About the company

Written by GovTribe AI ·

Gregg Protection Services, LLC, a for-profit limited liability company and subsidiary of Centerra Group, LLC, provides security risk assessment, threat analysis training, and facilities management systems support to the Department of Energy National Nuclear Security Administration and the General Services Administration as a prime contractor exclusively, operating under GSA's Multiple Award Schedule and complementary Federal Supply Schedule contracts without set-aside restrictions.

Gregg Protection Services is classified as Other Than Small and headquartered in Herndon, Virginia. The company specializes in physical security assessments and specialized training delivery, centered on the Gregg Threat Assessment Program (G-TAP), a vulnerability assessment tool used by the Department of Energy, the Defense Threat Reduction Agency, and the Canadian Government to analyze risks at high-threat nuclear, biological, and radiological facilities. The firm's capability footprint reflects engineering-services and management-consulting backgrounds, with five awards classified under NAICS 541330 (Engineering Services) and two under NAICS 541611 (Administrative Management and General Management Consulting Services).

Customer concentration is stark: the Department of Energy National Nuclear Security Administration anchors 88% of combined potential value across four awards totaling $300.9 million, while GSA's Federal Acquisition Service holds the remaining four awards worth $38.9 million. The vendor operates on the Multiple Award Schedule with four task orders carrying the full $300.9 million in potential value. Gregg Protection Services' February 2026 GSA Multiple Award Schedule contract carries an $11 million ceiling and runs through February 2031, approved under three Special Item Numbers covering total solution support for facilities management systems, security system integration and design, and order-level materials. The labor portfolio spans nine positions ranging from Training Specialist I at $112.42 hourly (bachelor's degree, one year experience) to Security Specialist V at $199.83 hourly (master's degree, five years experience), with intermediate roles in program management, nuclear safety, and technology transfer. No security-cleared positions are offered. G-TAP training is priced at $5,175 per five-day session for 1-10 students, with additional students charged at $110.91 per day.

Activity has been episodic — one award in 2009, one in 2010, two each in 2012 and 2013, and a single award in 2026 — suggesting a consolidation around the recent GSA schedule renewal. Combined potential value across all awards stands at $339.7 million, though only $885 thousand has been obligated to date. The vendor holds no subcontractor awards in the source data and operates exclusively as a prime contractor.
