Does the API require an external connection to perform tests?
(i.e do we need to open our perimeter firewalls to use the API?)
Yes, you do have to give us access. (More detailed explanation coming)
Is there any working model present with you which you can demo for us?
Yes, we can either give you a live-demo, where we go through the setup and exemplary results. On request, we can also send you example test results.
