+# SCS certification overview
+
+## Digital sovereignty drives SCS certification
+
+The SCS project takes a comprehensive perspective on digital sovereignty.
+Please read [Digital Sovereignty and SCS certification](digisov-and-cert)
+for more details.
+
+The basic level, control over data that at least allows to comply with the
+European GDPR regulation, is *not* certified by SCS; while the SCS software
+makes it easy to build (local) clouds that fulfill these, it depends on the
+operators of the infrastructure what compliance rules they fulfill.
+
+The SCS project however has defined certification levels for levels two,
+three and four in the sovereignty taxonomy.
+
+| Digital Sovereignty level         | SCS certification       |
+|-----------------------------------|-------------------------|
+| 1: Data Sov'ty / Legal compliance | (Refer to ENISA/Gaia-X) |
+| 2: Provider switching / Tech Compatiiblity | SCS-compatible |
+| 3: Ability to shape technology    | SCS-open                |
+| 4: Transparency & SKills for Operations    | SCS-sovereign  |
+
+As of September 2024, the *SCS-compatible* certification level is defined
+and used; the details for the higher levels are still being worked on.
+
+## Certification process
+
+To get certified, the infrastructure needs to fulfill the criteria.
+As far as possible, these are implemented as automated tests that run
+continuously (daily) to assure continuous compliance. The results are
+made transparent via the the [Certified Clouds overview](overview) page.
+
+To get officially certified with the right to use the SCS brand and getting
+listed on this page requires to work with the Forum SCS-Standards at the
+[OSB Alliance](https://osb-alliance.com/) which takes over this aspect
+from the [SCS project](https://scs.community/). It requires membership
+or certification fees to cover the efforts of standardization and
+certification.
+
+The process is described in more details on the
+[Getting SCS-compatible certification (for Operators)](getting-scs-compatible-certified)
+page. An example with technical testing and adjustments is on the
+[Testing and Adjustment example](test-and-adapt-example) page.
