A White Paper by Ross Foard, Foard Consulting LLC and Kelvin Brewer, Ping IdentityÂ
This white paper outlines a three-phase playbook for security consultants and agency leaders to baseline their current environments, align their metrics with the NIST SP 800-207 architecture and the CISA Zero Trust Maturity Model, and validate the real-time telemetry required to automate threat containment. The KPIs identified give an indication of the essential items in moving to a Zero Trust architecture and measurements organizations can use to gauge their progress.
