As data protection regulations tighten and cloud adoption accelerates across Europe’s most regulated industries, trust and compliance are no longer differentiators; they are prerequisites. Today, we are proud to announce that Skyhigh Security has achieved BSI C5 (Cloud Computing Compliance Criteria Catalogue) certification, issued by Germany’s Federal Office for Information Security (Bundesamt für Sicherheit in der Informationstechnik- BSI).

This milestone brings the full Skyhigh Security Service Edge (SSE) Portfolio to the German market under one of Europe’s most rigorous and respected cloud security frameworks, reinforcing our commitment to protecting the most sensitive data in the world’s most demanding regulatory environments.

What is BSI C5?

The BSI Cloud Computing Compliance Criteria Catalogue (C5) is a government-backed security attestation scheme developed by Germany’s Federal Office for Information Security. Designed specifically for cloud service providers, C5 establishes a comprehensive set of security criteria covering:

• Organization, policies, and security management
• Human resources security and physical access controls
• Identity and access management
• Cryptography and data protection
• Availability, recovery, and business continuity
• Incident management and forensic readiness
• Compliance and data sovereignty

C5 is particularly critical for organizations operating in healthcare (§ 75b SGB V), financial services (BAIT/VAIT), and German public sector IT (BSI IT-Grundschutz), where cloud providers must demonstrate independently attested, audited security controls before they can be trusted with sensitive workloads.

What This Means for Skyhigh Security Customers in Germany

With BSI C5 certification, Skyhigh Security becomes a certified cloud security partner for organizations in Germany’s most regulated and sensitive sectors. Our full SSE Portfolio; including Skyhigh Secure Web Gateway (SWG), Cloud Access Security Broker (CASB), Zero Trust Network Access (ZTNA), and Advanced Data Loss Prevention (DLP), is now available under the C5 framework.

This means German enterprises and public sector agencies can now:

• Deploy the Skyhigh SSE Portfolio with the confidence of BSI C5 attested security controls
• Meet procurement and compliance requirements for cloud services in regulated public and private sector environments
• Leverage a unified, data-first cloud security platform proven in the German regulatory context
• Protect highly sensitive data, including health records, financial data, and government information, with independently audited controls

“We’re bringing the full stack of the Skyhigh SSE Portfolio to the German market with the BSI C5 framework. Skyhigh is continuing to invest in growth opportunities in Germany to protect the highly sensitive data often required for sensitive sectors like healthcare, finance, and German public sector IT.” Peter Godden, Vice President, Skyhigh Security EMEA

Why BSI C5 Matters for Regulated Industries

Germany has some of Europe’s strictest requirements for cloud service providers operating in critical and sensitive sectors. BSI C5 is recognized by German federal and state authorities, financial regulators (BaFin), and healthcare bodies as the benchmark for cloud security assurance. For procurement teams, security officers, and compliance leads, a C5 attestation significantly reduces the due diligence burden when onboarding cloud security vendors.

With data protection and digital sovereignty concerns growing across the EU, driven by GDPR enforcement, the NIS2 Directive, and sector-specific regulations, the ability to demonstrate BSI C5 compliance is increasingly a commercial and regulatory necessity, not just a competitive advantage.

Part of a Growing Global Compliance Portfolio

The BSI C5 certification joins a comprehensive and growing list of compliance certifications and frameworks that Skyhigh Security maintains globally, including:

• FedRAMP High — U.S. Federal Government (CASB, SWG, DLP)
• ISO/IEC 27001 — International information security management
• SOC 2 Type II — AICPA Trust Services Criteria
• IRAP PROTECTED — Australian Government (renewed 2026)
• GDPR — European Union data protection
• DORA — EU financial sector digital operational resilience
• DPDPA — India data protection compliance
• CSA STAR Level 1 — Cloud Security Alliance
