What Systems Engineering does

Systems Engineering, Inc. (SEI), doing business as SEI Secure, is a privately held, SBA Certified Small Disadvantaged Business founded in 1987 and headquartered in Dulles, Virginia. The company designs, engineers, integrates, installs, and maintains physical security systems — including electronic access control, intrusion detection, closed-circuit television, smart card credentialing, and Physical Security Information Management (PSIM) — for U.S. federal government customers across the Department of Defense (MDA, Army Operational Test Command), Department of Homeland Security (USCIS), Department of the Interior (BLM, NIFC, USGS, BOEM), Treasury, Agriculture, SSA, DOJ, and the National Transportation Safety Board. SEI also serves as an official distributor for AMAG, Hirsch/Identiv, Gallagher, Avigilon, Milestone, Salient, Hanwha, Advancis WinGuard, AmberBox, EAGL, O.W.L. GroundAware, Summit Worx, and Minder, integrating these third-party products with proprietary methodologies (Mission Driven System Integration / MDSI and Modular Building Concept / MBC) plus an Integrated Situational Management (ISM) overlay that unifies physical and non-physical systems into a common operating picture.

SEI generates revenue through two principal streams: (1) professional services for security system integration projects awarded through federal contracts, and (2) hardware resale of access control, video management, and specialized detection products. Go-to-market is almost exclusively enterprise field sales to federal agencies, conducted through GSA Multiple Award Schedule Contract #47QSWA18D0023, NASPO ValuePoint Master Agreement #3407, and direct contract awards. The company's competitive positioning is built on dense federal certifications (HSPD-12 Provider, FIPS 201/FICAM, UL 2050, CSEIP) and 35+ years of past performance.

Beyond traditional physical security, SEI has built an AI/ML research line — Military Evasive Route Planner, Civilian Search and Rescue Tool, AI Preparation of the Battlespace, Tactical Real-time Decision Support, AI Military Force Composition, Tactical PSIM for austere environments, and Virtual Combat Training — developed under SBIR awards and in collaboration with the Air Force Research Laboratory/AFWERX and the Office of Naval Research.

Recent moves6 records

Expansion highlights5 records

Direct peers

• Genetec: Developer of Security Center, a unified security platform (PSIM-like) combining video surveillance, access control, and intrusion management; a competitor and complement to SEI's PSIM integration services, frequently deployed in federal and critical-infrastructure environments.
• Convergint Technologies: One of the largest independent security systems integrators in North America, providing design, installation, and integration of access control, video surveillance, intrusion detection, and PSIM for federal, commercial, and enterprise customers — directly overlapping SEI's core integration services across the same product ecosystem (e.g., AMAG, Avigilon, Milestone).
• Salient Systems: Open-architecture video management systems (CompleteView VMS) provider integrated by SEI; comparable because Salient sells a VMS platform that competes with the broader VMS ecosystem SEI integrates for federal end-customers.
• Milestone Systems: World-leading open-platform IP video management software (XProtect) provider — one of SEI's go-to VMS integration partners — and an adjacent comparable as a software-led security platform vendor frequently deployed alongside PSIM in federal accounts.
• Protection Strategies Inc. (PSI): Small-business federal integrator specializing in physical security, electronic security systems, and SCIF construction for DoD and intelligence community — comparable size and customer overlap with SEI on federal access control, intrusion detection, and PSIM integration contracts.

Broad incumbents

• Kratos Defense & Security Solutions: Federal-focused defense and security solutions provider with significant federal electronic security, C5ISR, and cyber work; overlaps with SEI's DoD agency customers (e.g., MDA, Navy, Air Force) and competes for similar federal security integration contracts.
• Allied Universal (incl. ADT Commercial / G4S): Large, broad security services and systems integration provider serving federal government and commercial accounts with electronic security, manned guarding, and integrated solutions — competes for the same federal electronic security system integration opportunities as SEI, but at much greater scale and as an incumbent.
• Leidos: Large federal systems integrator with significant electronic security, base operations, and physical security work for DoD and civilian agencies; competes with SEI for federal security integration task orders and can absorb smaller integrators as subcontractors.
• Johnson Controls (Security Products / Tyco/Exacq): Global building technologies provider offering integrated electronic security (access control, video, intrusion) as part of a broader building management portfolio; competes for large federal and enterprise security integration programs that overlap with SEI's access control and CCTV work.

Others

• AMAG Technology (now part of ASSA ABLOY / Allied Universal): Manufacturer of Symmetry Access Control, a core product in SEI's federal portfolio; an OEM partner rather than direct competitor, but illustrates the same federal PIV/HSPD-12-compliant access control market SEI serves.
