Port approaches and waterside activity monitored for port authorities

Industry Solutions

Port Authorities

Waterside visibility, arrival integrity, and anomaly monitoring across your approaches and anchorage.

The Problem

The approach is where the surprises come from.

Ports manage what arrives: vessels whose declared identity, position, and history shape berthing, inspection, and enforcement decisions. A spoofed approach, a hull whose identity does not match its papers, or a caller with an undeclared history of dark legs and transfers puts that decision chain at risk, and conventional systems accept the declaration at face value.

Theia gives port and coastal authorities an independent check on every approach: identity verified against observation, the vessel’s real history surfaced before it berths, anomalies flagged across the anchorage, and the basis to prioritize inspections where the risk actually sits.
