Solutions
rEngin® is available in three distinct variants

rEngin® Partner: A Comprehensive Approach to Registry Success
The rEngin Partner Solution is our most complete and strategic service offering — designed for registries that want an embedded, long-term technology and operations partner.
With this solution, DNS.Business assumes a hands-on role in your registry’s day-to-day operation, using our own proven technology and expertise to ensure seamless, compliant, and efficient performance across all registry functions. It’s more than Software-as-a-Service — it’s a partnership built on operational excellence, technical depth, and shared success.
This model is ideal for medium to large TLDs and SLDs (50,000+ domains), but it’s equally valuable for smaller registries with high growth ambitions.
Key Benefits of the rEngin Partner Solution
- End-to-End Technical Management
We handle all backend registry functions — including EPP, OT&E environments, DNSSEC, auction systems, rights validation, reporting, and more — backed by enterprise-grade infrastructure and expertise. - Seamless Migration and Onboarding
Our experienced implementation team ensures smooth transition from legacy platforms with minimal downtime or service disruption. - Strategic Partnership and Advisory
Beyond technology, we provide ongoing business and operational consulting to help you identify growth opportunities, improve efficiency, and optimize your namespace strategy. - Scalable, Secure, and Proven
Whether hosted locally or within our global infrastructure, your registry benefits from the same high availability, data integrity, and compliance standards trusted by leading ccTLDs and gTLDs.
The rEngin Partner Solution is the ideal choice for registry operators seeking a turnkey solution backed by deep industry knowledge, operational resilience, and a commitment to long-term success.

rEngin® SRS: The Shared Registry System
The rEngin SRS (Shared Registry System) bridges the gap between Registries and Registrars, creating a unified, shared domain marketplace.
This model delivers the full technical capabilities of the rEngin platform as a hosted service — eliminating the need for local infrastructure or capital investment. While DNS.Business provides and manages the backend systems; the Registry Operator retains full policy and managerial control.
The SRS model is ideal for registry operators who prefer a flexible, cloud-based deployment, enabling them to focus on strategy and business development while leveraging our robust, shared infrastructure.

rEngin® Client: Your Locally Hosted Registry Solution
The rEngin Client is a licensed, locally deployed version of the rEngin platform — designed for registry operators who prefer to manage and host their own systems while relying on our technology foundation and second-line support.
This option delivers full control over your infrastructure and data, while benefiting from rEngin’s proven reliability, feature set, and technical resilience.
