Quality with Confidence.

Thanks to our customer and process-oriented management system, we have been able to demonstrate compliance with the requirements of DIN EN ISO 9001 through certification since 1998. In 2023, our management system was re-audited and certified by the internationally leading certification body DQS/UL based on DIN EN ISO 9001:2015.

The redi-Group has been certified to ISO/IEC 27001:2022 since 2026. This certification confirms our compliance with internationally recognized information security requirements—for our central functions, affiliated redi locations, and services in quality consulting, quality engineering, quality assurance, and supplier management.

TISAX (Trusted Information Security Assessment Exchange) enables the cross-organizational recognition of information security assessments in the automotive industry.
The redi-Group underwent its first audit at its Munich location in 2017 in accordance with the VDA-ISA guidelines. The Leipzig and Langenfeld locations followed in November 2023. In 2026, the TISAX certification was successfully renewed for the headquarters in Langenfeld and the Munich location.

For all our sites, we have met the requirements for systematic and effective occupational safety based on “AMS-Arbeitsschutz mit System” and thus NLF / ILO-OSH 2001.
