From a hardware stability point of view, Huawei is a much better solution.

The stability of Juniper SRX is good, but there have been instances where it did not perform well. However, when compared to another vendor, such as Huawei, it has been deployed in our backbone for many years without any issues. This does not mean that Huawei is better than Juniper, in terms of functionality, Juniper is superior.

We had suggested an HA-based environment, or architecture in the majority of places that we have implemented Juniper. In these cases, it has been very stable. There have been other products that we couldn't upgrade to the latest format, but Juniper could always be upgraded. It always worked and never crashed.

Juniper SRX Series Firewall is a stable solution, but it depends on how you set it up. You can make the solution unstable if you want to, but it will be stable if you set it up correctly.

Director & CIO of IT services at Connectivity IT Services Private Limited

I would rate stability on a scale of one to ten. If ten is best, I would rate a nine-point-five. I would not rate anything a ten in this industry in any case because nothing is perfect and there is always room for improvement. It is very robust. Because the product is robust and very agile that carries over well into the potential for reliability.

We have had glitches that necessitating rebooting the device. For example, a couple of times, they just stop routing on certain VLANs, and one time, it was our server VLANs, so our DNS was down and no one could get to anything. People thought that our internet connection down but actually, it was the DNS and the routing to it had been stopped.

In terms of stability, everything was okay except for one situation which happened about three years ago. There was an upgrade which was released. Once we got the upgrade on the software, it would crash and it wouldn't work as it had before, so we had to downgrade to the previous version. Once we started using that there was no problem.

While the solution has been running stable, one device has also malfunctioned. We had some issues with Juniper in general. It was regarding the firmware and some box, or something like that. We've needed to contact our reseller more frequently to fix the issues that are occurring when using the device.

Regarding stability, it's pretty much working in a stable way. I haven't had any issues regarding, let's say, speeds or connectivity or general day-to-day use, when users connected on the switches and accessing the internet, and so on. That said, sometimes with the devices, strange issues happen.

GV

It's cool. I would say it's one of the most stable services. Providing for redundancy is a bit challenging, but it actually is something that can be worked upon because they have a different concept of highway building, as opposed to general people doing stuff. I would say it is a good, stable product, except for the problematic part of it. If people are not aware of how to deal with it, it can be very cumbersome.

The stability is quite good. It's very reliable as long as your power is okay. It's a good device and good software and is a great piece of equipment, however, if your power has any issues, then you are likely to lose it after power surges.

Its stability isn't bad. In two years of supporting this device, I had only one issue. I had an incident when one of the SRXs in a cluster couldn't learn ARP, and the request didn't move between cluster units. I had to fix this manually, which wasn't really cool because I had to get up in the night because of this incident.
