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

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 the Iran-conflict and Russia-Ukraine tracks, Windward's data has become primary evidence for policymakers. In the Strait of Hormuz, the company 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, it documented 14 State Department-sanctioned dark-fleet vessels near Hormuz using the identities of scrapped ships . By 20 May, Windward logged a 600 per cent AIS transponder deactivation surge and only two commercial transits against a pre-crisis baseline of roughly 95 per day. On 21 June 2026, as CENTCOM logged 55 merchant vessels transiting, Windward said the IRGC closure declaration and the vessel data 'were pointing in different directions' . When General Licence X authorised Iranian oil sales on 22 June, the firm described the 12-transit day as a 'late-blockade baseline closer to wartime dark-fleet running' rather than a reopening . In the Russia-Ukraine war, Windward's registry analysis documented that Sovcomflot reflagged 56 per cent of its fleet to Russia's own registry, supplying the evidentiary basis for the EU's March 2026 shadow-fleet sanctions package.

Windward occupies an unusual position: a private company whose commercial 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.

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.

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

Windward is an Israeli maritime AI company founded in 2011 and listed on the London Stock Exchange. It tracks AIS vessel movements, dark-fleet activity, and sanctions evasion globally.Source: entity background
Why does Windward say the Strait of Hormuz is not really open?
After General Licence X on 22 June, only 12 cargoes cleared Hormuz, down from 55 on 20 June. Windward described the 22 June figure as a 'late-blockade baseline' rather than a reopening.Source: Lowdown event 4450
How does Windward's data differ from official US government claims about Hormuz?
On 21 June, CENTCOM logged 55 transits and JD Vance said he saw 'no evidence the strait is closed'. Windward said the IRGC closure claim and the vessel data were 'pointing in different directions', stopping short of either government narrative.Source: Lowdown event 4425
What did Windward find about Russia's shadow fleet?
Windward documented that Sovcomflot reflagged 56 per cent of its fleet to Russia's own registry, evidence that underpinned the EU's March 2026 shadow-fleet sanctions package.Source: entity background
