Hybrid Servers



SigniFlow launched its first open-enterprise on-premise SigniFlow Hybrid Server in 2017, in response to the need for enterprise-level businesses’ need to have maximum control over highly sensitive documents, where international legislation is involved.

The term ‘Hybrid’refers to the combination of technology our solution employs – a dedicated hosted server, virtualisation technology and cloud-based cryptography.

Hybrid Customisation 

Image SigniFlow Cloud and On-premise Solution
SigniFlow offers bespoke solutions that cater to the specific needs of businesses of all types and sizes.

Although often referred to as an on-premise solution, the SigniFlow Hybrid server is at home in a private server room or data centre, as well as in any hosted environment (private or public-cloud) and in a secure cloud services platform, such as Amazon Web Services (AWS) or Microsoft Azure.

  • Customisation

    Our Hybrid Servers offer the ultimate customisation, rebranding, enterprise information control, and an unrivalled bespoke integration landscape.

  • Technology

    Our solution is a native cloud application that uses cloud computing frameworks and network-attached Hardware Security Modules (HSMs) to perform cryptographic signature operations.

  • Flexibility

    Although originally built for the enterprise, we realised our Hybrid Server solution needed to be more flexible and scalable, to cater to medium – and even smaller – businesses.
