D-Fend

D-Fend Solutions was founded in 2017 by Ziv Knapp, Yaniv Benbenisti, and Assaf Monsa. The company operates from its headquarters in Ra'anana, Israel, as a privately held entity. D-Fend develops counter-drone (C-UAS) technology, specifically focusing on RF-based cyber-takeover systems.

The primary product is EnforceAir, a system designed to detect, identify, and mitigate rogue unmanned aerial systems (UAS). Unlike traditional counter-drone methods that rely on kinetic intercepts (shooting drones down) or RF jamming (which disrupts local communications), EnforceAir uses protocol reverse engineering and radio frequency (RF) analysis to take control of the target drone and land it safely in a predefined zone. The system is sold to military units, border security, law enforcement, and critical infrastructure operators, including publicly acknowledged deployments with the US Department of Defense, Homeland Security, and the FAA.

EnforceAir is the flagship offering, deployed in multiple configurations including vehicle-mounted, fixed-site, and tactical man-portable setups. The software operates on SDR (Software Defined Radio) hardware.

D-Fend competes in the counter-UAS market against companies like Dedrone, DroneShield, and Fortem Technologies. Its specific positioning hinges on its non-jamming, non-kinetic approach, which is highly suited for urban or sensitive environments like airports where collateral damage or spectrum disruption is unacceptable.

The company's primary R&D center and global headquarters are located in Ra'anana. The R&D organization heavily targets engineers with backgrounds in embedded systems, DSP (Digital Signal Processing), software-defined radio, and low-level protocol research, frequently recruiting from IDF intelligence and technology units.
