VERIFIED SECURITY

Digital sovereignty and security

Outsourcing infrastructure means giving up control? With colocation in FRA7, your systems, data, and software stack remain in your hands. What firstcolo takes over is operating the physical base infrastructure.

  • Data location Germany: FRA7 is operated in the EU by firstcolo, a German operator with no US parent company. This eliminates CLOUD Act scenarios; European law applies.
  • Planned certification framework: ISO/IEC 27001, ISO 9001, ISO 14001, ISO 45001, ISO 50001, EN 50600, and the requirements for critical infrastructures (KRITIS) are planned for operations—a reliable framework for security, quality, energy efficiency, and resilience.
  • Physical security: Controlled access systems, 24/7 monitoring, and DDoS protection at the infrastructure level form the operational protection layer—before traffic and access reach your systems.
