Common Questions
What is Windward and what do they do?
Windward is an Israeli maritime intelligence company that uses AI to track vessel behaviour, AIS spoofing, sanctions evasion, and shadow fleet movements. Its data is used by EU policymakers, OFAC, and conflict reporters.
How are sanctioned tankers getting through the Hormuz blockade?
Windward documented 14 State Department-sanctioned dark-fleet vessels near Hormuz on 12 April using the identities of scrapped ships to evade enforcement. The vessels exploit CENTCOM's carve-out for non-Iranian-port traffic.Source: Windward
How did the EU track Russia's shadow fleet?
Windward's registry analysis found Sovcomflot had reflagged 56% of its fleet to Russia's own registry. This evidentiary analysis underpinned the EU's March 2026 shadow-fleet sanctions package.Source: Windward / EU
How much AIS spoofing is happening in the Persian Gulf?
Windward identified 92 AIS denial zones and 44 GPS jamming zones in the Persian Gulf as of 5 March 2026, mapping the electronic warfare environment affecting commercial navigation.Source: Windward
What is Windward and how does it track ships?
Windward is an Israeli maritime intelligence company founded in 2011, listed on the London Stock Exchange. Its platform combines AIS vessel-tracking, satellite imagery, and machine-learning to detect sanctions evasion, shadow fleet movements, and anomalous vessel behaviour. It was founded by Ami Daniel and Matan Peled.Source: Windward / LSE filings
What has Windward found about Hormuz traffic during the 2026 conflict?
Windward documented 92 AIS denial zones and 44 GPS jamming zones in the Persian Gulf by March 2026. On 19 April it logged only 3 Hormuz transits — the lowest since the blockade — with 7 VLCCs clustered near Chabahar. On 23 April it confirmed the first completely AIS-blank transit day in the strait's history.Source: Windward
How has Windward been used in Russia sanctions enforcement?
Windward documented that Sovcomflot reflagged 56% of its fleet to Russia's own registry to evade Western sanctions. The EU cited Windward's reflagging analysis as justification for its March 2026 shadow-fleet sanctions package.Source: Windward / EU Council

Background

Windward is an Israeli maritime intelligence company founded in 2011 by Ami Daniel and Matan Peled, listed on the London Stock Exchange (AIM) since December 2021. Its platform fuses AIS vessel-tracking data, satellite imagery, and machine-learning behavioural models to flag sanctions evasion, illicit ship-to-ship transfers, and anomalous vessel behaviour at scale.

Across both active conflicts Windward covers, its data has become primary evidence for policymakers. In the Strait of Hormuz, Windward mapped 92 AIS denial zones and 44 GPS jamming zones as of 5 March 2026, documenting the electronic warfare environment strangling commercial navigation. By 12 April, the company documented 14 State Department-sanctioned dark-fleet vessels near Hormuz using the identities of scrapped ships to evade enforcement. On 19-20 April, Windward logged only three Hormuz transits — the lowest since the blockade began — alongside seven VLCCs clustered near Chabahar with combined 14 million barrel capacity, then on 23 April confirmed the first completely AIS-blank transit day in the strait's recorded history. On 24 April, Windward logged 9 transits and a 13% dark-activity surge. In the Russia-Ukraine war, Windward's registry analysis documented that Sovcomflot reflagged 56% of its fleet to Russia's own registry, supplying the evidentiary backbone for the EU's March 2026 shadow-fleet sanctions package.

Windward occupies an unusual position: a private company whose commercial intelligence product directly shapes sanctions enforcement and conflict reporting in two simultaneous major conflicts. Its data appears in EU policy documents, news wires, and government briefings simultaneously, raising questions about accountability, methodology transparency, and the role of for-profit maritime analytics in determining which ships are targeted.
