KoolReport is secured to be used inside web app. KoolReport main focus is not to build website, rather it power your website with reporting capability, drawing chart, create table, dashboard. More than often, KoolReport is used together with another framework like Laravel, CodeIgniter to do website constructing part. Those framework are proven to be secured.

Since KoolReport is not a separate application, rather it is a framework for reporting, or you can understand it is a library of common functions, methods, visualization that used alot to process data and visualize data. So it will need developers to build something meaningful based on the library. KoolReport will make development faster as it contains ready-to-use features that developer will not need to code. In term of security, you need not worry. My suggestion is you find a good developer who understand the osticket to help you extend it, incorporating report into it.
