What We Do for
Our Customers

DH2i frees our customers from vendor lock-in and gives them the freedom to securely connect any mix of platforms and infrastructure, anywhere, to create a fully-custom, optimized database environment to meet the needs of their unique workloads.

DH2i prides itself on the support we provide our customers, and from the initial demo experience to production deployments, we can help you architect the perfect, customized high availability and network security framework for your critical database environments.

How We Got Started

DH2i was founded in 2010 by Don Boxley Jr. and OJ Ngo: entrepreneurs with a history of building high availability solutions that optimize the deployment of enterprise applications like Microsoft SQL Server.

Don and OJ met while working on HP’s PolyServe product. When PolyServe went end-of-life, Don and OJ knew they could develop high availability software that would be more efficient, adaptable and expandable. They were right, and DH2i has been innovating with high availability solutions and network security solutions ever since.

The major changes being driven by advancements such as IoT, edge computing, mobile, and cloud are creating conflicting demands for secure connectivity. The traditional ‘Castle & Moat VPN drawbridge’ security model was not designed to meet those demands.
