ISO 27001:2022 vs C5 (Germany)

What is the difference between ISO 27001:2022 and C5 (Germany)?

ISO 27001:2022 is an information security framework applying in International, with 123 controls across 11 domains. C5 (Germany) is a compliance framework applying in Germany, with 121 controls across 17 domains. They govern different subjects, so the overlap is limited to the governance requirements they share. The mapping below shows where that is.
