Disclaimer: I work at Red Hat. We believe that Open Source/Free Software is at the core of Digital Sovereignty. So we developed a #DigSov Readiness Assessment tool. Feel free to go through it at https://www.feedback.redhat.com/jfe/form/SV_1LGSam42lrM4Ddk Yes, this is me talking about and promoting my employer. But this tool means a lot to me, so accept my apologies if you think it's spammy.
Digital Sovereignty Readiness Assessment

This assessment helps evaluate your organization's digital sovereignty readiness.

@jwildeboer not spammy, mate, it's great you work there!
