An independent cybersecurity review has found no significant security flaws in two popular DJI drone models, adding fresh momentum to the Chinese manufacturer’s efforts to challenge restrictions imposed in the United States.

The assessment, carried out by US-based cybersecurity firm OnDefend between October 2025 and March 2026, examined the DJI Air 3S and DJI Matrice 4E drones along with their associated controllers. According to the report, investigators found no evidence that data was being transmitted outside the United States and identified no hidden mechanisms that could allow the devices to be remotely controlled or compromised.

While the review noted a number of minor security considerations, OnDefend concluded that these findings were consistent with those commonly found in complex electronic systems and did not pose a meaningful threat to safe operation or data security. DJI said software updates are already being developed to address some of the observations raised during testing.

The findings arrive as DJI continues to contest restrictions placed on Chinese-made drone technology by US authorities. The company has submitted a petition seeking reconsideration of its regulatory status and has also launched legal action challenging the restrictions.

DJI argues that independent testing supports its long-standing position that its products operate securely and that concerns regarding data handling and national security have not been substantiated by technical evidence. The company maintains a significant user base among commercial operators, emergency services and agricultural businesses despite a sharp decline in exports to the US market following recent regulatory changes.
