This article focuses on improving the information security of industrial enterprises through the automation of data transmission processes. As a solution, an autonomous unmanned aerial vehicle (UAV) equipped with three microcontrollers is proposed to handle flight control, data processing and transmission and information protection. The system utilises infrared data transmission channels, hardware encryption and a mechanism for the physical destruction of the storage medium, ensuring a high level of protection against cyberattacks and data breaches. The drone’s architecture is isolated from corporate networks and features mobility and autonomy, making it effective in environments with limited infrastructure. The modular design of the device allows for adaptation to various application scenarios. The research results demonstrate that the proposed solution provides reliable and secure data transmission, enhancing the resilience of enterprises to modern cyber threats.
