Research and innovation

Since 1992, all core systems for Retarus cloud services have been developed in-house. As early as 1994 – only two years after the company was founded – Retarus was essentially the first company to offer Europe-wide managed services for email security. Ever since, we have expanded and further developed our product portfolio for fax, email, SMS, and business integration.

Our research division is continuously developing innovative ideas and solutions and we protect this intellectual property for both our customers as well as our company.
