Dedrone is a leader in airspace security. With more customers around the world than any other airspace security company, we enable our clients to protect people, property, and information from the threat of drones, while enabling the “good” drones to take off (pun intended). The simple fact is that no security company can build a barrier strong enough or high enough to protect from a drone, so we need a tech solution to protect us from the persistent and escalating drone threat. At the same time, the “good” drones will dramatically improve our lives and increase GDP by completing tasks like acting as first responders, delivering medical supplies and retail packages, and more. By combining advanced sensor-fusion technology with AI-driven pattern recognition software, our solutions enable early and reliable drone detection, pilot location and advanced warning in the event an unauthorized drone approaches a secured area. Our customers include national governments, public safety agencies, sporting stadiums, prisons, private research facilities, critical infrastructure sites like airports and power plants, data centers, VIPs and more. Drones are the world’s new asymmetric threat to public safety and national security. Dedrone’s dual-use technology was recognized by two major awards this year. The CNBC Disruptor 50 and TIME’s Best Inventions 2023 lists both feature Dedrone as an innovative company disrupting the industry with its breakthrough capabilities and industry-leading customer list. Dedrone is implemented across 31 countries and is used by five of the G-7 nation governments; 190 critical infrastructure sites; 40 airports; 60+ stadiums; 15+ US federal entities and 20+ non-US governments. We actively provide counterdrone solutions for some of the most high-profile events around the world, working closely with over 120 public safety agencies globally. Our technology is also in use on the front lines in Ukraine, and we are proud to support them in their fight to defend their homeland.
