Guardian RF
The rise of low-cost commercial drones has introduced a new class of asymmetric threats to U.S. national security. Off-the-shelf platforms now deliver ISR, contraband, or payloads with precision, while operating below radar coverage and beyond line-of-sight. These systems—often costing under $1,000—are capable of neutralizing multi-million-dollar defense assets. For drone detection to be viable at scale, sensors must achieve cost parity with the threat. In response, the Department of Defense est

sourceGuardian RF is classified as Cybersecurity from source descriptions and fund-directory context. Similar companies below are ranked from offline product facets and meaningful description overlap; category and source affiliation can only strengthen an existing product match. For lookup-created rows, the profile starts as pending enrichment until deeper source collection runs.
Local clusters rerank extracted product concepts and description terms. The generated graph remains the fallback for sparse descriptions: offline reciprocal product-similarity graph: extracted concepts + description terms + bounded category/affiliation boosts. Minimum fallback score: 0; max competitors: 6.

Milliray
match 93We make radars that can see small drones. As drones evolve faster than air defenses, detection has fallen behind. Even $50 drones now present a major threat to airports, critical infrastructure, and front-line defense. We solve this by building high-frequency radar systems, designed from the ground up to detect even the most challenging low-signature targets. This allows us to identify and track nano drones like no other solution, letting you know what's truly in your airspace.

Perseus Defense
match 65Perseus Defense is building a mass-manufactured Counter UAS solution for the Department of Defense and Department of Homeland Security. Current solutions are one-to-one, too dangerous for use on U.S. soil, and orders of magntiude more expensive than the threats they defeat. Our self-guided missile platform is man-portable and multi-domain capable. It senses, engages, and eliminates threats with drastically reduced cost per engagement over existing kinetic solutions. Solving this critical nationa

Tenet Industries
match 59Tenet Industries is building low-cost mass-producible defense systems, starting with attack drones. We're using design-for-manufacturing and first principles to reimagine how a defense product is developed and manufactured. We begin with the manufacturing, then solve all the inefficiencies and difficulties in the firmware/software. This allows us to hyperscale production in multiple defense categories such as strike drones, loitering munitions, jammers, radars, etc. Our first product is a kamika

Arlo Industries
match 57Arlo Industries is building a network of sensors that precisely tracks stealthy drones and aerial threats better than radars. This capability does not exist yet because traditional radars are built on past war doctrines designed to protect single, centralised assets. Modern warfare, however, demands wide-area, persistent coverage that is both passive and economically scalable. By utilising a mesh architecture, Arlo Industries unlocks unprecedented asymmetric economics. The network is fundamental

Traversal Networks
match 51Traversal Networks develops a new form of Network Intrusion Detection System designed to catch unknown threats. The Lateral Threat Detector appliances are easily installed on your corporate network. These analyst-assisted sensors learn traffic patterns on each of your network segments and detect lateral exploitation, backdoors, bots, malware, and network reconnaissance. The Traversal Networks operate on four different platforms: learn, reputation, machine learning and search. Traversal Networks
