We occasionally get asked generic security questions related to our hosted/SaaS provision - to speed the process of answering these we have taken a selection of the typical questions that we are asked and have posted them below.

This should be viewed in conjunction with our Company Policy Statements page, which has more detailed information on specific areas.

Basic System Overview

We have produced a support page that covers, in broad terms, the architecture and flow of the SaaS system. This isn't a 'deep dive' into technology but should give a good overview of the principles in play. The page also takes you through a basic User Journey of the system - Click here to view.
