Be Holder

The BEHOLDER Horizon Europe project aims to protect citizens by developing an integrated, IoT-based detection system for chemical, biological, radiological, nuclear, and explosive (CBRN-E) threats. Launched in June 2025 and running for three years, this EU-funded initiative brings together 14 partners from 7 European countries, coordinated by the Dutch Institute for Safe & Secure Spaces (DISSS). By its final stage in May 2028, BEHOLDER will deliver a scalable, interoperable platform designed to enhance real-time detection, assessment and response capabilities—helping to safeguard public spaces across Europe.

Cities today face growing risks from CBRN-E threats that can endanger public safety. Unfortunately, many current detection technologies operate in isolation, lacking integration with smart city systems and limiting their impact. BEHOLDER tackles this challenge head-on by building a flexible, vendor-neutral ecosystem that integrates seamlessly with existing urban infrastructure—such as SmartCity platforms and SmartFurniture networks—without compromising the look and feel of public spaces.
