About Retarus

Retarus provides cloud platforms for secure, business-critical communication across email, fax, SMS, and EDI channels. Founded in 1992, the company serves mid-market and large enterprises that require reliable, high-performance digital communication infrastructure integrated with legacy ERP systems (SAP, Oracle, Dynamics 365) and modern standards (Peppol, EDIFACT, ANSI X12, e-invoicing). Operations span Germany, France, Spain, Romania, and the United States. The platform architecture relies on containerized infrastructure (Docker, Kubernetes) and emphasizes compliance (SOC 2, ISO/IEC 27001, HITRUST) and automation across supply-chain and business-process integration workflows.
