Best in class for business-critical processes.

We operate all Retarus platforms in our own data centers and in protected areas of certified co-locations with our own hardware and with multi-tenant software we’ve developed ourselves. Our entire infrastructure is designed to offer you the performance level you need for your communication processes—at all times. Regardless of whether you send 10,000 messages today and 10 million tomorrow.

Compliance made easy. Right up to individual supplier audits.

The strict implementation of compliance requirements is essential, particularly in heavily regulated sectors such as finance and healthcare. In addition to compliance with standards such as ISAE 3402 or SOC 2, Retarus is certified for numerous country-specific data protection standards such as ENS or HIPAA and complies with industry-specific standards such as TISAX and PCI DSS. Everything is closely monitored by our internal security framework and external auditors. You can experience this yourself at any time as part of your own audit. We will be happy to provide you with information about our data centers and all of its relevant processes.

Real support. And contractually agreed service levels.

No impersonal call center. Instead, Retarus has experts with solid messaging know-how who are there for you 24 hours a day, 365 days a year. Worldwide and in your language. We will work with you from the start to identify the service level you need. We can also provide you with your own service manager. We support you during the implementation of the service and help you further develop your communication and business processes, allowing you to adapt to new market situations. You can rely on us. We stand by your side throughout each phase of our joint project.

Enterprise at its best. Service portal, continued developments and updates.

You can easily monitor and manage all of your Retarus services in one unified web-based service portal. Including detailed real-time reporting and monitoring. This allows you to precisely track every email as it travels through our infrastructure. The transparent display of all service features gives you maximum control over your communication processes. What’s more, our reporting API provides you with raw data to be integrated directly into your applications for further processing. For example, in SOC/SIEM tools or AI applications.
Maintenance windows? We decided to close them. All software components on Retarus’ platforms are continuously developed and updated on an almost daily basis without any downtimes. Retarus’ services are always available without restrictions, even during an update.
