Scope & Shared Responsibility ​

Apeiro is a reference architecture and open-source construction kit. Platform operators and solution providers assemble, configure, and operate the components. Understanding what Apeiro provides and what operators must own is essential for correctly interpreting the security documentation.

What Apeiro Provides ​

  • A reference architecture for sovereign cloud-edge environments
  • A set of open-source building blocks with defined integration points
  • A vendor-neutral framework that allows to combine security components

Apeiro is not:

  • A managed security service
  • A certified ICT product (Apeiro is not itself a certified product; individual components may have their own certification status)
  • A compliance framework or certification body
  • A substitute for an organization's security policy, incident response process, or regulatory compliance program

Shared Responsibility ​

The following table clarifies what Apeiro provides architecturally versus what remains the operator's responsibility.

What Apeiro Does Not Define ​

The following are examples of things explicitly not provided by Apeiro and must be addressed by the operating organization. This list is illustrative, not exhaustive:

  • DDoS mitigation mechanisms or uptime guarantees
  • Specific Recovery Time Objectives (RTOs) or Recovery Point Objectives (RPOs)
  • SOC metrics such as Mean Time to Detect (MTTD) or Mean Time to Respond (MTTR)
  • Incident response playbooks or SLAs
  • Data classification schemes or data retention policies
  • Formal threat-model review processes or review frequencies
  • Enterprise risk management processes
  • Patch SLAs or vulnerability remediation commitments
  • Certification strategy or regulatory compliance programs
  • DDoS preparedness exercises, disaster recovery testing, or failover drill schedules

Regulatory Context ​

Apeiro's open-standards foundation and software supply chain transparency are designed to support organizations in meeting evolving regulatory requirements, including the EU Cyber Resilience Act, national cybersecurity frameworks, and sector-specific regulations. Regulatory compliance, however, is always the responsibility of the deploying organization. Apeiro generates evidence and provides architectural building blocks; compliance decisions and certification activities remain with the operator.
