Hi Graeme - I have been working very closely with the Qlik Cloud team and will be able to address your concerns. Is there anything specific you would like to go over in regards to security?
Currently - the Qlik Cloud - is built to deliver a variety of cloud based services. In the first phase of the Beta program, we are offering the Sense Sharing service. Which allows Sense Desktop users the ability to freely share (during the Beta only) a view only or read-only or interact-only (however you want to call it) version of the Sense app to up to 3 additional users. In other words - no editing or development capability. The registration and invitation process is very similiar to the way dropbox or a hosted file share would work.
A desktop user registers with the Qlik Cloud Sharing Service
Uploads a .qvf file (Sense App)
Sends and invite to those they want to share it with
The recipient registers and views the app.
There is a video on this topic and it will be posted shortly to the Qlik Cloud Community section in the Beta programs area - it will be accessible here: Sharing on Qlik Cloud Beta
In regards to security - we can provide a few levels of detail here - so when you have a minute - please outline any concerns and we can address appropriately.
