What is our primary use case?
We use Sangfor NGAF's next-generation firewall as a security firewall which includes a web application firewall, web app filtering, and URL filtering. It also helps us defend against botnet attacks and similar threats.
In my office, there are about three people who are involved in the direct use of it, although not too many others know about the firewall yet because it's a new product.
What is most valuable?
The absolute best part of Sangfor NGAF is their support. It's a 24/7 support channel, and the last time I requested their assistance I got a reply within three minutes. They helped solve the problem immediately.
Sangfor also gives you a warranty for any issues or defects with their hardware. If you find any issue, they will replace the hardware within five working days. We send any hardware that is faulty to our local country partner and they will do the RMA.
When it comes to deployment environments, I like that you have options. If you want a hardware firewall, then you can use their hardware. Conversely, if you want a cloud firewall, then they can provide that, too.
What needs improvement?
I would be happy if Sangfor developed a firewall designed specifically for home use, as well as for small businesses such as clinics and so on. A household version of the Sangfor firewall for your personal computer or laptop would be ideal, in my opinion.
For how long have I used the solution?
I have used Sangfor NGAF for about four years.

What do I think about the stability of the solution?
Sangfor NGAF is very stable and comes with a hardware warranty where they will replace the defective hardware within five working days. So if something goes wrong, you don't have to fix it, but instead you can just get it replaced.
What do I think about the scalability of the solution?
Sangfor have divided their firewalls into several categories, so you have multiple options with regard to scalability and how many users you need to account for.
For example, if you've got low bandwidth requirements, you might want to deploy the 5200 model. But as you go into higher bandwidths, you will have to deploy the 5300 model or higher.
How are customer service and support?
My recent experience with their support was wonderful. I had an error come up on my Google Chromecast device, where it would simply restart over and over again because it was blocked on the firewall.
When I opened a ticket with Sangfor support to help solve this problem, one of their support members called me within three minutes and asked about the issue. They discovered what was wrong and resolved it. From this experience alone, I can say their support is the very best.
How would you rate customer service and support?
How was the initial setup?
It's very easy to set up. They provide support services on a 24/7 basis, and with this support it makes everything easier to install, configure, and troubleshoot. I would give them a perfect score for support.
What's my experience with pricing, setup cost, and licensing?
If you know you have around 200+ computer users on your network, then the Sangfor NGAF 5200-F-I model would be the minimum recommended model for that amount of users. This model includes modules for packet filtering, deep packet inspection, malware scanning, DSCP filtration, and many other features.
The 5200-F-I model costs around $5,000 once-off, and then around $1,000 per year for the license renewal for both the hardware and software. The $5,000 payment includes deployment, all the modules, the initial license costs till the next year, and deployment support calls. It covers basically everything to get started, and I would rate the pricing as 5/5 stars in terms of competitiveness.
Which other solutions did I evaluate?
When evaluating Sangfor NGAF with its competitors' products, the first thing I would note is that the other solutions are not likely to fulfill their hardware warranties within five business days, as Sangfor does.
Another advantage of Sangfor is cost. Many other firewall companies offer their products at a high licensing cost, and the modules that come with these solutions are also very costly. In contrast, the Sangfor firewall is not only highly affordable to procure, but it's also very cheap to deploy.
Finally, when you compare Sangfor with Fortinet, for instance, there is a big difference when it comes to configuration. With Fortinet, you typically have multiple different products to configure for various purposes, such as FortiEDR and FortiAnalyzer. All these products from Fortinet have to be configured with the different algorithms and modules that they suggest. But in Sangfor NGAF, everything is in one window.
What other advice do I have?
I would rate Sangfor NGAF a ten out of ten.
