For decades, the Radicati Group has been the leading analyst firm for all things email. In their brand-new 2025 Secure Email Market Quadrant, the experts have classified Retarus as a “Top Player”.

The era of relying solely on hardware appliances for email security is ending. More and more providers are aggressively pushing their customers to transition from on-premises solutions to cloud-based models. However, this shift is more than just an operational change. It’s also an opportunity to reassess providers and choose a solution that offers superior long-term security and flexibility on how to manage email infrastructures.

Retarus is adding a new deployment model via API to their Email Security portfolio. This offering is designed to complement our existing SEG approach, providing organizations with greater flexibility in how they secure their email infrastructures. The API implementation is particularly well-suited for organizations using cloud-based email platforms such as Microsoft 365, allowing them to easily enhance their email security without changing their infrastructure.

This past Tuesday, Retarus had the pleasure of hosting our very first Customer Advisory Board at our headquarters in Munich. The event brought together a select group of key enterprise customers who rely on our Retarus Secure Email Platform solutions, creating a platform for open exchange, collaboration, and valuable feedback.
