The Overseas Security Advisory Council (OSAC) is a public-private partnership between the U.S. Department of State’s Diplomatic Security Service (DSS) and security professionals from U.S. organizations operating abroad. Together, OSAC members share timely security information and maintain strong bonds for the protection of U.S. interests overseas. All OSAC products, events, and other resources are completely free and available to any U.S.-incorporated organization, their employees, as well as U.S. government, law enforcement, and military personnel.

The mission of OSAC is to promote security cooperation between the U.S. private sector and the U.S. Department of State by fostering a global network of security professionals who exchange timely information and security best practices to mitigate risks to U.S. interests worldwide. These bonds and the two-way flow of information help provide the broadest security perspective and the widest scope of support.
