Protecting Europe's Critical Undersea Infrastructure
our mission
Ireland sits at the gateway to Europe's digital economy. Nearly 75% of transatlantic submarine cables passing through, or adjacent to, Irish territorial waters - communications, financial transactions, government systems. These cables are increasingly vulnerable, and largely unmonitored.
Sentrell is enabling the intelligence capability to change that.
The Surveillance Gap
Europe's submarine cable network is critical infrastructure without a coherent monitoring strategy. Recent incidents in the Baltic and North Sea have demonstrated the vulnerability. The capability gap is known, but solutions have been slow to materialise.
The challenge isn't just detection — it's building persistent maritime domain awareness across vast ocean areas, correlating sensor data from multiple sources, and delivering actionable intelligence to the operators who need it.
This requires new approaches: autonomous systems that can maintain presence where crewed vessels cannot, AI that can process and fuse sensor data at scale, and architectures designed for degraded and contested conditions.
What We’re Building
Persistent Awareness
Enabling long-duration autonomous maritime surveillance in the North Atlantic and European waters.
Edge Intelligence
AI systems designed to operate with limited connectivity, making decisions where bandwidth is constrained.
Sensor Fusion
Integrating radar, AIS, sonar, and other data sources into unified operational pictures.
Iteroperability
Architectures built for coalition operations and integration with existing naval systems.
We work with autonomous platform providers and naval stakeholders to deliver capability that doesn't exist today.
European. Irish. Independent.
Sentrell is headquartered in the West of Ireland. We're building for the European defence market, with Ireland's strategic position, geographic and political, at the centre of our approach.
Ireland hosts critical communications infrastructure for the entire European Union. Protecting it is an Irish interest, a European interest, and an opportunity for Irish enterprise to contribute to collective security.
We're engaged with government and industry partners on near-term capability development, and positioned to participate in European Defence Fund initiatives as the EU scales investment in maritime security.
working with us
We're currently in structured engagement with a small number of government and industry partners.
