Strong threat prevention has reduced phishing and malware while I monitor traffic in depth
Palo Alto Networks NG Firewalls offers application and user awareness, which allow me to control traffic based on threats. The product includes threat prevention, advanced threat prevention, and deep packet inspection that really helps prevent issues in our network. Deep packet inspection inspects full traffic content, even inside applications and encrypted sessions. Deep packet inspection makes a very practical difference day to day because it lets me see and control what is actually inside the traffic, not just the open port or IP. I have real visibility of which application is running instead of just seeing HTTPS. Palo Alto Networks NG Firewalls WildFire sandboxing is really good at detecting and blocking zero-day malware automatically, along with its GlobalProtect and DNS security features. Using Palo Alto Networks NG Firewalls positively impacts my organization by providing strong security, better visibility, faster response, and simplified operations. After deploying Palo Alto Networks NG Firewalls in our network, it blocks malicious traffic and prevents compromises that occurred before Palo Alto Networks NG Firewalls. I can now block outside IPs to prevent issues. After Palo Alto Networks NG Firewalls installation, I reduced 60 to 70 percent of malware and phishing attacks. Its threat prevention and DNS security features detect these attacks, block malicious domains, and reduce manual efforts for the security team.

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 NGFW’s unified platform has helped our customers eliminate security holes. With a unified platform, customers can deploy the NG Firewall both in the data center edge, inside the data center, and in the product/public cloud environments. They have the same user interfaces and platform, so they can be maintained by a single unified platform called Panorama. Customers can use Palo Alto Network NG Firewalls in all the places where they need to protect their environments. This helps to decrease security holes."
"We have found the DPI ability to understand web applications and build access rules on web application categories first to be a great feature."
"I like that Palo Alto does a good job of keeping the firewall updated with the latest threat signatures."
"The initial setup was very easy."
"This solution has really helped the technical engineers to deliver the implementation faster than before."
"We have complete visibility through the logs and the alerting."
"GlobalProtect and App-ID features are very good."
"It is an extremely powerful solution as it provides visibility into all the network traffic, and offers a range of actions such as blocking websites or graphics, as well as load balancing. It's a great tool."
"The solution can scale well."
"The most valuable features of the solution stem from web filtering, malware protection, and antivirus."
"The Zyxel Unified Security Gateway solution is stable and does its job effectively."
"This is a capable appliance and the standard features work well for us."
"The cost is very low."
 

Cons

"There has been a recent change in the graphical interface. For the monitoring part, they could have a better UI."
"This solution cannot be implemented on-premises; it's only a cloud solution. The price is high as well."
"The integration with AI needs improvement."
"Palo Alto claims their NG Firewalls are highly customizable, but this isn't always true."
"The scalability is not so good because if you want to upgrade, you have to change the service completely."
"The price is high and has room for improvement."
"There is a tradeoff between security and network performance, as security is always top-notch, but performance can sometimes lag and has room for improvement."
"Palo Alto should improve their support. It's sometimes difficult to get the right technician or engineer to fix the problem as soon as possible."
"I have never seen it in any company that I've worked with before, and I would advise other companies not to buy it."
"Sometimes it reboots when you least expect it, and that's the main issue."
"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."
"The product has some scalability and data management issues where improvements are required."
"The integration capability is quite challenging. The system is very complicated, and many features are hidden."
 

Pricing and Cost Advice

"It's cheaper to replace the equipment every three years than to upgrade. We have done two refreshes of their appliances. What I have seen is that the initial hardware cost is low, but you need a subscription and you need maintenance plans. After every three years, if you're trying to renew your maintenance or subscription, that can be very costly. It's cheaper to just get a newer solution with a three-year subscription and maintenance. It's cheaper to replace your hardware completely with a new subscription plan and a new maintenance plan than to renew the maintenance subscription on existing hardware."
"The price is high."
"Pricing is yearly, but it depends. You could pay on a yearly basis, or every three years. If you want to add a device or two, there would be an additional cost. Also, if you want to do an assessment, or other similar add-on, you have to pay accordingly for the additional service."
"Its price is quite high but is justified for the features and capabilities provided, although I would prefer a lower price."
"If the cost is your main priority, Palo Alto would be a bit high. However, if you are ready to hear about return of investment, then I would convince you to go for Palo Alto."
"Definitely look into a multi-year license, as opposed to a single-year. That will definitely be more beneficial in terms of cost... 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."
"You get what you pay for."
"This solution is quite expensive."
"This gateway is pretty cheap."
"The price of Zyxel Unified Security Gateway is good compared to other similar products in the market."
