Tamara Norrenberns

Tamara J. Norrenberns serves as a key procurement professional within the Telecommunications Division (HC1013) of the Defense Information Systems Agency, where she supports the acquisition of mission-critical telecommunications and network infrastructure solutions. Her work directly enables DISA’s mandate to secure, sustain, and modernize the Department of Defense’s global communications architecture. She routinely manages complex acquisitions for satellite communications, secure network services, and custom IT systems, ensuring alignment with DoD cybersecurity standards and interoperability requirements across joint and coalition forces. Her contracting portfolio emphasizes resilient, high-capacity connectivity solutions that support expeditionary and enterprise-level operations. Norrenberns maintains longstanding relationships with leading telecommunications and systems integration contractors, including AT&T Technical Services Company, Inc., AOC CONNECT LLC, and Norfolk Fiber, LLC. These partnerships center on the delivery of secure virtual private networks, fiber-optic infrastructure, and satellite-based communication platforms. Her procurement approach favors established vendors with proven track records in defense-grade telecom systems, while also engaging specialized firms in wireless equipment manufacturing and custom software development to meet evolving operational needs. Her contracting activity reflects a strong preference for open competition, with 95.5% of awards issued without set-aside designations. Only 4.5% of awards are structured as total small business set-asides under FAR 19.5, indicating a primary focus on technical capability and mission readiness over socioeconomic preferences. While small business participation is not a dominant driver, she adheres to all applicable regulations and occasionally leverages small business capabilities when technical requirements align with their specialized expertise. Norrenberns’ procurement focus is concentrated in NAICS 517410 (Satellite Telecommunications), 541519 (Other Computer Related Services), and 541512 (Computer Systems Design Services). She consistently acquires secure satellite bandwidth, network architecture design, and mission-specific software integration services, demonstrating deep expertise in military-grade telecommunications systems, encrypted data transport, and next-generation networking technologies essential to DoD’s digital transformation.
