What is our primary use case?
We use them to do quite a bit of URL filtering, threat prevention, and we also use GlobalProtect. And application visibility is huge for us. Rather than having to do port-based firewalling, we're able to take it to an application level.
How has it helped my organization?
We have quite a number of security pieces that are implemented for our network, such as a DNS piece, although we're not using Palo Alto for that purpose. But with that, in line with our seam, we're able to better distinguish what normal traffic looks like versus what a potential threat would look like. That's how we're leveraging the NG Firewalls. Also, we have separated the network for our databases and we only allow specific users or specific applications to communicate with them. They're not using the traditional port base, they're using application-aware ports to make sure that the traffic that has come in is what it says it is.
Machine learning in Palo Alto's firewalls, for securing networks against threats that are able to evolve and morph rapidly, has helped us out significantly, in implementation with different security software and processes. The combination allows our security analysts to determine the type of traffic that is flowing through our network and to our devices. We're able to collect the logs that Palo Alto generates to determine if there's any type of intrusion in our network.
What is most valuable?
The machine learning in the core of the firewalls, for inline, real-time attack prevention, is very important to us. With the malware and ransomware threats that are out there, to keep abreast of and ahead of those types of attacks, it's important for our devices to be able to use AI to distinguish when there is malicious traffic or abnormal traffic within our environment, and then notify us.
The fact that in the NSS Labs Test Report from July 2019 about Palo Alto NG Firewalls, 100 percent of the evasions were blocked, is very important to us.
What needs improvement?
The SD-WAN product is fairly new. They could probably improve that in terms of customizing it and making the configuration a little bit easier.
For how long have I used the solution?
I've been using Palo Alto NG Firewalls for about five years.
What do I think about the stability of the solution?
The firewalls are very stable. We've had no issues with downtime.
What do I think about the scalability of the solution?
They're very scalable. Because we use Panorama, we're able to have global firewall rules for areas that we want to block, across the network, for security reasons. We just push those down to all the devices in one shot.
Our corporate site has about 500 users, and our 14 remote sites, because they're retail, usually have anywhere from five to 10 users each.
How are customer service and technical support?
Their support is generally very knowledgeable. Sometimes it depends though on who you get, but they've always addressed our issues in a timely manner.
Which solution did I use previously and why did I switch?
We were using older versions of Palo Alto's firewalls and we also had Cisco firewalls in our environment.
How was the initial setup?
For our remote stores we're able to use Panorama, along with Palo Alto's Zero Touch Provisioning hardware. Once a device is connected to the internet and can communicate back to our Panorama, it just pulls the configurations. That means it's very easy to deploy.
It took about two to three months to deploy about 14 sites. That wasn't because we were having issues, it was just the way we scheduled the deployment, because we had to bring down different entities and had to schedule them accordingly with a maintenance window. But if it wasn't for that scheduling, within a week we could have deployed all of the remote sites.
For our implementation strategy, at our corporate site we had both old and new firewalls sitting side by side on the network. As we went to a remote site we would take them from their legacy Cisco and cut them over to the new firewall. Once that was done, we moved all of the firewall rules that were on the old firewall over to the new one.
When it comes to maintenance and administration of the firewalls, my team of five people is responsible. We have a network architect, a network specialist, two senior network specialists, and a security manager.
What about the implementation team?
We did it by ourselves. We have a certified Palo Alto engineer on staff and he did all the installation.
What's my experience with pricing, setup cost, and licensing?
Definitely look into a multi-year license, as opposed to a single-year. That will definitely be more beneficial in terms of cost. We went with five-year licenses. After looking at the overall costs, we calculate that we're only paying for four years, because it works out such that the last year is negligible. If we were to be billed yearly, the last year's costs would be a lot more. With the five-year plan we're saving about a year's worth of licenses.
Based on the quantity of devices we purchased, we found that the hardware price was actually cheaper than most of the other vendors out there.
If a colleague at another company were to say, "We are just looking for the cheapest and fastest firewall," given my experience with Palo Alto's NG Firewalls, my answer would depend on the size of the company and how much traffic they're going to be generating. Palo Alto is definitely not the cheapest, but if you scale it the right way it will be very comparable to what's out there.
Which other solutions did I evaluate?
One of the things we like about Palo Alto is the fact that the hardware appliances we have are not impacted in terms of resources. The CPU and memory stay low, so we don't have a bottleneck where it's trying to process a whole bunch of traffic and things are slow. We were looking at various brands because we were going from older hardware to newer, and we wanted to evaluate what the other vendors were doing. After that evaluation, we were comfortable that Palo Alto would be able to handle all of our network traffic without impacting performance.
We looked at Fortinet and Cisco. Cisco is a bit pricey when compared to our Palo Altos. Fortinet was definitely cheaper, but we were skeptical about their performance when we bundled all of the features that we wanted. We didn't think it was going to be fast enough to handle the network traffic that we were generating across the board. We believe Cisco would have handled our traffic, but their next-gen platform, along with SD-WAN, required us to have two separate devices. It wasn't something that would have been on one platform. That's probably why we didn't go down that road.
Part of what we considered when we were looking around was how familiar we were with the technology. That was also a big area for us. Most of the guys on our team were pretty familiar with Cisco and Palo Alto devices. They weren't too familiar with Fortinet or Check Point. We narrowed it down based on if we had a security breach, how easy would it be for us to start gathering information, remediating and troubleshooting, and looking at the origin of the threat. We looked at that versus having to call support because we weren't too familiar with a particular product. That was huge for us when we were doing the evaluation of these products.
What other advice do I have?
Other than the SD-WAN, everything else has been functioning like our previous setup because it's a pretty similar license. The way that the new hardware handles URL filtering, threat protection, and GlobalProtect has been pretty solid. I don't have any issues with those.
Overall, I would rate Palo Alto NG Firewalls at nine out of 10. It's definitely not the cheapest product out there. Cost is the main reason I wouldn't put it at a 10.
