Will add additional comment to the above,
By adding the product to HCL, Check Point commits on full support for it under specified software version.
It means end customer will be fully covered by TAC and R&D in case he will need an assistance.
Check Point appliances are passing all needed tests by default. This is our main branch of hardware.
However, understanding the needs, we are trying our best to certify also 3rd party equipment which has bunch of varieties. Also we are not focusing on one specific brand, proving wide angle of choice.
This concept has pros and cons as any other. And despite of numerous pros, the cons is a time needed for certification.
This why we decided, first of all, go based on customer's requirement and considered RFE as the most suitable way of getting the certification requests.
It helps to get organized information, understand the exact hardware requirements (as again 3rd party has many different option for extra hardware), prioritize and track all of them.
So, for those who need to use an open server which is not in HCL,
Please contact with your local SE to discuss your needs and submit RFE to Check Point.
