Sunhillo Corporation

What Sunhillo Corporation does

Sunhillo Corporation is a private, employee-owned computer hardware and software company founded in 1991 and headquartered in West Berlin, New Jersey, with a secondary office in San Diego, California. The company designs, manufactures, and sells surveillance data distribution, conversion, and interoperability products for the air traffic control, defense, and unmanned aerial systems (UAS) markets. Its product portfolio is built around the SureLine Software Suite — a proprietary platform supporting over 400 protocol conversion combinations across ASTERIX categories, CD-2, ADS-B (CAT021/023/033/062), and legacy radar formats — which runs on Sunhillo's own hardware appliances including the RICI/Longport/Ventnor serial-to-IP gateways, the Brigantine SGP 1U surveillance gateway processor, and the Margate II ADS-B receiver. Add-on plug-ins (Multi-Track Fuser, Single Sensor Tracker, Virtual Radar) extend SureLine into multi-sensor track correlation, and a separate SureSentry product line provides hardware-enforced one-way data diode security with FIPS 140-3 validated cryptography (NIST Cert #5003).

Sunhillo serves a concentrated mix of US federal and international customers: the FAA is its primary account (managing lifecycle of STARS, ECG, ATOP, RMLS, TDM to IP, and ATCBI/ASR11 programs), supplemented by US DoD (including US Army Alaska), NATO, Eurocontrol, NATS, and civil aviation authorities in 48 countries, plus enterprise customers such as Aireon and ResilienX. The company is ISO 9001:2015 and ISO 27001:2022 certified, holds FIPS 140-3 validation, and is recognized as a registered trademark holder (SureLine, SureSentry, Brigantine).

The business model combines one-time hardware capital sales with annual software licensing (Tier 1, Tier 2, and individual plug-in subscriptions), recurring hardware and software maintenance agreements, and professional services such as distributor training. Sunhillo sells directly to US government and large international accounts while routing regional international sales through a network of distributors covering Europe, Asia Pacific, and South America, with a 51-100 employee base supporting the operation.
