We now offer Endpoint Management as a Service free of charge, provided you purchase and maintain SandBlast Agent subscriptions.
It does have a couple of limitations, as described in the documentation: https://sc1.checkpoint.com/documents/Endpoint_MaaS/html_frameset.htm
The docs also explain how you register for this service.
If you have more than 10,000 seats, please work with your local office to ensure proper support.
In terms of moving your existing Endpoint configuration to our cloud management, I believe this can be done with TAC assistance.
