Regulus Cyber has raised approximately $10M in total funding, including a disclosed ~$4M Series B round, indicating sustained investor backing for its GNSS security and counter‑UAS products.

Regulus publicly unveiled its Ring counter‑UAS system (including the Ring R1 variant with RF detection) as a GNSS spoofing‑based effector targeting Class 1–2 UAS, with modes to stop or divert drones and support for GPS, Galileo, GLONASS, and BeiDou.

The company developed the Pyramid GNSS cybersecurity platform, including Pyramid GPS SP and Pyramid CSM modules, to detect spoofed GPS signals and protect communications for drones and autonomous vehicles.

An F2 Venture Capital profile describes Regulus Ring as an 'Iron Dome'–like counter‑drone solution adopted by military divisions in Israel and the US, implying operational defense partnerships and field integration.

Enforce Tac exhibitor information states that Ring C‑UxS is fully operational at TRL9 with hundreds of systems deployed and dozens of confirmed combat kills against aerial and maritime threats, demonstrating real-world operational validation.

An investor article reports that Regulus rapidly expanded operations in the first weeks of the recent war in Israel to meet increased counter‑drone demand, suggesting surge capacity and scaling of deployments.

Company profile data indicates a headcount of roughly 25–32 employees and sub‑$5M annual revenue, reflecting a compact, specialist team structure focused on GNSS security and C‑UAS solutions.
