Identity-based perimeter control has improved security and supports reliable remote access
Currently, we are working with vendors such as Palo Alto Networks PA-Series, Cisco, Check Point, and Citrix. Palo Alto Networks PA-Series is a better firewall. Deep packet inspection and threat prevention basically comply with whatever traffic is incoming and outgoing through the firewall. I do not think anything improvement is required. The thing is that Palo Alto Networks PA-Series works mostly on a license-based model. If you want to utilize any feature, you have to purchase the license. For example, URL filtering requires a license purchase. It simplifies the implementation because LDAP server profile can be integrated. Basically, that simplifies the implementation of access rule or security policy.

User has benefited from stable performance and effective completion of security tasks
I use it mostly for VPN and for some firewall solutions When considering my main use case with VPN, I can say that I got the Zyxel Unified Security Gateway, and it works fine. However, we are thinking about using a different solution based on open source because Zyxel Unified Security Gateway…

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Palo Alto Networks PA-Series is basically integrated with LDAP to fetch the identity of the users and we provide access based on the identity."
"The cloud-based aspect helps significantly. It integrates seamlessly with other Palo products like Prisma Cloud, offers robust VPN protection, and it's all in one convenient package."
"The solution is robust."
"The direct profiles is a valuable feature."
"Palo Alto Networks PA-Series is definitely worth the investment a company is paying to use it."
"A valuable feature that we can consider is the deployment time, which is significantly reduced. It is almost 90% faster compared to other solutions."
"The product's initial setup process was simple."
"The documentation is great."
"This is a capable appliance and the standard features work well for us."
"The Zyxel Unified Security Gateway solution is stable and does its job effectively."
"The most valuable features of the solution stem from web filtering, malware protection, and antivirus."
"The cost is very low."
"The solution can scale well."
 

Cons

"I encountered a slight issue with the application portal, which was not functioning correctly."
"There seem to be some issues with TAC (Technical Assistance Center) or Palo Alto support. Anytime you open a case, a level one engineer joins, and then you have to escalate it to level two or three. The support system has changed in the past few years, and that's something they need to look into."
"Licenses are too costly. As I compare with Check Point or other OEM, the licenses are too much more costly and they should work on bundled licenses."
"The product's high prices are an area of concern where improvements are required."
"The product's gateway services can be improved."
"The UI definitely needs work. In my opinion, the UI could be simpler and more user-friendly for the average user."
"There is room for improvement in Palo Alto Networks PA-Series in the areas where they can minimize applications and implement features that can be useful for us."
"There are constant updates for the operating system. It is a nice thing also, but it has its own disadvantages. Continuous updates are there. The users face issues like, how often do I need to update that? Within a period of five months, I'm updating it two or three times. It gives them a feeling that they are not confident about their product and have to update it so frequently."
"Although manageable, the user interface is a little bit slow and could be improved. The advanced UI allows me to do whatever I want, but this is where the issue of speed exists."
"Sometimes it reboots when you least expect it, and that's the main issue."
"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 integration capability is quite challenging. The system is very complicated, and many features are hidden."
"The product has some scalability and data management issues where improvements are required."
 

Pricing and Cost Advice

"The pricing is a bit on the higher side."
"This product has an affordable and reasonable price point."
"The pricing is fair."
"With Palo Alto, even when you enable all the modules, it still provides the exact throughput they advertise."
"The product is expensive."
"From my perspective, managing the price is important, especially because we're a small business. For larger organizations like Barclays, we provide our requirements to the client, and they place the order on BigFix. It's their responsibility to consider their budget and make decisions accordingly. We appreciate the features we get, but the cost-sharing still depends on the client."
