We have been using N-Able for over 3 years now. The Server side has been offline once during an upgrade from one version to the next. We are extremely happy with the software, except the pricing could be a bit better.

We started our operations using OpManager .. but realised quickly this was not a good choice seeing that the software was offline more often the customer Nodes. How could we monitor customers when our monitoring software doesnt respond. THis is a problem we have not faced with N-Able at all. They are constantly improving the product, help out with the basics right down to even auditing your company see if you understand MSP and what it means.

If we had to choose again we would defnitly choose N-Able. Even local support in Holland. Only thing we would like to see is more support for FreeBSD in the future. Software comes in variuos versions from probe / agent . The probe and agent do not use a lot of CPU / mem on the Node side.
