Our Story

Steel Root is the first cybersecurity firm to provide end-to-end services for the U.S. Defense Industrial Base.

Steel Root is a national leader in helping U.S. government and defense contractors meet cybersecurity and compliance requirements under DFARS, FAR, and export controls. Now in its fifth year, Steel Root was founded to serve growing businesses through enterprise-class security consulting and managed services.

The company launched in 2016 as a security-focused IT services provider, serving companies in the greater Boston area. Following the publication of NIST SP 800-171, the company began to specialize in publicly-vetted cybersecurity frameworks and national standards. Years of experience implementing and operationalizing security best practices has established Steel Root as a premier cybersecurity firm for companies across the United States.
