Hello all - In the past few weeks since version 2 of the CISA Zero Trust Maturity Model (ZTMM) was released, We've all had numerous conversations about how organizations can and should use it. Inspired by these conversations, and in an effort to contribute to the community, I've created an interactive, easily manipulated spreadsheet version of the CISA Zero Trust Maturity Model, and made it freely available here https://numberlinesecurity.com/ztmm/
On that web page, I provide an overview of the CISA ZTMM, and an explanation of the interactive spreadsheet. You'll also find a link to Google Sheets and Microsoft Excel versions.
This spreadsheet contains:
-
The full set of CISA functions and maturity levels, in editable text form
-
An interactive worksheet, where you can select your organization's maturity level
-
A results worksheet, where your selections are automatically rendered
I welcome your comments and suggestions for improvements, and I hope people find this valuable.
regards
Jason
