Building a Foundation of Integrity

Headquartered in Alexandria, Virginia, Guardtime Federal delivers data integrity for defense and aerospace that’s beyond strong—it’s mathematically verifiable.

Since 2014, Guardtime Federal has worked to support the cybersecurity-related requirements of the Department of Defense and other U.S. government departments as well as the intelligence community and industries that support these government organizations.

Guardtime Federal licenses the KSI technology from a foreign parent, Guardtime SA, to adopt for U.S. Government customers. Guardtime Federal modifies the licensed software to ensure compliance with U.S. Government security standards and Prime Contractor requirements. This process leverages U.S. third party verification and testing to ensure customers’ security and performance needs are assured. To mitigate any potential for inappropriate foreign influence, Guardtime Federal operates independently, consistent with an approved DOD Special Security Agreement with the Defense Counterintelligence and Security Agency.

Integrity is more than what we provide with our products, it guides how we behave and communicate with our customers and each other.

Service

Service always comes before self. We go the step beyond and embrace the hard things in order to achieve customers' goals.
