The ability of this system has been great, I have used many different tools over my career in IT Security; however none compare like CCF! It's by far one if not THE best out there when looking at all aspects as well security related ones specifically (such us PCI Compliance).
There are some things about CFA which can be improved upon such as being able implement more complex queries than just "where". However these issues aren't deal breakers since they do exist within other products too so you're likely going find something else better suited your needs/budget anyway :) As stated above we were using another product previously called PCA where our clients could search through various databases without having access / permission set up ahead time - This was very useful especially during audits etc.. We needed similar functionality here though only via API instead because users would need full.
