CSA CCSK
Cloud Security Alliance Certificate of Cloud Security Knowledge

The CCSK from the Cloud Security Alliance is one of the most widespread vendor-neutral cloud security certifications worldwide. It is based on three core sources: the CSA Security Guidance v4, the ENISA Cloud Computing Risk Assessment, and the CSA Cloud Controls Matrix (CCM). The exam is fully online and open-book — this lowers the entry barrier but also means less practical proof than e.g. CCSP. No professional experience required, no expiration date. Good as an entry point into cloud security and as preparation for the CCSP, but not a strong career building block on its own.

Amazon Web Services Certified Security - Specialty

The AWS Security Specialty is AWS's most demanding security certification and requires solid practical experience with AWS workloads. It covers a broad spectrum: from IAM and data encryption to incident response, logging, and compliance. The practical relevance is high; pure textbook candidates typically fail. The certification has high market value potential, as it is regarded as proof of quality for security architects in cloud environments. Important: Version SCS-C02 was superseded in December 2025; SCS-C03 is now current.
