This section takes you through the Assessment phase, which contains the first steps in any Zero Trust journey. First, we introduce you to why and how to perform a Zero Trust Readiness assessment, through a presentation and an interactive exercise. Then, we introduce ZTMM+, our enhanced and extended version of the CISA Zero Trust Maturity Model. We explain why we created ZTMM+, perform an exercise where you begin using it, and conclude with guidance on how to use the ZTMM+ tools and assets to apply it to your enterprise for real.
