NSI helps you cost-effectively implement government security directives
and comply with NISPOM requirements.

Established in 1985, The National Security Institute (NSI) provides a variety of professional information and security awareness services to defense contractor and U.S. government security practitioners.

NSI's core business is helping clients interpret and implement government security directives and establish sound security strategies that effectively safeguard classified and proprietary information.


We help government and defense contractor security professionals in two ways:

IMPACT Security Conference
Held annually in the Washington, D.C. area, NSI’s IMPACT conference has been educating security managers for a quarter of a century on the latest national security threats and how to defend against them.

Employee Security Connection
This unique security awareness program is designed to educate employees in both government and the defense industry on their responsibilities for protecting classified and sensitive national security information. EMPLOYEE SECURITY CONNECTION fulfills a major NISPOM security awareness requirement.
