I can't say that there's anything valuable in the product now. We've reached end-of-life with it and are now getting an alternative solution.
What needs improvement?
The biggest issue was that Juniper stopped developing, so we had to look for another solution. If they were to continue development, I would like to see a decent portal functionality, WPA3, and support. Probably some kind of API as well.
What other advice do I have?
Deployment of the product took a few months and we used a consultant for that purpose. We have recently moved to implementing Aerohive. They are an ongoing business so the product is fully supported and it has the latest technology, and it's a cloud-based solution. I would rate the Juniper a seven out of 10.
