2.
Solutions like GT Aware help shipping companies strengthen their human firewall through continuous awareness training, simulated phishing campaigns and practical education designed specifically for today’s evolving cyber threats.
Preparing for the future
NIS2 will undoubtedly drive more conversations about compliance, governance and reporting across the maritime industry over the coming years.
Those conversations are important.
But for most maritime organisations, the first questions are much simpler.
Can you confidently describe your fleet’s IT environment?
Do you know every connected asset?
Do you know which systems require attention?
Can you demonstrate that vulnerabilities are being managed?
Can your people recognise and respond to today’s most common cyber threats?
If the answer to those questions is yes, compliance becomes considerably easier.
If the answer is no, that’s where the work should begin, whether or not NIS2 applies to you directly.
Ultimately, the directive is not asking organisations to become perfect.
It is asking organisations to become visible, accountable and resilient.
In an increasingly connected maritime industry, those capabilities are rapidly becoming some of the most important operational advantages an IT team can possess.
