Rest assured with cloud messaging that fulfills control standards including SOC 1, SOC 2, PCI DSS, and ENS.

The Retarus Messaging Platform ensures secure business communication via fax, email and SMS. When combined with OCR and Intelligent Document Processing, it unlocks an entire world of process digitization and automation. In terms of communications, Retarus provides flexibility today which business will need tomorrow.

The First Cloud Messaging Platform for Email, Fax, and SMS That Fulfills the Greatest Demands.

Want to consolidate and modernize your IT? Ensure that your employees and systems can communicate quickly and reliably via transactional fax, email, and SMS? Increase productivity and efficiency through automation? Reduce overall costs? Retarus offers everything you need:

Maximum performance and security.

The Retarus Messaging Platform is based on an intelligent cloud infrastructure with data centers distributed all over the world. Connected via dedicated lines, international Tier 1 carriers, and local providers. Equipped with carrier-grade equipment and a future-proof, multi-tenant architecture that allows us to further develop and update software components on our platforms without downtimes or maintenance windows. The result: maximum availability, performance, and security. And we’ll confirm all of this – including exclusive bandwidth – in writing through individually negotiated SLAs.

Everything at a glance thanks to transparent monitoring and reporting.

Want to know the current status of a specific message? When was it sent? How about when your recipient received it? Sure. Our web-based reporting and administration portal (EAS) provides you with 24/7 access to a multitude of monitoring and analysis functions. From real-time monitoring of individual messages to long-term reporting for departments or subsidiaries. You have full control over your communications at all times. Company-wide.

Reliable delivery is essential.

What applies to customers when they shop online applies just the same to employees when they log in via 2-factor authentication or to a lab report that needs to be sent straight to the operating room: The entire process is significantly disrupted if an expected message arrives too late or not at all. That is why we at Retarus make sure that your messages arrive quickly and reliability at their destination. Thanks to our innovative bounce, traffic, and reputation management, intelligent routing, CSA certification, NeverBusy Technology, active carrier management, and global hyper-aggregation, just to name a few features.

This means substantial savings across the board. You’ll benefit from consolidated telecom infrastructures and providers, usage-dependent billing, and reduced manual work through increased process and workflow automation.

Along with automating processes and integrating applications and systems, Retarus specializes in IT cloudification and data center consolidation, as well as modernizing and safeguarding communications infrastructures. All your requirements fulfilled in one place. The Retarus Messaging Platform helps you implement digitization projects. It provides communicative flexibility to your cloud, hybrid, or on-premises solutions. It increases reliability to your VoIP/All-IP environments, enhancing fax capabilities on MFD and throughout digital workplaces.

Smooth integration across all applications and ecosystems.

Cloud Fax, Transactional Email, and Enterprise SMS can be quickly and easily integrated into any application or system via standard interfaces and APIs. Be it Microsoft 365, Google Workspace, Salesforce, SAP, or any legacy application. And if the situation is a little more complex or customizations are needed? No problem at all. The Retarus Enterprise Integration Team can handle not only standard, but customer-specific requirements as well.

Maximum protection of your data. 100% compliant.

Our international subsidiaries and globally distributed data centers help you implement locally applicable privacy requirements by processing your data in the legal area that applies to you. We are a family-owned company with headquarters in Germany. When it comes to data processing in Europe, we guarantee 100% GDPR compliancy. All data is processed exclusively in our own data centers without the use of any hyperscalers. Furthermore, Retarus supports numerous national and international control and industry standards and requirements, such as ISO27001, SOC 1, SOC 2, HIPAA and PCI DSS.

Digital downstream processing thanks to automated pre-processing.

The optionally available Process Automation Modules of the Retarus Messaging Platform instantly prepare your incoming documents for further digitized processing in downstream workflows and systems. We use intelligent routing that can be based on sender, recipient, or even content using barcode or text recognition. We receive, digitize, select, classify, and deliver according to rules you define. Communications can be seamlessly routed to people, team inboxes, systems, or applications. More so, data can be further integrated such as into any EDI processes. To this end as well as for customer master data recognition, unstructured data in incoming fax documents can be automatically converted into structured data using Intelligent Document Processing.
