OSAC is a partnership between the U.S. State Department and private-sector security community that enables the safe operations of U.S. organizations overseas through threat alerts, analysis, and peer network groups.

The OSAC Program Office is headquartered in Washington, DC and is overseen by a 34-member public-private Council. OSAC membership includes 5,400+ member organizations and 18,000+ individual members from corporate, non-profit, academic, and faith-based groups of every size, all with overseas operations and personnel who are exposed to ever-evolving security issues. 

The OSAC community collaborates in regional- and sector-specific committees to keep members informed, connected, and better equipped to manage complex security challenges around the world.
