Mark Landon

Mark Landon serves as a Contract Specialist within the Contracting and Procurement office of the Transportation Security Administration under the Department of Homeland Security. He plays a pivotal role in executing mission-critical acquisitions that support national transportation security, specializing in the procurement of advanced detection systems, cybersecurity services, and operational technology solutions. His portfolio includes complex contracts for explosive detection equipment, irradiation systems, and GPS-enabled rail monitoring technologies, ensuring alignment with TSA’s strategic imperatives for aviation and transit security. Landon applies full lifecycle contracting expertise—from market research and solicitation development to award and contract administration—to deliver timely, compliant, and high-value solutions that meet evolving threat landscapes. Landon collaborates with a diverse range of vendors, including specialized technology integrators, IT service providers, and engineering consultants. While no single contractor dominates his portfolio, he consistently engages firms with proven capabilities in security system deployment, data infrastructure, and mission-critical software development. His working relationships emphasize performance-based contracting, rigorous technical evaluation, and post-award oversight to ensure vendor accountability and system readiness. Landon demonstrates a strong commitment to small business participation, with approximately 30.8% of his acquisitions structured as total small business set-asides under FAR 19.5. He actively leverages socioeconomic programs to expand vendor diversity, prioritizing small businesses with expertise in technical services and government compliance. Though no specific set-aside categories like 8(a) or HUBZone are dominant, his contracting patterns reflect a deliberate effort to foster equitable access and build a resilient small business supplier base. His primary procurement focus centers on NAICS 541611 (management consulting), 541519 (other computer-related services), and 541810 (advertising agencies), reflecting a need for strategic advisory services, IT modernization, and mission communications. He routinely procures cloud infrastructure, data processing services, and specialized software solutions, demonstrating deep technical fluency in cybersecurity, systems integration, and digital transformation within high-security environments.
