Rachel Cook

Rachel Cook serves as a Contract Specialist within the Contract Administration Services Division (70RCAS) of the Department of Homeland Security, where she plays a pivotal role in executing the agency’s mission to secure critical professional, scientific, and technical services that underpin national security operations. She manages the full lifecycle of acquisitions for high-priority contracts in systems engineering, cybersecurity, and research support, ensuring compliance with federal procurement regulations while advancing operational readiness and technological integrity. Her work directly supports the agency’s focus on sustaining mission-critical infrastructure through strategic sourcing of specialized services. Rachel cultivates collaborative relationships with a broad spectrum of contractors, primarily those offering administrative management consulting, data processing, and computing infrastructure solutions. She engages with both large-tier federal contractors and mid-sized firms possessing deep technical expertise in systems integration and cloud-based service delivery. Her procurement approach emphasizes performance-based contracting, clear statement of work development, and rigorous source selection criteria to ensure alignment with DHS mission outcomes. Rachel’s contracting patterns reflect a strong preference for full and open competition, with 100% of her awards issued without set-aside designations. While she does not routinely prioritize 8(a), HUBZone, or SDVOSB programs, her process remains transparent and inclusive, encouraging broad market participation through well-defined solicitation requirements and accessible pre-solicitation outreach. Her primary procurement focus lies in NAICS 541611 (Administrative Management and General Management Consulting Services), which accounts for half of her portfolio, followed by 541519 (Other Computer Related Services) and 518210 (Computing Infrastructure Providers). She specializes in acquiring technical advisory services, cybersecurity consulting, data center operations, and cloud migration support, demonstrating deep familiarity with federal IT modernization frameworks and mission-critical systems engineering requirements.
