Does your organization have a cybersecurity policy? It should live in Keystone.

Keystone is a web application developed by Complex Systems Group to help teams to centralize and maintain safety, cybersecurity, and other policy documentation.

Keystone also intends to help teams to centralize and maintain intent specifications, the output of the STPA safety analysis process, and other safety analysis techniques like fault-tree analysis (FTA).

Keystone Desktop is a fully-local version of the webapp wrapped in an Electron application and available for Windows, Mac and Linux. It is best suited for solo users and small teams, and is currently in private alpha.

Keystone Cloud is a planned hosted software-as-a-service (SaaS) version of Keystone for larger and more-distributed teams.
