What do I think about the scalability of the solution?
Because we are using the hardware, we are not able to scale. On the VM, it is scalable, but we have got stuck on some areas. Therefore, scalability is an issue.
How are customer service and support?
Technical support is very good. I would give them a ten out of ten.
How would you rate customer service and support?
Positive
Which solution did I use previously and why did I switch?
The previous solution, Check Point firewall, is having lots of issues. The main reason is that capacity planning was not sized properly. We are also not receiving the type of support we want. Because of these reasons, we switched to Palo Alto Networks K2-Series.
How was the initial setup?
The initial setup was straightforward only because Palo Alto professionals helped us with it. Without the professional service, it would have been a little bit complex.
What about the implementation team?
We used Palo Alto Professional Service for help with deployment.
What other advice do I have?
Nowadays, all of the firewalls provide everything. Palo Alto may cost a bit more, but it provides skilled engineers who are readily available. Deployment is easy as well, in comparison. I would rate this solution at eight on a scale from one to ten.
Which deployment model are you using for this solution?
Hybrid Cloud

Technical Advisor to COO at a comms service provider with 51-200 employees
Stable and scalable overall but support is worse than most competitors
Pros and Cons
- "Palo Alto firewalls are scalable enough. We have about 110 employees in our company, and we are about to expand to 130."
 
- "If we have issues, they take anywhere from two days to a week to respond. I even wrote to their CEO because there was no response. When it comes to support, this is the worst company."
 
What is our primary use case?
I'm a telecom operator, so all of my IT and network management stuff is behind this firewall.
What needs improvement?
Palo Alto K2-Series firewalls could use some technical improvements, like main and standby, as well as FTU and STU support. In addition, they should upgrade the CPU, and there are so many other things that I cannot think of off the top of my head.
For how long have I used the solution?
I've been using Palo Alto firewalls for two years.
What do I think about the stability of the solution?
Product-wise, it's stable, but it takes too long to switch between main and standby — maybe 10 to 12 seconds — and sometimes my traffic cuts out, yes. Also, the CPU processing power is not so good.
What do I think about the scalability of the solution?
Palo Alto firewalls are scalable enough. We have about 110 employees in our company, and we are about to expand to 130.
How are customer service and support?
Most firewall companies offer similar products, like Fortinet, etc., but Palo Alto support is not as good as its competitors. Palo Alto is almost zero. If we have issues, they take anywhere from two days to a week to respond. I even wrote to their CEO because there was no response. When it comes to support, this is the worst company.
How was the initial setup?
We have no idea how complicated the setup is. An agent from Palo Alto did all that and then conducted some training. And if we need something, we have to call the agent.
What's my experience with pricing, setup cost, and licensing?
The price is high, but we've already purchased these two boxes, so we have to continue using them for some time. Unfortunately, the salesperson we worked with isn't a Diamond-level agent, so he couldn't give us good discounts. But maybe a lower price is possible.
What other advice do I have?
I rate Palo Alto K2-Series Firewall six out of 10.
Which deployment model are you using for this solution?
On-premises
