Tessera Defense and Homeland Security Inc. announced on November 9, 2026, that its wholly owned subsidiary Zorronet Ltd. has expanded its strategic collaboration with D4P group s.r.o. to cover homeland security and critical infrastructure protection across the European Union, with a focus on countering unmanned aerial vehicle (UAV) threats.

Key Highlights

  • Expanded scope: The collaboration with D4P group s.r.o., a subsidiary of Czech company Samura s.r.o., extends from agriculture and transportation into homeland security and critical infrastructure protection across the EU.
  • UAV focus: The initiative specifically addresses threats posed by unmanned aerial vehicles to military installations, airports, energy facilities and other sensitive locations, according to the filing.
  • Preliminary interest reported: D4P has received preliminary interest in AI-powered security solutions from Czech airports, the national power utility and operators of strategic plants, the company disclosed.
  • Railway safety context: The filing cites EU railway safety authority data showing approximately 1,500 significant railway accidents in 2024, with 750 people killed, 548 seriously injured, and EU-wide accident costs estimated at approximately 3.5 billion euros.
  • Scale comparison: The Czech and Slovak railway networks are described as approximately six times larger than the Israel Railways network, where Zorronet has prior deployment experience.
  • Technology approach: Zorronet's platform uses AI, machine learning and vision language models to fuse data from cameras, radars and other sensors, reduce false alarms and automate responses without requiring wholesale system replacement, according to the filing.

Zorronet and D4P Broaden Scope to EU Homeland Security and Critical Infrastructure

According to the filing, the expanded collaboration builds on an initial arrangement announced in July 2026 that concentrated on AI vision-based agricultural pest management and protecting transportation infrastructure from wildlife and trespassers. Under the new scope, Zorronet will provide its AI-powered operational intelligence solution, while D4P will lead business development, sales and customer engagement across its territory and provide local implementation and support.

The company disclosed that the initiative comes as European governments increase their focus on protecting essential infrastructure. The filing references the European Commission's issuance of new guidance on critical infrastructure resilience in July 2026, emphasizing prevention, physical protection and coordinated response, as well as the EU's Critical Entities Resilience Directive, which the filing describes as establishing a framework for strengthening resilience across essential sectors including energy and transportation.

The filing also notes that D4P has identified potential opportunities with police and fire departments in the region, where Zorronet's platform could provide command centers with a single real-time operating picture, detect fires and intrusions early, and help dispatch units faster. Michael Oster, CEO of Tessera, stated in the filing that the expanded collaboration "aligns Zorronet's AI-driven physical security capabilities" with Europe's critical infrastructure resilience priorities. Idan Wasserman, CEO of Zorronet, cited the company's deployment with Israel Railways as demonstrating "the value of integrated, AI-powered security." The filing identifies NYSE American:HLSQ as the trading symbol for Tessera Defense and Homeland Security Inc.
