Unified security and sd-wan have improved uptime and cut wan costs for multi-site branches
Users report stability issues in certain versions, which requires regular updates. Real-world attacks have also highlighted the need for urgent patching of vulnerabilities.Fortinet FortiGate, while a powerful and feature-rich web firewall, could improve in areas like firmware stability, documentation, and ease of use. The learning curve can be steep for some users. For beginners, support quality can vary, and frequent updates with occasional vulnerabilities call for careful patch management. However, once Fortinet FortiGate is configured, it remains highly reliable and efficient. Customer support needs improvement, as I find it very slow, with reports from other users reflecting that customer support is inadequate.

Faced hardware limitations and setup challenges but have improved network protection over time
I spent much time finding exact firmware on Aruba which was working with these guns, but it is not optimal because it is not the latest version, so there could be potential security problems. We decided to replace those access points with another one. I personally have trouble because I don't know the exact life cycle of Fortinet FortiGate-VM boxes. I don't know if the life of boxes is five years or something else; we moved from our previous company, which sold us to other companies. Before 10 years, we had a special department that took care of core networks, including firewalls. After that, this responsibility fell to me and my colleague. It is not easy to set up these Fortinet FortiGate-VM boxes properly because we didn't have previous experience with this kind of solution. At first, we set up only a few rules that were not secure enough, and over a couple of years, we improved the settings and security of these Fortinet FortiGate-VM boxes. Currently, I have one Fortinet FortiGate-VM that needs to be replaced next year, and this box is not so powerful, so I need to redirect some traffic to another Fortinet FortiGate-VM. It is stable, but because the CPU processor of this box is not powerful, I need to redirect some traffic to another box. In the future, I need to choose a higher-level box to prevent potential troubles with the power of this box.

Quotes from Members

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

Pros

"It's simple to operate and use."
"The next-generation firewall is great."
"Fortinet FortiGate has saved me both money and time."
"We have a lot of experience with this solution and haven't had any issues; for repairs, the RMA process is also good, and we don't have any issues with the interface, customization, or integration, as this solution works well."
"Has a very user-friendly interface and doesn't require any prior knowledge."
"It has improved our organization with control data."
"The security fabric is excellent."
"On a scale of one to ten, I rate this solution 10 out of 10."
"The solution is highly stable."
"With this solution, you can apply the zero trust concept in place with role-based access to the internet, URL filtering works well and is flexible, and with integration with other security solutions you can quickly respond to incidents so fewer security incidents appear and you can respond more quickly."
"The most valuable features of Fortinet FortiGate include web filtering and application category functionality; the application category allows web filtering based on categories, which is one of the strengths of the Fortinet FortiGate firewall."
"The most valuable features we have found to be the VPN, ease of use, and overall simplicity."
"The most valuable feature is the WAN optimization."
"What I appreciate the most about Fortinet FortiGate-VM is that it is not much different than hardware appliances."
"I would recommend stopping waiting to use Fortinet Fortigate; it's really a great solution and their support is very good."
"The product is quite user-friendly so we didn't have a lot of issues that needed to be addressed."
"We installed Hillstone T-Series after a ransomware attack. The dashboard and user interface are very good."
"It has been stable so far."
"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 found some limitations with Fortinet FortiGate, and we are satisfied with Hillstone T-Series right now."
"Hillstone supports IOT setup and detecting intrusions from IOT or CCTV connectivity, and with this solution, we can also detect unauthorized devices plugged into the CCTV network and sound the alarm to the administrator."
 

Cons

"In an incident, after a restart, Fortinet FortiGate did not connect to FortiGuard servers. Due to that reason, on the customer end, all websites got blocked. I don't know why this happened. The firewall of a bank in Sri Lanka rebooted yesterday, and after that, FortiGuard servers did not connect properly, blocking all customer environment websites."
"The solution could improve by being more secure."
"The integration with third-party tools may be something that they should work on."
"Their technical support could be improved a little bit in terms of responsiveness."
"I have faced challenges related to support, as I have encountered issues where support engineers are not aligned within the time frame, and sometimes they request multiple logs unnecessarily, causing delays and leaving a bad impression on my end users."
"FortGate's IPS reporting could be made better by giving more details regarding the source and destination of network traffic when it comes to the overview section."
"The reporting in Fortinet FortiGate could improve. Customers are having to purchase additional reporting components, and in Fortinet FortiGate you have to use additional tools to have the features needed."
"Fortinet FortiGate can improve performance. There was a huge challenge in terms of CPU and memory where the IPS engine would keep triggering. There were random spikes of overutilization in the CPU and memory resources. They have to work on CPU and memory stability considering these IPS engines. A few versions were very unstable."
"They should keep us up to date about the latest version. Currently, we have to go looking for the latest version."
"We haven't attempted to scale the solution just yet. If we want to scale this solution we may have to look at other models."
"Improvements are needed for the responsive UI and JIT traffic reporting."
"Pricing should be more competitive, it's expensive."
"There should be more options to use lower-end models in a high availability configuration."
"They should keep us up to date about the latest version. That's the biggest thing. Currently, we have to go looking for the latest version. We should get notified about what's going on with the versions. I would like to see easier dual-factor authentication."
"It should have the SD-WAN feature. This would increase the number of features that are available in the box."
"The price is sometimes very expensive.​"
"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."
"They have a very good technical support team, but I think there are some communication issues due to language differences."
"Licensing is not cheap, but there are customers who will buy because they understand that this has a cost involved and they will cater their budget for that."
 

Pricing and Cost Advice

"My experience with the pricing, setup cost, and licensing for Fortinet FortiGate is quite good. I don't have a public site, such as in Azure, where I can see the pricing. I always have to go through the distributor, and that could take some time to get the real price for each appliance."
"Fortinet FortiGate allows you to purchase licenses for hardware and software."
"Fortinet is competitive price-wise."
"The Indian market is different than the European and American markets. When you compare they need to be a bit more aggressive on pricing."
"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."
"I rate the pricing an eight and a half on a scale of one to ten, where one is low, and ten is high."
"The price is highly competitive when compared to other brands that offer similar functionality."
"It's one of the more expensive brands. The 100 series costs around $4,000. They are similar in pricing to what you might get from Cisco solutions and probably other similar ones. They're not more expensive than other similar solutions, but they're certainly not cheaper either."
"Of all the firewalls that we compared, FortiGate is the cheapest and most affordable, so we are satisfied with the pricing."
"The pricing and licensing are not as expensive as its competitors."
"At present, the SD-WAN licenses are on an annual basis."
"For large enterprises, price is not a problem because they need that solution. However, in the Philippine market, many of our clients are still small to medium businesses, so the price can be challenging. The license for Fortinet FortiGate-VM costs 100K to 150K Philippine pesos per year for VM1 or VM2."
"There is no additional cost. Once you get the licensing fee, you're good."
"There are no additional costs beyond the standard fee."
"This solution is very expensive."
"Our license is yearly, but we're thinking of going monthly. I think it's somewhere around 100,000 for VM04. Nowadays, everyone wants to be a hacker, so we believe in security. That's why we also have third-party people that we involve to make sure that we're secure. I don't think the costs are too bad. You still want to get advice from people who worked in security for many years, so you add a third party. The third party also said they would give their share like 100K, or 200K or something like that, so I don't think it's too expensive for security. I think it just adds more trust."
"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."
"We got a much cheaper price than that provided by Fortinet right now."
