Hi, the essence of this product is not the vendor that runs the edge device at the branch office, therefore we support integrations with all kinds of routers and SD-WAN machines, not just Check Points at the branch office.
If your edge device at the branch office is a Check Point, then you should connect to NSaaS using IPsec. Other devices such as Cisco or SilverPeak can connect to NSaaS using GRE or IPsec.
As this is Early Availability, not all features are included at the moment. Identity Awareness support is coming shortly. Let me know privately if you have a branch office site that you wish to connect.
