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.

Is stable and has a user-friendly dashboard and a good interface
We installed Hillstone T-Series after a ransomware attack. The dashboard and user interface are very good We cannot secure a specific IP class with this firewall. Another loophole with Hillstone T-Series is that when we connect through WiFi and turn our hot spot on, all who connect through the…

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.

Quotes from Members

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

Pros

"FortiGate has a strong security topic which allows all of the Fortinet devices to communicate and share information which makes their security more powerful."
"FortiGate firewalls are user-friendly, and I like the security profiling features."
"Overall, the pricing of the solution is very good. The product offers good value."
"The stability and scalability of this solution are satisfactory. Its SD-WAN, VPN, and URL filtering features are very useful."
"The most valuable feature of Fortinet FortiGate is load balancing. It can provide central management and VPNA. Additionally, it has enhanced our security environment."
"The stability of the solution is excellent, as it is with other Fortinet products."
"Consolidated our network environment at all locations, but mainly at our datacenter."
"I'm looking forward to FortiGate's dashboard features, insights, application oversight, and monitoring, which could help us significantly."
"The only firewall able to monitor traffic from a CCTV network. Can detect unauthorized devices plugged into the network, which standard firewalls can't do."
"We installed Hillstone T-Series after a ransomware attack. The dashboard and user interface are very good."
"It has been stable so far."
"The scalability of the product is quite high."
"The most valuable feature of Palo Alto Networks K2-Series is its management abilities. Additionally, the updates are very good."
"Overall product rating: Nine out of ten."
"One of the most valuable features is Palo Alto's firewall management. We find it easier to manage the firewall centrally."
"The IPS system is the best in the field."
"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."
"Palo Alto has a unique solution for DNS security, which is very good."
"Prevention of evasive threats is one of the best tools I've encountered."
 

Cons

"At this moment, we believe that Fortinet FortiGate should be improved by injecting more AI because the kind of threats we are seeing are more ransomware threats. Fortinet FortiGate is able to ensure these threats do not enter, but we would prefer to see more proactive alerting mechanisms come out."
"They could improve the response time and quality of support."
"The non-error conserve mode has room for improvement."
"I don't really have anything negative to say as far as Fortinet firewalls are concerned. If anything, they can support a user a little bit better. They can stop being so time-sensitive about how much time the support call has taken, and they can help you do it yourself."
"I could not configure sFlow from the FortiGate graphical user interface. I realized that the sFlow configuration is available only from the CLI, and discovered that sFlow is not supported on virtual interfaces, such as VDOM links, IPsec, or GRE."
"A sandbox would be good in order to be able to inspect the emails containing spam and be able to validate the emails that contain malware, prior to delivering to the customer."
"Fortinet FortiGate could improve by adding enhancements to FortiMail, FortiSOAR, and FortiDeceptor."
"I would like to see a more intuitive dashboard."
"Licensing is not cheap."
"They have a very good technical support team, but I think there are some communication issues due to language differences."
"Another loophole with Hillstone T-Series is that when we connect through WiFi and turn our hot spot on, all who connect through the hotspot get all the functions, and the security does not work."
"The password function of the solution could be improved. Additionally, some of the processes take too long to complete."
"It is recommended that the Palo Alto Networks K2-Series be implemented step by step for the Panorama. Sometimes we can't overwrite the configurations because it fails."
"The product should get frequent updates allowing us to add new signatures."
"The ease of management and configuration should be improved."
"Threat prevention could use improvement. Not just in malware exploits and C2 traffic; enhancing web traffic protection would be a great upgrade."
"Palo Alto doesn't have extended visibility to the end point in their firewalls."
"I'd like to see more data protection on the system."
"In the past, we've had trouble with Palo Alto's application filtering not getting it right. I would not be recommending layer 7 application filtering yet."
 

Pricing and Cost Advice

"It's an expensive solution."
"The price of FortiGate is comparable to that of most other firewall solutions and is more affordable than Cisco."
"The price is fair compared to the other competitors."
"The price of FortiGate support is too expensive."
"The price of Fortinet FortiGate is the lowest in the market."
"Pricing is good. They offer a lot of things, the most important is the support. Every time you upgrade your license, you also get insurance for the equipment. If you have any problem with equipment, they send in new equipment."
"It has been two years. I don't remember the actual price, but it was affordable. We buy the boxes and then use the license for three years."
"Each feature costs money, so it is important to study your needs."
"We got a much cheaper price than that provided by Fortinet right now."
"On a scale from one to ten, with one being low and ten being high price, I would rate the price of Hillstone T-Series at three. There are no additional costs other than renewal costs."
"Products by the leader in the field are justifiably a bit more expensive compared to other vendors."
"Palo Alto Networks K2-Series is an expensive solution, the price could be reduced. They are more expensive than some of their competitors."
"The price of this solution is too high."
"The pricing is expensive."
"It would be nice if they lowered their prices for small businesses."
"If you compare K2-Series' quality with its price, I think it is reasonable."
"It is an expensive solution."
"This product is designed for large companies. The price would not be suitable for a small or medium size company."
