HSQ TECH, INC.

HSQ TECH, INC. specializes in the maintenance, repair, and modernization of critical industrial control systems, with deep expertise in Supervisory Control and Data Acquisition (SCADA) infrastructure. The company delivers end-to-end support for defense-related operational technology, including hardware upgrades, logic processor replacements, UPS battery and control system enhancements, and ruggedized computing solutions tailored for field-deployed environments. Their technical focus centers on ensuring the reliability and cybersecurity of mission-critical infrastructure, particularly in military installations, with demonstrated proficiency in server diagnostics, operator training, and spare parts procurement for legacy and modernized SCADA platforms. HSQ TECH distinguishes itself through its hands-on, field-responsive approach to sustaining complex electro-mechanical systems under stringent operational demands. The contractor maintains a consistent presence with the Department of Defense, providing sustained support for SCADA systems across military bases and utility infrastructure, including pump stations and building automation networks. Their work for the Department of the Interior reflects similar operational technology needs in federal facilities, suggesting a niche in maintaining mission-critical control systems across defense and public land management domains. HSQ TECH’s primary industry focus lies in Computer and Office Machine Repair and Maintenance (NAICS 811212), where they deliver physical and digital upkeep of industrial computing hardware, complemented by Computer Facilities Management Services (NAICS 541513) and Systems Design (NAICS 541512). This positions them as a specialized provider for legacy system sustainment rather than greenfield development, serving defense and federal infrastructure operators who require durable, field-tested solutions. As a small business structured as a 2L entity based in Hayward, California, HSQ TECH operates without federal certifications but leverages localized technical expertise to meet mission-specific requirements. Their geographic proximity to key DoD installations supports rapid response and on-site service delivery, reinforcing their role as a trusted sustainment partner for defense-critical control systems.
