Open CDC, a 27-country map for building cyber defence centers
An open-source framework for designing, operating, and maturing security operations and cyber defence centers across the European Union.
Field notes
The framework is organized around six operational functions and several entry routes, including a first-90-days guide, implementation tiers, workshops, and a maturity self-assessment. Its supporting material extends into operating models, roles, detection-as-code, threat intelligence, templates, metrics, and platform-specific playbooks for Windows 11, macOS, and RHEL. A particularly broad element is the national-annex section, which lists every EU member state, alongside crosswalks to NIST CSF 2.0 and CIS Controls.
