About the National Security Institute.

The National Security Institute (NSI) was founded in 1985 by Stephen S. Burns and David A. Marston, two leading-edge security practitioners whose combined experience includes over thirty-five years in government and corporate security environments. David and Steve were responsible for designing key programs for protecting some of the nation’s most sensitive technology and business secrets.

The National Security Institute quickly became the leading organization dedicated to assisting cleared defense contractors in understanding the threats to national security.

The world has changed a great deal since 1985. So has the National Security Institute.

While NSI maintains its respected flagship information services for government and defense contractor security executives, our employee security awareness programs are also widely used by America’s top corporations to educate employees to the risks of critical information loss from hackers, spies and data thieves.

These continuous, enterprise-wide programs are helping companies avoid costly security breaches by creating end-user awareness and arming employees with practical, fail-safe solutions for protecting vital corporate information.
