OSINT tools to monitor the Strait of Hormuz
The Strait of Hormuz is one of the most important chokepoints in the world economically, militarily, and politically.
Around 20 to 25% of the world’s oil supply passes through this narrow strait.
Major oil exporters like Saudi Arabia, Iran, Iraq, Kuwait, and United Arab Emirates rely on it.
It’s also critical for liquefied natural gas (LNG), especially exports from Qatar.
If the strait is disrupted, global oil prices can spike immediately.
Due to the conflict between Iranian, Israel and USA. The situation remains unclear.
The vessels are not travelling through the Strait Hormuz.
Monitoring the Strait of Hormuz using OSINT relies on combining maritime tracking, satellite imagery, news, and geopolitical analysis tools. Here are the main categories and widely used tools:
1. Vessel Tracking (AIS Data)
These tools track ships in real time using AIS (Automatic Identification System), which is crucial for monitoring oil tankers and naval activity.
The MarineTraffic is a commercial online ship-tracking and maritime analytics platform that visualizes global vessel movements in near real time. It aggregates data from a vast community AIS (Automatic Identification System) receiver network plus satellites, serving everyone from hobby ship-spotters to logistics, insurance, and energy companies.
The VesselFinder is an online and mobile software platform providing real-time Automatic Identification System (AIS) vessel tracking and maritime analytics. It enables users to view ship positions, voyage details, and port activity globally, serving both casual users and maritime professionals. Its open-access approach and map-based interface have made it one of the most visited AIS tracking tools worldwide.
2. Satellite Imagery Platforms
The Satellite Imagery Platforms can be used to verify activity even when AIS is turned off (dark ships) such as:
Detecting ship (clusters)
Monitoring military buildup or port congestion
Oil spills or maritime incidents
Google Earth is a geospatial visualization tool developed by Google that displays a 3D representation of Earth based on satellite imagery, aerial photography, and GIS data. It allows users to explore geographic information, view terrain and buildings in three dimensions, and access historical imagery across the globe.
satellites.live is a free web-based satellite tracking tool that lets you visualize and follow objects orbiting Earth in near real time.
it’s like a radar screen for space, showing what’s flying above Earth right now.
3. Radio & Signal Monitoring
WebSDR is an online software platform that allows multiple users to listen simultaneously to a wide range of radio frequencies through a shared software-defined radio (SDR) receiver. It provides real time access to radio spectrum data via a web browser, enabling remote tuning, demodulation, and listening without specialized hardware.
AIS Dispatcher is a Windows-based software tool used to decode, filter, and forward Automatic Identification System (AIS) data from ship transponders and receivers. It acts as an intermediary between AIS receivers and data servers or clients, enabling flexible routing of real-time vessel traffic information across multiple network destinations.
Monitoring the Strait of Hormuz with OSINT is about layering multiple data sources no single tool is enough. The most reliable insights come from combining ship tracking, satellite imagery, and real time reporting.
