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.

Has provided built-in VPN tools and reporting features that streamline remote access and monitoring tasks
We do an outside-sourced threat prevention regarding the Threat Prevention features. I haven't run into areas that could be improved or cons versus pros for Untangle NG Firewall. I haven't done anything too advanced when it comes to the filtering, so I'm not sure what can be improved or added. I haven't dug into the advanced features, but I think some of the advanced capabilities are probably where it lacks a little bit, with the filtering and firewall rules. These areas could be improved to make it a nine out of 10 or a 10 out of 10 for overall rating.

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

"First and foremost, Fortinet FortiGate is a security device that can optimize security on the networks of a company and actually protects the company from attacks from outside."
"Customers want to load balance more than six internet lines, and FortiGate is the only solution that can accomplish this."
"The solution is easy to configure and maintain remotely."
"Integrated management would probably be the most valuable feature."
"With the application and web filters, we were able to block social network websites and any other websites that could lead staff being less productive."
"It offers web filtering capabilities at a more affordable price compared to other solutions like PSMs or NETGEAR."
"Fortinet FortiGate has many functions, and it is one of the best next-generation firewalls with an affordable cost than other vendors."
"I prefer FortiGate because it has a lot of other solutions embedded within it and is the easiest for our technicians to operate."
"The most valuable features are IPS, MAPI, NAT, and VPN."
"We have had incredibly good results with all of its features."
"The interface is very good."
"The flexibility to grow, the user-friendliness of the interface, and the common center facility are the advantages of Untangle NG Firewall."
"The solution's most valuable feature is the content filtering."
"The product’s most valuable features are endpoint protection management, load balancing, and connectivity with Active Directory."
"Web filtering is very reliable."
"We find the web filter very valuable."
"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 cost is very low."
"The most valuable features of the solution stem from web filtering, malware protection, and antivirus."
"This is a capable appliance and the standard features work well for us."
"The solution can scale well."
 

Cons

"Fortinet Fortigate could benefit by simplifying some of their processes."
"Regarding stability, I have experienced performance issues with Fortinet FortiGate. Sometimes it does not work correctly in certain situations, such as DNS or URL categories, where it might block incorrectly."
"Improvements could be made when companies expand and need better equipment and more licenses."
"I would like to have SD-WAN as a part of the Next Generation Firewall. It would enhance high availability."
"The anti-malware engine could use an upgrade."
"It should have a better pricing plan. It is too expensive."
"Its load balancing feature could be easy to configure."
"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."
"The ability to setup a DDNS for each WAN independently would be a very handy feature."
"The local technical support does not understand the product very well."
"On their low-end appliance, they could have more memory and the largest storage space. The low-end appliance comes with a too-small hard drive, and it could use a little extra room. It only comes with about 4 gigs or 8 gigs of memory, and the hardware space is only 40 gigs, which is really small."
"It would be much easier if there was a mobile app."
"Web-filtering policies could be improved."
"I haven't dug into the advanced features, but I think some of the advanced capabilities are probably where it lacks a little bit, with the filtering and firewall rules."
"I do not know if I have seen any return on investment. It might be a little expensive if I need to make an external firewall or at my sites like DNS and web zones."
"The product needs to improve its mobile application."
"I have never seen it in any company that I've worked with before, and I would advise other companies not to buy it."
"Although manageable, the user interface is a little bit slow and could be improved."
"The product has some scalability and data management issues where improvements are required."
"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."
 

Pricing and Cost Advice

"Its price is good."
"If you compare the price of Fortinet FortiGate IPS to other firewalls, Check Point is priced very high followed by Palo Alto and Sophos. Fortinet FortiGate IPS price is more reasonable."
"The price of FortiGate is comparable to that of most other firewall solutions and is more affordable than Cisco."
"I would rate the pricing a six out of ten, where one is cheap and ten is expensive."
"For our organization, the licensing costs are approximately $7,000 per year."
"We pay for the solution annually."
"It has a competitive price."
"The solution requires a license annually, it is not a user license, you can have as many users as your want. I must renew the license regularly per device."
"We pay $350 USD per year for the solution. There are no additional costs. As long as you're not using a physical appliance, that's all you need."
"Usually, it's about $350 a year for 12 users, and it's about $600 for 50 users. It's very reasonable as compared to the others. One of the reasons is that they're all open-source. You just buy their appliance and put it in until it dies. Because it's run under open platforms, mine seems to always work on older equipment. I've taken old equipment and put a new hard disk in it. I have taken about nine-year-old computers and put their operating system on them, and ran them like a champ. The only thing that changed was the hard drive because I don't trust a hard drive that's more than three to four years old."
"The setup cost is about $2000 to $3000 per year."
"It is not expensive. The best part is that it is based on the pay-per-use kind of scenario. An increase or decrease in the number of people doesn't make any difference. We are really happy about using this particular scenario."
"The tool's pricing is moderate, and licensing costs are yearly."
"It is not expensive. It is cheaper than Fortinet."
"The solution is fairly priced."
"This is not an expensive product. It is affordable and there are different packages available depending on the features that you need, or the sector that you are in."
"This gateway is pretty cheap."
"The price of Zyxel Unified Security Gateway is good compared to other similar products in the market."
