I have been working on this Citrix SD-WAN solution since last year but haven't seen any issues. It appears to be a stable solution for us. 

The solution is very stable. I haven't had one outage in any of our SD-WAN environments. That's obviously taking WAN links out of the equation. The appliances themselves are super stable. We haven't had any appliances crash or anything like that. We've had one or two where there's been power damage. However, those environment variables are at play. Still, from a stability point of view, it's very stable.

I would rate the stability six out of ten.

It is stable. 

I would rate the stability of the solution as a nine out of ten.

It is stable.

It's a stable product. We have encountered a few issues, like glitches and bugs causing some of the devices to fail, while also facing a hardware failure.

We haven’t had any real issues with stability. We put it in for countrywide operations, however, and we expected there would be a lot of returns. There are actually very few, and even these returns were out of Citrix's control. For example, we had a few appliances return back due to lightning and the resulting power surges. Besides that, we rarely have failures, so the client is happy.

We have deployed this solution for 16 sites and we have not had any issues with the stability.

The solution was stable.

The solution is stable. We only require two people for maintenance. 

It is very stable. 

It's been three years we have deployed this product and I have not had any downtime or any issues with the product. The product is stable.

The stability is excellent.

This is a stable and mature product. We have few admin support cases and the maintenance is very limited.

The stability of the solution is good.
