The seabed carries the modern economy. We help you watch it.
Sondra is an intelligence company focused on critical subsea infrastructure — the cables, pipelines and interconnectors that modern life depends on and almost nobody sees.
We bring together data across assets, activity and operational environments so the organisations responsible for this infrastructure can understand what is happening, detect anomalies early and identify emerging risk before it becomes an incident.
Why we exist
Subsea infrastructure has become a frontline concern — and the tools to understand it have not kept pace.
The problem
Cable faults, suspicious vessel behaviour and deliberate interference are rising, while European policy — CER, NIS2, the EU Action Plan on Cable Security — increasingly expects operators and authorities to demonstrate situational awareness and coordinated response.
Our answer
An intelligence layer above the sensor and beyond the alert: correlating AIS, SAR, RF and other signals into assessed events, supporting attribution, and preserving evidence that stands up to scrutiny from operators, insurers and authorities alike.
How we work
Decision support, not hype. We are deliberate about what Sondra is — and what it is not.
Evidence first
Every assessment is traceable to the signals behind it, so conclusions can be examined, challenged and defended.
Built with operators
The platform is shaped by the people who run cables, pipelines and offshore assets — not by abstract dashboards.
Clear boundaries
Sondra supports the operational requirements of resilience frameworks. It does not certify compliance, give legal advice, or replace physical protection.
