Product/service quality and data security are a matter of trust

T-Systems operates data networks and processes data for its customers worldwide in its own data centers, giving absolute top priority to data protection and data security. The ICT provider therefore has its services audited regularly by independent institutes. Furthermore, the provider has its compliance with global standards accredited, for instance, through ISO certifications.
Sustainable corporate management is the basis for the wide range of certificates awarded. T-Systems subsidiaries thus currently meet standards ranging from quality management, information security management and service management requirements to environmental management and occupational safety and health care.

Top marks for high service standards

T-Systems achieves excellent scores in surveys, for example, on customer satisfaction. In the current TRI*M study by TSN Infratest, the Telekom subsidiary is once again among the top 10 percent of European ICT service providers.

DEKRA Trusted Cloud vCloud OTC
With the TCDP 1.0 certificate, T-Systems is the first IT Service Provider to comply with a legally compliant data protection certification for defined cloud services.
A certificate based on the Trusted Cloud Data Protection Profile (TCDP) makes it much easier for companies to fulfill the control obligations for commissioned data processing. The TCDP formulates objective criteria that can be used to compare the security level of different cloud services. These criteria are grouped into clear protection classes. By selecting a service with the TCDP certificate, the control obligations are fulfilled according to the German Federal Data Protection Act. TCDP is based on ISO 27001 and ISO 27018.
Advantages for our customers:
  • Cost savings because an own assessment pursuant to § 11 paragraph 2 of the German Data Protection Act (BDSG) is no longer required
  • The level of data protection of the service can be assessed transparently
  • The possibility of observing the data protection regulations against their own customers.
CSA STAR
The CSA STAR Certification is an independent third party assessment of the security of a cloud service provider. The technology-neutral certification leverages the requirements of the ISO/IEC 27001 management system standard together with the CSA Cloud Controls Matrix, a specified set of criteria that measures the capability levels of the cloud service.
