Superyacht Cybersecurity: Securing Satellite Connectivity at Sea
Good news first: thanks to LEO satellite services, superyachts no longer have to struggle with connectivity. The challenge now is control.
At MTN, we see this pattern across fleets. Connectivity has moved forward quickly, while security has often been added later, often in pieces. The result is predictable: more complexity, broader access, and less visibility into where the real risks sit.
As a result, the conversation has shifted. The question is no longer how to get online, but how to maintain control once that connectivity is in place.
Maritime Cyber Threats Are Increasing
The risk in maritime cybersecurity is not new. The 2017 NotPetya attack disrupted Maersk across more than 600 sites and 76 ports, resulting in losses of approximately $300M and requiring a large-scale rebuild of systems and infrastructure. More recent reporting shows cyberattacks across maritime operations continuing to rise through 2026, largely driven by ransomware, compromised credentials, and unauthorized access.
The key difference today is that attackers don’t need physical access or close proximity, they just need connectivity.
Where Superyacht Cyber Risk Builds Onboard
On yachts, the issue is rarely one obvious vulnerability. It’s what builds up over time.
As new systems are added, vendor access is enabled, and networks expand, the overall environment becomes more complex. In many cases, those changes are made incrementally and without a full reassessment of how everything connects. Over time, visibility decreases, dependencies increase, and control becomes more difficult to maintain.
That is typically where meaningful cyber exposure develops.
How MTN Manages Superyacht Cybersecurity
At MTN, cybersecurity is not treated as something added after the fact. It is built into how the connectivity environment is designed, deployed, and managed. Here is how MTN secures superyachts:
- Risk assessment: Full visibility into systems, access, and vulnerabilities
- Penetration testing: Validation of real-world exposure
- Continuous protection: Segmentation, monitoring, and policy enforcement
- Crew training: Reduced exposure from human error
This is not a one-time exercise. As systems, connectivity, and operational requirements evolve, the security model needs to evolve alongside them.
What Technical Managers Should Focus On
In practice, maintaining control comes down to a few core questions. Technical managers should have a clear understanding of the following:
- Do we know exactly what’s connected?
- Do we control who can access it?
- Are critical systems separated from everything else?
- Do we know what happens if something goes wrong?
Where those answers are unclear or incomplete, risk is typically being assumed rather than actively managed.
Next Step: Understand Your Current Exposure
For most vessels, the first step is simply getting a clear view of the current environment.
