Efficient, user-friendly, and affordable
In the past, NSS Labs was utilized to test files and verify the numbers and datasheets. It would be beneficial to have an organization or testing lab that can verify the numbers in our datasheets since changes are frequently made, which can be inconvenient for review. For instance, when comparing different competitors such as Forcepoint, Palo Alto, and Check Point, the throughput or numbers in the datasheet may be lower than the actual numbers. Conversely, Fortinet typically reports very high numbers, but they cannot be replicated in the real world. Therefore, it would be advantageous for them to partner with a neutral testing organization such as NSS Labs to validate these numbers, thus providing more credibility and comfort to everyone regarding the accuracy of the datasheets. For the migration, everyone has a firewall in use and I am selling Fortinet. Typically, I am replacing another firewall. Previously, there was a tool available to convert configurations from one firewall, such as Palo Alto, to Fortinet, but this tool is no longer free. If it could be made free again, it would be very beneficial. This tool shows a lot of promise and is very good. Making it free would help many companies deliver their products in a more efficient and integrated way. It would also be more valuable to include the tool with the firewall package or license instead of having to pay extra for it. Paying extra puts more pressure on small companies to deliver the firewall and complete the configuration, especially if they have hundreds or thousands of policies. It's very painful to move through these policies line by line. The stability has room for improvement. When it comes to Secure SD-WAN, everything is fine. They are going the right way. SD-WAN is very promising. They can provide the SD-WAN solution separately, but they will not take this approach because even the smallest firewall can support the features, so there is no need to have a separate service or appliance. They are following the right steps, and there is nothing to be improved. Feature-wise, I'm really satisfied with the new release, and the features they have added. For now, it's fine.

One of the best tools for the prevention of evasive threats
There is a feature called granular application controls, which I liked. Instead of relying on ports and IP addresses, they use AMP ID. This kind of solution is very good. Another valuable feature is the prevention of evasive threats, which is one of the best tools I've encountered. SSL decryption and app ID-based SSL decryption are also impressive, along with the integration with user ID. Identity-based policies ensuring only authorized users can access specific resources are excellent features. Normally, there is something called SIM or SCIM in IDA IDM, but this feature is provided on the box, which is exemplary.

Provides inline protection with a unified view and anti-spyware capabilities
I would rate Palo Alto Networks NG Firewalls ten out of ten because it is the best. Our disaster recovery site utilizes Palo Alto Networks Next-Generation Firewalls. We are also in the process of upgrading the firewalls at our 365 sites in Pakistan to Palo Alto Networks firewalls. While budget firewalls may advertise comparable features, they often fall short of effectively detecting viruses, threats, and ransomware. In contrast, Palo Alto Networks NG Firewalls, combined with Cortex XDR, provide comprehensive threat intelligence and detection capabilities, ensuring superior security coverage. I recommend conducting a proof of concept before selecting a firewall. This will allow you to evaluate different options and determine which best suits your needs. While Palo Alto offers robust firewall solutions, it's essential to compare them with other vendors to ensure you make an informed decision.

Quotes from Members

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

Pros

"We can use our devices to check all of the perimeters. It secures email websites."
"The most important features with FortiGate are the web filter and application controls. We can control our internet usage and use the web filter for application purposes."
"FortiGate has led to a reduction in our security budget."
"The features that prevent internet connections, the filtering are the most valuable because we did not have any internet protection before."
"The VPN is the most valuable feature."
"The most valuable feature of FortiGate is FortiView which provides proactive monitoring."
"We use the FortiGate Sandbox to detect zero-day vulnerabilities, such as anomalies or malware, that are unknown and have not yet been discovered."
"The interface is very good."
"The IPS system is the best in the field."
"Palo Alto firewalls are scalable enough. We have about 110 employees in our company, and we are about to expand to 130."
"It's easy to configure."
"As long as the solution is kept updated, it's pretty stable."
"It is a stable solution."
"One of the most valuable features is Palo Alto's firewall management. We find it easier to manage the firewall centrally."
"I like the tool's WildFire feature."
"The most valuable feature of Palo Alto Networks K2-Series is the performance which is above their competitors. The throughput they have delivered is good. When we used other solutions they failed the deployment when we were using different rules. They have a theory perform performance light and performance degradation. However, Palo Alto Networks K2-Series never fails in that scenario."
"The structure is much faster and more sophisticated than Cisco."
"Palo Alto Networks NG Firewalls' single-path architecture offers a valuable feature, ensuring stable performance for our customers."
"The unified platform provided is very important to us as it allows us to manage all traffic and ensure security without using separate tools. It has AI and ML capabilities, which work well for real-time attack prevention."
"The most valuable feature is the ability to deeply analyze the connection or connection type."
"The DNS sync code in your filtering is the most valuable feature of the Palo Alto Networks NG Firewalls."
"It is very scalable."
"The scalability is very good."
"Compared to other firewalls from Check Point, Fortinet, and Cisco, for example, Palo Alto Networks NG Firewalls use the most advanced techniques. They have sandbox integration and others in the orchestrator. Palo Alto's security features are at a higher level than those of the competitors at the moment."
 

Cons

"There are a lot of bugs I have found in the solution and it is difficult to upgrade. These areas need improvement."
"The solution could be more user friendly."
"It does not have key authentication for admin access."
"It should come integrated or have its own type of network monitor tool in a module. There should just be one package, and you are good to go."
"Fortinet FortiGate could improve by adding FortiAnalyzer to its solution, we should not have to use another solution. FortiAnalyzer can provide more detailed information."
"We would like to see an upgrade to the VPN feature, we are using the VPN from outside of our office and there is a limitation to 10 connections, more connections would be suitable."
"The solution could be improved by addressing limited local reporting. It requires obtaining the FortiAnalyzer for proper visibility because you can't do much from a reporting perspective with just the firewall alone."
"The license renewal process, annual renewal price, and the web application firewall features should be improved."
"I would like to see the threat intelligence capability integrated with other vendors such as Cisco and Forcepoint."
"The solution needs a series of OS changes."
"The licensing cost is a typical complaint with many clients. The solution is expensive."
"There are a lot of bugs in this solution."
"Sometimes there are interactions with support or the provider that are not ideal."
"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."
"It would be nice if it could easily be integrated with Elasticsearch or Nagios."
"Higher levels of support are excellent but new users may need additional options."
"The tech support was once great, but now it is poor. The tech support has gone south. It is really difficult. I had a Priority 1 case last a week in their queue, and after multiple complaints, I finally got somebody to take the case. These are things that are unacceptable in the business world. They could train their employees better."
"Palo Alto's support could be improved."
"Overall it is good. It is reliable and easy to understand. However, the monitoring feature could be improved."
"I would like to see some Machine Learning because I have observed new types of attacks that are able to bypass existing security rules."
"I wish that the Palos had better system logging for the hardware itself."
"We have a lot of the older firewall models, i.e., the PA-220. It seems that with newer operating systems the PA-220 is becoming slower than when I first bought it. It is not really an issue for users who are passing traffic through the firewall, but more from the management access of it."
"The VPN has room for improvement."
"There is a web-based GUI to do management, but you need to know how the machine or firewall operates. There are hundreds of different menus and options. I have used other firewalls before. Just implementing or designing a policy with Palo Alto, if you want a certain port to be open to different IP addresses, then that could take 20 to 25 clicks. That is just testing it out. It is quite complex to do. Whereas, with other places, you tell it, "Okay, I want this specific port open and this IP address to have access to it." That was it. However, not with Palo Alto, which is definitely more complex."
 

Pricing and Cost Advice

"Fortinet costs are 25% lower than the high-cost provider. There is an equipment cost and a recurring monthly cost for licenses and technical support."
"For our organization, the licensing costs are approximately $7,000 per year."
"The price is fine."
"Our licensing costs are on a yearly basis."
"Fortinet FortiGate allows you to purchase licenses for hardware and software."
"Fortinet FortiGate's price can be reduced."
"The price of Fortinet FortiGate is reasonable."
"It is an inexpensive solution."
"This product is designed for large companies. The price would not be suitable for a small or medium size company."
"We are on an annual license to use Palo Alto Networks K2-Series."
"If you compare K2-Series' quality with its price, I think it is reasonable."
"It is an expensive solution."
"Pricing is a sensitive issue because the cost is high in this market."
"The pricing is expensive."
"This solution is expensive compared to other, similar products."
"It would be nice if they lowered their prices for small businesses."
"The tool's pricing is similar to that of Cisco. It's a security appliance; the cost depends on your network topology and specific requirements. The suitability of NG firewalls should be chosen based on your network and what you need. If a colleague from a different company asked for the cheapest and fastest firewall, I suggest they consider options like Sophos. Sophos took over Cyberoam, which was previously a leader in NG firewalls"
"It has a yearly subscription."
"Cost-wise, I don't see much difference in network-related costs, but this is a premium-grade firewall. There is a cost involved, and you must pay for that to get the most out of it. Its licensing costs are straightforward. There aren't any hidden costs."
"Cheap and faster are the opposite sides of security. Security inspections have some technical and money costs. If you just purchase some cheap, fast firewalls, then you will lose a lot of the security features and fraud protection capabilities."
"The solution is worth the price, as it can be utilized without the need for high-processing CPUs and resources, thus saving us overall."
"Active/Passive mode is very redundant, but they require you to buy all the associated licensing for both firewalls, which is kind of a waste of money because you are really only using the services on one firewall at a time."
"Its price should be improved."
"The pricing is very high."

In the best tradition of these questions, Feature-wise both are quite similar, but each has things it's better at, it kind of depends what you value most. PA is good at app control, web filtering and such like, they have always been top of the pile there. The GUI is very good, and their product is very user-focused. Fortinet is good for scalability and predictable high throughput (ASICs in the...
