Low cost but unresponsive technical support and very unstable performance
Pros and Cons
  • "The solution can scale well."
  • "Sometimes it reboots when you least expect it, and that's the main issue."

What is our primary use case?

We primarily use the solution as a firewall and a router. We use it for freelancing.

What is most valuable?

The solution is good for freelance and routing, as we don't have a separate router. It's usable for me, for my purposes.  There are some filtering options such as peer-to-peer blocking and things like that. The solution can scale well. The cost is very low. 

What needs improvement?

I have never seen it in any company that I've worked with before, and I would advise other companies not to buy it. The device is really awful It doesn't work well. It is unreliable. They tried to put something professional on a market, however, it's anything but. Technical support is unhelpful and does not resolve issues quickly (or at all).  From the WiFi access points, the performance is really bad from Zyxel. We have about 26 WiFi access points and still, it does not work as expected. I need a next-gen firewall next time. I want to be able to do something about malware, et cetera, and that's not the case at this moment. It's a traditional firewall. It doesn't do that. Sometimes it reboots when you least expect it, and that's the main issue.  When you go on the internet, and you read about it, you'll find more people with the same problems you are having, and they do not get resolved by the company.

What do I think about the stability of the solution?

The stability is unreliable and the performance is bad. I would not say that the solution works very well in general.

What do I think about the scalability of the solution?

The scalability is good. We bought extra licenses for more access points that are quite easily put in for some extra storage for logging. That was not that difficult to do. It's easy to expand.

How are customer service and support?

The support was really bad. I've had support from them and it took me over three months to get one thing resolved. In fact, it was not resolved in the end. The experience was really bad. You try to call them, you try to reach out and send them emails, and they don't respond.

How was the initial setup?

The initial setup has a moderate level of difficulty. You need to have so much knowledge, however, that's true with every firewall.

What's my experience with pricing, setup cost, and licensing?

We have a yearly licensing agreement with the company. The licenses are okay. The costs are pretty low.

What other advice do I have?

We are a software company. We build software. We do not sell the product. We are using the latest, most up-to-date version of the solution.  I would steer other potential users away from this product. I will never advise this product to anyone. I have never seen it also in a company. I'd rather suggest a company choose another brand.  I'd rate the solution at a three out of ten. I really have not had a good experience with the product.

Which deployment model are you using for this solution?

Disclosure: I am a real user, and this review is based on my own experience and opinions.
