ADJOINER CORPORATION

Adjoiner Corporation specializes in the design, installation, maintenance, and modernization of physical security infrastructure for federal defense facilities, with deep expertise in intrusion detection systems (IDS), access control platforms such as AMAG and GE Diamond, and closed-circuit television (CCTV) integration. The contractor delivers end-to-end security system sustainment, including sensor upgrades, hardware replacements, and system cutover operations, ensuring compliance with DoD physical security standards. Their technical proficiency spans legacy-to-modern platform migrations, card reader installations, and perimeter security system enhancements, demonstrating a strong command of integrated security architectures and field-deployed engineering support. Their ability to execute complex, time-sensitive upgrades across multiple installations—such as at Peterson Space Force Base—reflects operational agility and rigorous quality control under stringent government requirements. Adjoiner Corporation maintains a consistent relationship with the Department of Defense, delivering mission-critical security system services across multiple installations, primarily focused on base-wide infrastructure modernization and sustainment. Their work for the GSA includes engineering services under federal supply schedules, indicating a complementary capability in supporting broader federal procurement frameworks. The contractor’s primary industry focus is on Security Systems Services (NAICS 561621), where they operate as a specialized systems integrator for physical access and surveillance technologies. They are not a manufacturer or general IT services provider but rather a niche performer in defense-critical security infrastructure, positioning themselves as a trusted technical partner for DoD facilities requiring reliable, compliant, and up-to-date security system operations. Adjoiner Corporation is a small business structured as a 2L entity, headquartered in Buena Park, California. While currently holding no formal government certifications, their consistent award history with the Department of Defense underscores their proven ability to meet rigorous federal performance standards and deliver mission-essential security solutions under tight operational constraints.
