If you are a compliance lead or information security officer at a European cloud service provider, this playbook was built for you.
As a cloud provider operating in the EU, you face growing pressure to demonstrate compliance with the latest BSI C5:2026 standard, a mandatory benchmark for public sector contracts and enterprise customer procurement. Regulatory scrutiny is intensifying, with auditors demanding documented evidence of control implementation across infrastructure, identity, data protection, and incident response. Customers increasingly require formal attestation to C5:2026 as a condition of engagement, and failing to meet these expectations can delay sales cycles or disqualify your offering. The complexity of aligning internal processes with 165 controls across 17 domains, while mapping to ISO/IEC 27001, NIST SP 800-53, and GDPR, requires structured guidance and repeatable workflows.
Engaging a Big-4 consultancy to develop a C5:2026 implementation program typically costs between EUR 80,000 and EUR 250,000. Alternatively, assigning an internal team of 3 full-time compliance and security professionals would require 4 to 6 months of effort to build assessment tools, evidence procedures, and audit documentation from scratch. This playbook delivers the same structured methodology and comprehensive toolset for $395, enabling your team to execute the entire implementation independently and efficiently.
