Security Information Systems, LLC

Security Information Systems, LLC, a for-profit entity based in Orlando, Florida and operating as Security Information Systems Inc., delivers alarm system hardware, monitoring software, automation services, and technical support to federal agencies primarily as a prime contractor (87% of recent awards) under full-and-open competition with no recurring set-aside designations. The vendor operates as a subsidiary of Security Information Systems, the parent entity.

Security Information Systems' capability footprint centers on physical security alarm infrastructure — intrusion detection, fire alarm reporting, and alarm monitoring center operations — with a secondary stream of systems engineering and technical integration work. Recent prime work includes a $793 thousand DHS Office of Procurement Operations definitive contract (2022–2023) for maintenance, technical support, and training on alarm monitoring systems processing intrusion and fire detection signals at DHS Mega Centers in Orlando; a $371 thousand Air Force Space Command purchase order (2024–2029) for Fire Alarm Reporting System (FARS) alarm center support plan software subscription maintenance; a $334.6 thousand U.S. Secret Service definitive contract (2024–2029) for Mystique alarm system upgrade and support at Sand Lake, Florida; and ongoing smaller purchase orders from DHS Headquarters Division and Air Force Space Command for DSIC SIS alarm systems and Vandenberg Space Force Base alarm automation software services. The source traces alarm automation work back to at least 1998.

Customer concentration is diffuse but anchored by Department of Homeland Security agencies. The top five customers by award count account for 47% of awards and represent only $2.6 million in combined potential value, while the top five by potential value (86% of combined potential dollars) are led by DHS Office of Procurement Operations ($4.2 million), DHS Chief Procurement Officer ($3.6 million), and DHS National Protection and Programs Directorate ($2.6 million). Department of State Bureau of Diplomatic Security places the most awards by count (16), while Air Force Space Command (13 awards) and Department of Navy Installations Command (10 awards) round out the distribution. The disparity between volume and dollars signals many small task orders alongside larger DHS contracts.

The vendor operates under three principal IDCs: an Indefinite Delivery Contract (N3943021D2230) with 10 task orders, an Indefinite Delivery Contract (HSCEGI07D00003) with 6 task orders ($2.1 million combined potential value), and an Indefinite Delivery Contract (N6600118D0082) with 4 task orders. Primary NAICS classification is 541381 (Security Systems Services except Locksmiths), covering 76 of 115 awards, with a secondary engineering services and software publishing presence. Activity has been steady at 6–7 awards annually through 2024, with only one award in 2025 and one in 2026 — a potential signal of contract cycle consolidation rather than growth. Only $546 thousand in combined potential value faces recompete inside the next twenty-four months.

Security Information Systems subcontracts extensively under Serco Inc. on Navy and DHS public safety systems (PSS) and antiterrorism/force protection (AT/FP) sustainment work, with 13 of 15 sub-awards routed through Serco. One notable sub-award with M.C. Dean, Inc. (April 2024) involves systems engineering and management support for the Commander, Navy Region Naval District Washington Local Alarm Monitoring Automation System (LAMAS) and integrated alarm dispatch to the Washington Navy Yard and subordinate Naval Security Activity sites in Maryland and Virginia. Sub work is concentrated in Navy and DHS global sustainment streams rather than tactical development.
