I am creating a SaaS that will be delivered through a Vertical Information Portal (VIP).
In my research I have found that by developing a custom lean web browser and installing it on the clients platform, I can better restrict access to the portal on the web by only allowing this custom browser to access it.
I realize there is a threat of duplicating the the client browser. but I feel it is better option instead of any browser being able to access the portal to receive the payed services, and much easier to flag for piracy.
However, in regards to security of a custom browser, I have not been able to find any useful information. I would elaborate on this point, but unless I am missing something (which is probably the case), I have nothing to go on.
Can you point me in the right direction to make a thorough threat assessment on a custom browser build for a VIP delivered SaaS?
By looking at the possibilities of a customized connection from server to client, I am not trying to re-invent the wheel, but looking at innovative options to make improvements to the wheel.
I do not make the assumption that any system is totally secure, and I fully believe the practice of IT Security is a constant work in progress that must be improved on (hence, the purpose of this question).
