The most valuable feature is that it also works as a next-gen firewall because it has security features.
Which solution did I use previously and why did I switch?
We also used VeloCloud. It is a cloud-based application platform, it's integrated into the cloud that you don't need to have applianced, unlike Cato.
What other advice do I have?
If you really want to have a solution that has an easy deployment and provides SD-WAN and firewall abilities, go with Cato Networks. I would rate it an eight out of ten. Not a ten because they don't offer a VPN for the firewall. They should add more sophisticated security features. It should also be integrated into the cloud.
