About the company
Joeun System Corp. Outsourcing Business Division is a Seoul-based, for-profit South Korean company specializing in providing English-speaking security guard services to the U.S. federal government. Registered in the System for Award Management since July 2007, the company has established itself as a critical security services provider for U.S. military and diplomatic installations throughout South Korea. The organization brings substantial relevant experience in comprehensive security personnel and guard force management, with particular expertise in staffing installation access control points, conducting anti-terrorism inspections, and maintaining security protocols in compliance with Department of Defense, Army, and United States Forces Korea regulations.
Joeun System Corp. has received federal contract awards totaling approximately $47.8 million across multiple delivery orders and one definitive contract since 2021, all without small business set-aside designations, indicating the company competes on an unrestricted basis. The company's recent contract work encompasses two primary service categories: English Required (ER) security guard services for U.S. Army installations across the Pacific Region, funded through various Army entities including the Pacific Region Installation Management Command, Army Intelligence and Security Command, and Army Pacific Command; and local guard services for the U.S. Mission in Korea, funded through the Department of State's Bureau of Diplomatic Security. Individual delivery orders issued under the company's primary Indefinite Delivery Contract with the Army have ranged from approximately $64,000 for initial phase-in periods to $12.6 million for annual option year periods, with awards made between November 2021 and April 2025. Additionally, in January 2026, the company was awarded a definitive contract valued at $11.7 million by the Bureau of Diplomatic Security for local guard services at the U.S. Embassy in South Korea, structured as a time and materials agreement covering the period from January 1, 2026 through January 31, 2031. All awards to date have been made as prime contractor positions with no identified subcontractors or set-aside designations.
Joeun System Corp. holds a single-award Indefinite Delivery Contract valued at $112.2 million with the U.S. Department of the Army Pacific Region for the provision of English-required security guard services at U.S. Army installations in South Korea. This IDV, awarded November 4, 2021, established a base period extending through November 3, 2024, with four additional one-year option periods, and operates without small business set-asides. Under this contract vehicle, the Department of the Army has issued eleven delivery orders totaling approximately $69.5 million between November 2021 and April 2025, with individual task order values ranging from approximately $64,000 to $12.6 million. These firm fixed-price delivery orders have been awarded by distributed Army entities including the Pacific Region Installation Management Command, Army Intelligence and Security Command, and Army Pacific Command, reflecting operational requirements across multiple installations. The contract structure provides the Army flexibility to adjust security staffing levels and resource allocation across installations through periodic task order issuances while maintaining continuity of operations through a single, established contractor relationship. The most recent delivery order under this IDV was issued April 4, 2025, valued at $10.5 million, covering the third option year period and extending the company's service provision through November 2025.
