The best thing about this product as I can say is that it supports both WAFD and BGP, which makes it really easy when deploying in my network. It also has all required features like IPsec VPNs, IPSEC tunnels etc apart from the native L3VPN feature. Even though it's one of the expensive products out there but still gives you great value. If your looking for an open source solution then go ahead otherwise if you are fine with using proprietary solutions then definitely try this one since the pricing isn't much high considering what you get after buying the software. We have been able to implement our own Private Cloud along with WAFD and its working well so far. Our IT department doesn't need any training or support because we have hired some professional engineers just to configure the entire environment including hardware provisioning. And yes their service level agreement works perfectly and they handle everything related to our infrastructure even at late hours without charging anything extra.
