The on-prem SMP product was originally developed by Sofaware a couple of decades ago for Safe@/UTM-1 EDGE appliances.
It runs on now legacy versions of Windows OS and Check Point code, which creates some obvious maintenance/stability challenges.
Most of our focus/efforts have been on improving the Cloud-based SMP service, which is the most appropriate solution for the majority of our customers.
Transitioning from on-prem SMP to Cloud-based SMP is something many customers have done, both large and small.
Please open a TAC case and you will be guided through the process.
