Working Together to Protect U.S. Interests Overseas

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


OSAC's public representatives work directly with security professionals from U.S. private-sector organizations that have employees, operations, or other interests outside the United States. We do not support private U.S. citizen travelers or individuals of any other nationality who are not affiliated with a U.S. private-sector organization.



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. 

OSAC's Executive Director is Ellen Tannor.



OSAC's Mission and Values:

As threats continually arise and evolve across the world, U.S. organizations require a trusted network to maintain peak awareness and readiness to respond. OSAC is dedicated to maintaining strong bonds and collaboration between public and private security professionals for the broadest perspective and widest scope of support.

We strive to continually learn from one another and reinforce each other’s safety. Our peer networking groups focus in on specific industries and regions and are co-led by representatives from both the U.S. Department of State and private-sector organizations, operating abroad. This two-way partnership is key to staying informed and secure. OSAC members can reach out to our analysts directly with requests for analysis and benchmarking around specific issues of concern. Regional security officers can get better informed by those working within the facilities we’re committed to protect. And all OSAC members can keep in touch with each other at all times through dedicated communications channels.

OSAC is accessible. We have over 150 Country Chapters in nearly every country in the world and all OSAC events and resources are free of charge, ensuring corporate, nonprofit, academic, and faith-based organizations of every size can get involved.

The core mission of this unique global security community is to provide critical support during times of crisis and an invaluable ongoing exchange of information and best practices that will empower members to stay informed, connected, and better able to manage and mitigate risk.
