The Challenge

As one of Europe's largest telecommunications providers, Deutsche Telekom operates a vast and complex infrastructure spanning traditional data centers, private clouds, and public cloud environments. With over 200,000 employees and critical telecommunications infrastructure serving millions of customers, maintaining security and compliance across this hybrid environment presented significant challenges.

The security team needed to ensure compliance with stringent European regulations including GDPR, while also meeting telecommunications-specific security requirements and maintaining ISO 27001 certification across their operations.

  • Managing security across a complex hybrid infrastructure spanning legacy systems and modern cloud services
  • Maintaining compliance with multiple regulatory frameworks including GDPR, ISO 27001, and telecommunications-specific requirements
  • Providing unified visibility across 10,000+ assets distributed across data centers and cloud environments
  • Reducing manual effort in security operations while scaling to meet growing infrastructure demands
  • Coordinating security policies across multiple teams and business units
The speed and accuracy of Mondoo's platform, combined with its deep insights into IT architecture, enables customers to quickly remediate issues and significantly reduce CVEs and policy violations.
