The Mission of the FSNSIA is to establish a dynamic non-profit association of U.S. trained security professionals for the purpose of advocating for member welfare, enhancing US and allied diplomatic security, increasing member knowledge and professionalism, and promoting sound international security practices that support the rule of law and the best interests of the United States of America and allied Nations.

We are men and women who protect the mission of United States diplomacy abroad, or have previously protected diplomacy abroad. Our excellence in all facets of international security is exceeded only by our commitment to our profession and the rule of law.

We are in virtually every corner of the world and speak most of the world's languages. We seek to increase our professional knowledge through the identification and sharing of best practices, promote security that is both local and effective, and advocate for member welfare. We humbly recognize that there is no other organization in the world like us
