It's a pretty straightforward solution.
The WAN aggregation feature is the most valuable.
The best feature is the backup capability, where all of the users' computers are tied into a central data repository.
The most valuable feature is its reliability.
It has the ability to prioritize, providing an automatic optimization. I can put it in a hierarchy and know that certain devices will be prioritized over others. It is able to identify the traffic. It can pick out whether if its a Zoom meeting (or something like that), then it's able to put that somewhere in the hierarchy based on the traffic type.
I find the most valuable to be the compression and exchange replication.
TCP optimization... caches a particular TCP connection and the next time a user uses that connection he will reach the destination easily.
I really love the auto-tunnel creation feature.
It's a stable solution.
The most valuable feature is the caching.
