DJI has been busy addressing both the technical infrastructure of drone operations and the geopolitical scrutiny surrounding its data security practices. The company is currently navigating a complex regulatory environment in the United States while simultaneously expanding its enterprise hardware ecosystem.
Independent Audit Finds No Major Security Risks in Air 3S and Matrice 4E
In a move to address regulatory pressure, DJI recently released the results of an independent security assessment for two of its prominent models: the Air 3S and the Matrice 4E. The evaluation, conducted by the U.S.-based cybersecurity firm OnDefend between October 2025 and March 2026, aimed to provide a technical counter-argument to the company's inclusion on the FCC Covered List.
The assessment included hardware teardowns, silicon-level analysis, and full-spectrum radio frequency scanning. According to the report, the auditors identified zero critical, high, or medium-risk findings. While the investigation did yield ten low-risk findings and thirteen observations regarding application configurations, the core security architecture remained intact during testing.
Data privacy was a central focus of the audit. Testing confirmed that all observed connections from DJI flight control applications resolved to U.S.-based infrastructure. The auditors found no evidence of data transmission outside the United States, nor did they detect any backdoors or unauthorized remote access mechanisms. This data directly competes with security claims made by domestic drone manufacturers like Skydio, which often highlight the risks of foreign-made hardware.
- Scope: Evaluated DJI Air 3S with RC 2 and Matrice 4E with RC Plus 2 Enterprise.
- RF Scanning: Covered frequencies from 1 MHz to 6 GHz.
- Infrastructure: All tested units communicated exclusively with domestic servers.
DJI commissioned this report specifically to challenge its late 2025 designation on the FCC Covered List. The company maintains that technical evidence does not support the security concerns raised by federal regulators.
New O4 Ground Station Expands Enterprise Transmission Capabilities
Beyond its efforts in the security sector, DJI is also expanding its hardware lineup for industrial and enterprise users. The company has launched the DJI O4 Ground Station, a robust transmission hub designed to support wide-area operations and unattended drone missions. This hardware serves as a terrestrial anchor for the O4 transmission system, which is also featured in modern consumer drones like the DJI Mini 4 Pro.
The O4 Ground Station utilizes a 12-antenna array with both horizontal and vertical polarizations. This configuration provides omnidirectional high-gain coverage, allowing for more stable connections in complex environments. To mitigate interference, the station automatically switches between multiple frequency bands, including sub-2 GHz, 2.4 GHz, 5.2 GHz, and 5.8 GHz.
The device operates in two primary configurations to suit different mission profiles:
- Gateway Mode: Connects to DJI FlightHub 2 to extend DJI Dock 3 coverage up to 30 km for remote monitoring.
- Relay Mode: Acts as a signal extender in obstructed areas such as deep valleys or dense urban environments.
On a different front, DJI has built the station for extreme durability. It features an IP67 rating for dust and water resistance and can operate in temperatures ranging from -40°C to 55°C. For off-grid deployments, the station is compatible with DJI Power solar solutions or third-party photovoltaic systems. It also includes a high-gain RTK module that tracks 19 frequencies across five global satellite systems, providing centimeter-level positioning accuracy for precision tasks.
Meanwhile, DJI's software integration remains a priority for the new hardware. The O4 Ground Station supports the MQTT protocol, allowing users to connect third-party Remote ID or ADS-B receivers. This interoperability is essential for enterprise users who must comply with evolving airspace regulations while maintaining proprietary workflows.
The company is also making waves with its focus on maintenance-free operation. The station employs fanless passive cooling and a self-recovery mechanism to ensure long-term stability without manual intervention. This places the O4 Ground Station as a direct competitor to specialized long-range transmission systems from companies like Autel Robotics or senseFly.
As DJI continues to release new enterprise tools, it remains focused on proving its hardware is both technically capable and secure for professional use. These updates suggest a strategy of simultaneous technological advancement and proactive regulatory engagement as the drone industry faces increased scrutiny.
