**Buyer:** U.S. Office of Inspector General
**Posted:** October 14, 2026

**Identifier:** REQASR-26-00-041
**NAICS:** 541330, 561621, 541519
DHS OIG plans a sole-source, 12-month upgrade of physical security systems at its facilities through a modification to an existing Federal Supply Schedule order with Security Hunter, Inc.
- **Buyer:** Department of Homeland Security, Office of Inspector General (DHS OIG).
- **Procurement approach:** Sole-source modification to an existing FSS order with Security Hunter, Inc.; this is a planned procurement, not an award announcement.
- **Intrusion detection:** Convert all 29 systems from analog to digital, networked communications before analog phone service is discontinued in January 2027.
- **Physical access control:** Upgrade systems with modern controllers and PIV/CAC-compatible readers; requirements include 200-bit PIV-class encryption, PIV/CAC-only credentials, keypad-based two-factor authentication in sensitive areas, and OSDP reader communications.
- **Duration and rationale:** The modification has a 12-month period of performance. DHS OIG cites the incumbent’s system-specific expertise, transition schedule and security risks, and an estimated $100,000 cost to reproduce existing design work.
- **Scope limitations:** The notice does not provide equipment brands, part numbers, quantities for access-control components, or a contract value. The value range below is a rough estimate, not a published government estimate.
### Description
Department of Homeland Security, Office of Inspector General has a requirement to upgrade the Intrusion Detection System and Physical Access Control System. Security Hunter, Inc. currently provides DHS OIG with corrective maintenance, preventive maintenance, and related services for the affected physical-security systems under an existing competitively awarded FSS order.
