Case Study: Swiss Payments Leader achieves PCI-DSS compliant AWS migration with Tarmac.IO

Swiss Payments Leader passes 3 PCI-DSS audits with Tarmac.IO

A Swiss payments leader needed to migrate to AWS without ever putting its compliance at risk, requiring a secure cloud foundation that would satisfy strict PCI-DSS requirements. The company engaged Tarmac as a partner to design and run this migration, seeking a technical peer rather than a typical vendor.

Tarmac designed and delivered the AWS migration using a secure, multi-account architecture defined in Terraform, with CI/CD pipelines to keep changes controlled and auditable. The solution passed three PCI-DSS audits across two products, giving the customer a secure, compliant, and repeatable cloud foundation. The vendor, Tarmac, was also praised for its collaborative way of working, which felt like a genuine conversation among peers.
