DefSecIntel Solutions

DefSecIntel Solutions is an Estonian defense technology firm headquartered in Tallinn, established in 2017. The company specializes in counter-unmanned aircraft systems (C-UAS) and autonomous surveillance platforms, positioning itself as a provider of integrated security solutions for defense forces, border authorities, and critical infrastructure operators. Its operational philosophy is rooted in translating lessons learned from the conflict in Ukraine into deployable hardware and software architectures for European security.

The company’s primary product is the EIRSHIELD, an integrated, vehicle-based multi-layer C-UAS system. The platform is designed to detect, track, classify, and neutralize hostile aerial threats through a combination of radar, radio frequency (RF), electro-optical/infrared (EO/IR), and acoustic sensors. These sensors feed into an AI-powered command and control (C2) architecture that coordinates multiple soft- and hard-kill effectors. A key feature of the EIRSHIELD system is its open architecture, which allows for the plug-and-play integration of third-party sensors and interceptor solutions. This interoperability enables end-users to connect existing capabilities into a common operating picture, facilitating a rapid response chain from detection to interception. The system is marketed as NATO-certified and suitable for mobile, transportable, and static deployments in demanding environments.

In addition to C-UAS capabilities, DefSecIntel develops automated surveillance systems for persistent situational awareness across land, border, coastal, and maritime environments. These systems utilize AI-assisted command and control to manage large volumes of sensor data, aiming to reduce personnel exposure and improve response times in difficult terrain and harsh weather conditions. The company states that its surveillance solutions are currently deployed to protect the external borders of the European Union and NATO’s Eastern Flank.

The firm’s development cycle is characterized by rapid iteration based on operational feedback from Ukraine. DefSecIntel emphasizes that its systems are not merely conceptual but are built for immediate operational capability. The company highlights the integration of best-in-class sensors with its proprietary C2 middleware, designed to reduce false alarms and accelerate decision-making for operators. By combining detection, decision-making, and interception into a single workflow, DefSecIntel aims to lower the burden on operators while providing scalable and affordable defense solutions. The company’s tagline, “Makes the EOS C-UAS counter-drone platform and autonomous surveillance towers used by Baltic forces,” reflects its regional focus and the specific nature of its hardware offerings.
