FORMAT AND DELIVERY
The CPG assessment is offered through the Cyber Security Evaluation Tool (CSET®). CSET® is a Department of Homeland
Security (DHS) product that assists organizations in protecting their key national cyber assets, offering more than 60
different cybersecurity assessments. This tool is a downloadable, stand-alone desktop application that provides users
with a systematic and repeatable approach for assessing the security posture of their cyber systems and networks.
Within CSET®, the 38-question CPG assessment can be done through self-assessment or facilitated with a CISA partner.
The CPGs will be regularly updated, with a targeted revision cycle of every six to twelve months. As such, feedback is
appreciated and can be submitted at https://www.github.com/cisa/cyber-performance-goals.

Note the github link. I don't think https://www.github.com/cisa is the droid we are looking for.
