Estonian defence technology company DefSecIntel Solutions has signed a memorandum with Polish technology company Siltec to pursue deployment of its EIRSHIELD counter-drone system at critical infrastructure and other sensitive sites in Poland.
DefSecIntel and Siltec signed their memorandum while exhibiting at MSPO 2026 in Kielce from September 8 to 11. The companies said the work will combine multi-layer EIRSHIELD architecture and artificial intelligence-assisted command and control with Siltec’s expertise in secure and classified systems, according to Tööstusuudised. The agreement does not disclose a contract value, procurement quantity, delivery schedule or potential customers.

DefSecIntel identified critical infrastructure protection, border security, public safety and other sensitive environments as priority applications. The companies will also examine settings where controlled and non-kinetic responses to unmanned aircraft are required.
The memorandum covers Poland and other NATO markets. The Estonian company described Poland as one of its key strategic markets and linked the cooperation to broader security requirements on NATO’s Eastern Flank.
Jaanus Tamm, chief executive officer of DefSecIntel Solutions, signed the memorandum with Magdalena Kujawa, vice president of Siltec. The agreement provides the Estonian company with a local industrial partner to adapt its counter-UAS architecture to Polish secure-systems requirements.

How the EIRSHIELD architecture works
EIRSHIELD is an integrated, multi-layer counter-unmanned aircraft system. Its architecture can combine radar, radio-frequency, electro-optical and infrared, and acoustic sensors with soft-kill and hard-kill effectors, including interceptor drones.
DefSecIntel positions command and control as the integration layer connecting those components. The company describes it as a plug-and-play architecture designed to integrate existing and new third-party capabilities into a common operating and response chain, rather than tying the system to a single sensor or effector configuration.
Part of a wider European integration strategy
DefSecIntel has previously demonstrated EIRSHIELD with third-party counter-drone technology. In November 2025, the company took part in a demonstration in Latvia with Latvian manufacturer ORIGIN, where an EIRSHIELD radar provided target data for ORIGIN’s BLAZE autonomous interceptor.
The company also signed cooperation agreements with Germany’s ARGUS Interception and Romania’s CARFIL, part of the ROMARM group. The agreement with ARGUS covers integration of the A1-Falke interceptor into the EIRSHIELD architecture, while the cooperation with CARFIL covers integrated counter-UAS capabilities for Romania and the wider region.
