About Us

G2’s commercial practice has 13 year history in performing cybersecurity assessments and assisting supporting national security initiatives throughout the Federal Government. Through our strong cybersecurity expertise and experiences assisting NIST in other initiatives such as the development and maintenance of Security Content Automation Protocol (SCAP), G2 was selected by NIST as the primary contractor in the development of the Cybersecurity Framework. G2 assisted NIST in reviewing information received through the Request For Information (RFI) and Request for Comment (RFC) process. We also assisted in the execution and facilitation of the workshops that led to the development of the Cybersecurity Framework.

G2 remains engaged with NIST as the primary contract assisting in developing an ecosystem to sustain and nourish future development of the Cybersecurity Framework.
