What is our primary use case?
One of our use cases is that it is used by our internal users, our employees, when they need to work remotely. They'll be out in the field and, wherever they have an internet connection, they run the GlobalProtect client, connect, and they can access our resources as if they're in our building. For example, we have health inspectors who go to different sites.
Of course, we're doing more teleworking like everyone right now. Also, our admins all use it because that's how we get in and do remote work. And, periodically, we have contractors or vendors who need remote access. We'll build an account in AD and either have them download the client and connect to us, or if they currently use the GlobalProtect client for some other VPN connection, we can just provide our gateway and they can use their existing client to connect to the resources that we allow them.
We also have a clientless VPN by Palo Alto. It's a website where you can enter your AD credentials, and it will publish internal web apps that you can access through a browser. We have some users, and a set of contractors, who use that to access some of our internal systems for COVID response.
It's a cloud-based VPN, but it's managed from our Panorama instance, which is on-site. There's the GlobalProtect client that gets installed, that's the VPN client on your laptop, and that automatically updates from the cloud when a new version is available.
How has it helped my organization?
Prisma Access is our first cloud-based VPN solution. I like that aspect because I don't have all the traffic hitting my firewall interface directly. Users go to the cloud, wherever they are, and connect to some kind of cloud. It will grab their config, and our firewall doesn't see any extra traffic from that. That's awesome.
Because we are in the health sector, the clientless, web-based VPN that we're using has allowed us to partner with some external companies to do contact tracing for COVID. That means that if someone is positive for COVID, those companies track back to the people they have been in contact with and try to find the source. The fact that the only way a couple of hundred of our employees can access our records at any time is through the web-based VPN has really improved our ability to respond to the pandemic.
What is most valuable?
I like it because it's very easy to use. You install the client and you have to know your gateway, but that's something we give to our users. Beyond that, it takes about three seconds to train them on how to use it. And it just works well. That's great for us because it means less administrative time.
It's also nice that Prisma Access provides all its capabilities in a single, cloud-delivered platform.
The thick client secures non-web apps in addition to web-based apps. If you have the client installed on your laptop, it's a completely secure VPN connection and anything you run will be secured by it. The clientless VPN, the web-based one, only allows you to redirect to URLs; it's only web. Being able to access non-web apps is important to us because it's how we get our remote work done. Not everything is web-based. We have to run applications and access Windows shares and the like.
This ability helps decrease the risk of data breach. Information security is more and more a huge concern for everyone. Knowing that everything's going across an encrypted tunnel, and that we can manage what is accessed by which user, are huge benefits.
Another important aspect is that Prisma Access provides millions of security updates per day, because security has really become our number-one focus lately. That feature is very good.
For how long have I used the solution?
I've been using Prisma Access by Palo Alto Networks for about two years, maybe a little longer.
What do I think about the stability of the solution?
It has been very stable. We've had a couple of small outages, but overall it's very trustworthy and stable.
What do I think about the scalability of the solution?
It's cloud-based, so it's infinitely scalable. For us, it has worked fine. We went from a few users at first and we built up to hundreds.
It's our clientless VPN that really builds up our user count. It is consistently between 300 and 400 users. It rises and falls depending on what kind of campaign we're doing. If a new COVID variant is discovered and we have to ramp things up because of CDC guidance, the user count will bump up.
How are customer service and support?
The one thing that I've been a little bit disappointed with is when we have had to open cases with Palo Alto about Prisma Access issues. Versus their other platforms, like their firewalls, where we tend to get really quick responses and very definitive answers, the few tickets I've had to open for Prisma Access have taken them longer to respond to. And they haven't necessarily given me the kind of answer I was looking for, meaning a fix to the problem. Maybe this technology is not as cut and dry as some of their other technologies. But I think they could improve their support offering for Prisma a little bit and put more expertise in place.
Overall, I'm very happy with Palo Alto's support. I'm not saying that their Prisma support is awful. It just hasn't been quite up to par with other support I've seen from them, which has been pretty phenomenal.
How would you rate customer service and support?
Which solution did I use previously and why did I switch?
For VPN, we used Cisco AnyConnect. The switch to Prisma Cloud was part of a platform switch from Cisco ASA to Palo Alto firewalls.
We also have other solutions, such as a virtual desktop solution that is available externally. Some of our users use that and others use the VPN.
How was the initial setup?
The setup was medium complex. Because of the way we're doing it through our Panorama, it's a little more complex than it would be on the cloud-only solution. There is definitely some complexity to it.
What about the implementation team?
I wasn't involved in the initial deployment of it, but our organization worked with a vendor called CompuNet, a company with Palo Alto expertise. I would guess it took one to two days to get through everything and test it.
Which other solutions did I evaluate?
The evaluation happened before my time here, but we had people who had worked with Palo Alto previously. They knew its reputation and were happy with it. I think the switch happened directly.
What other advice do I have?
It functions like a lot of other VPN solutions. It's not special in that sense. It just works.
I have spoken with another agency that was looking at Prisma Access. The one thing they weren't aware of was the clientless, web-based VPN that is part of the product. They were pretty excited when I explained to them how we use it. So make sure you review the full feature set that Prisma Access offers. It may be broader than you expected.
We are using it as a hybrid solution where we manage it through our onsite firewall. There is a Prisma Access full-cloud solution where you do all the management there. If we were to start over again today, I would probably go full-cloud. That would ease the management a little bit. People who are using the cloud-only solution probably have fewer hoops to jump through to get certain things accomplished. But we've been fine.
The biggest issue I've run into is that most of the documentation for Prisma Access is based on the full-cloud model, as opposed to our hybrid implementation. It's a little trickier to find out how to implement some of those changes through Panorama. There are also some connectors you have to set up to make sure that your Panorama is talking to the cloud the way it should. Those wouldn't be necessary in the cloud version, and that means it's probably a little easier to sync your AD, set up your users in the cloud, and you're done. Everything is already on the cloud.
Overall, I'm very happy with the security provided by Prisma Access. Palo Alto is a security company and is always working on ways to make things more secure. I feel very confident that our data is safe using the solution, which is the whole point.
