The National Security Institute (NSI) was founded in 1985 by Stephen Burns and David Marston, two leading-edge security practitioners experienced with both government and corporate security environments. David and Steve were responsible for designing key programs that protected 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 and in training the average employee to keep sensitive information and proprietary data safe from outside and inside threats.
The world has changed a great deal since 1985 and 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 now widely used by America’s top corporations of all sizes and across all industries.
Born out of years of developing best practices that persuade the average employee to take security seriously, these continuous, enterprise-wide cybersecurity awareness programs are helping companies of all sizes and industries avoid costly security breaches.
NSI continues to evolve and develop solutions to support corporate and government security professionals everywhere.
With thousands of clients, NSI’s roots in protecting the nation’s defense technologies from corporate and nationstate espionage has evolved into enterprise-wide services that help all industries reduce the risk that cybercriminals will be able to exploit the average employee
