Network Security Engineer at Arrow PC Network Pvt Ltd
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.

Enhanced threat detection with integrated security features and good support
We are using application firewalling, WAF, and SD-WAN. The capabilities are mostly within the box. For example, you will get web application firewall WAF as part and parcel of this. SD-WAN is also bundled. It integrates with their SIEM and SOAR solutions very nicely. Lastly, the pricing point is very cost-efficient as well.
Gary-Downey - PeerSpot reviewer
Director of Information Technology at a consultancy with 11-50 employees
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.

Quotes from Members

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

Pros

"It's super reliable, I don't think I've ever had a reliability issue with it."
"The SD-WAN function is very developed. It has SD-WAN functionality with security features in one device. We can manage from one single console SD-WAN and the security policy."
"Fortinet scores very high against security threats when you compare it with Check Point and Palo Alto."
"Fortinet FortiGate helps improve my organization since it's quick and easy to install, and we don't have to call support frequently."
"The most valuable feature of this solution is the analytics."
"I like the security that Fortigate offers; it has great URL filtering with a next-generation firewall that can do internet routing, plus give us advanced layer seven application control."
"The most valuable features are simplicity, management, and that it's constantly evolving."
"The features that I have found most valuable are the SD-WAN and their IP4 policy."
"SSL VPN is the best feature."
"The most valuable features are the WAN optimization, the internet access gateway (IAG), and the central console, which allows us to implement on their firewall."
"You might try Sangfor if you are on a tight budget. The price is affordable, and Sangfor offers a lot of features. We don't have any complaints about Sangfor."
"We are Sangfor Gold partners and I'd recommend this solution for the SMB market, as it is cost-effective and reliable."
"Sangfor's tech features and technologies are more powerful than those of the other solution providers in terms of security. They also have big solutions in terms of cybersecurity."
"The level of support provided to local companies is good. They transform their application control and other settings according to that country."
"Sangfor has the best capabilities for securing connections, securing web browsers, securing servers, and general threat protection."
"We use Sangfor NGAF primarily for security, which has helped save our files from being encrypted by ransomware."
"They have a command center that makes it easy to log into and see all of your appliances nationwide."
"The Untangle firewall is a software firewall, so it runs on generic hardware. We found that was probably the best feature, and it's why we chose it when we started using it three years ago."
"The threat prevention features of Untangle NG Firewall have helped my network security management, and I find them very good."
"Untangle NG Firewall is something that I recommend, although we have only tried the software version."
"Its ease of use, variety of available features, and low pricing have enabled us to improve the security for a lot of our very small business clients at a price that they are happy to pay for."
"Untangle is a much better buy for the money than SonicWall."
"​It is very easy to deploy and monitor. ​"
"All features are useful. We are using premium features such as bandwidth sharing, failover, web filters, SSL controls, antivirus, and VPN. We use these features to the fullest. These features are available in the paid firewall license, not the free one."
 

Cons

"Fortinet FortiGate should improve the VPN tokens."
"The renewal cost is much higher than other firewalls. It is not reasonable."
"We can't identify which users are causing challenges when we have issues."
"Technical support is a little slow and needs to be improved."
"The pricing could be reduced or include the first year warranty."
"The customization is a little bit difficult because we have to customize everything."
"I think that the infrastructure for the VPN could be improved. The way that it is bundled also made it difficult to use and sell as it is too expensive."
"The feedback that I have received is that the performance could be better, and the user experience is not as good compared to a previous solution we used. It could be more user-friendly. Of course, it still works fine for our operations."
"I would be happy if Sangfor developed a firewall designed specifically for home use, as well as for small businesses such as clinics and so on. A household version of the Sangfor firewall for your personal computer or laptop would be ideal, in my opinion."
"The web interface needs to be improved, making it more user-friendly."
"The firewall system needs gradual improvements because there are more threats and challenges in the world every day."
"The GUI needs to be improved, lacks logic in some areas."
"Sangfor NGAF could improve by refining its application control policies, especially in addressing challenges with certain types of applications."
"However, the maintenance cost can be a bit high."
"The web interface needs to be improved, making it more user-friendly."
"We have deployed many firewalls and have faced two or three faulty devices that we have to replace over a year because their power supply was faulty."
"The product needs to have a better support group for its online support, specifically for its help desk."
"If you have a site that has more than 50 devices on it, then Untangle quickly becomes cost prohibitive in comparison to several other competitors."
"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 pricing should be reduced because it is expensive."
"The local technical support does not understand the product very well."
"The management console for partners is a bit tricky (buggy)."
"Web-filtering policies could be improved."
"The product needs to improve its mobile application."
 

Pricing and Cost Advice

"I think the price of Fortinet FortiGate is very reasonable."
"We are currently evaluating a Palo Alto solution, and the pricing could be a reason for going for Palo Alto."
"We pay for the solution annually."
"The price of Fortinet FortiGate is reasonable for an SME."
"Fortinet is competitive price-wise."
"If the price of the license in Fortinet FortiGate was less expensive it would be better."
"It's expensive, but compared to the competition it's okay."
"In the Asian economy in which we operate, FortiGate is expensive."
"I rate the product price as one on a scale of one to ten, where one is low price and ten is high price."
"The license of Sangfor NGAF can be purchased at different interval lengths, such as annually or three years. They offer a range of packages to choose from, such as combo or hybrid packages. We are using the complete solution package which includes IM, NGF and SSL VPN, and WAF."
"The price could be more competitive."
"Sangfor is cheaper than competing vendors."
"Sangfor NGAF is a cheaply priced product, especially if I consider the previous product that was used in my company."
"It is one of the cheapest tools in the market."
"It costs about 8 to 10 thousand dollars per year for 500 users, standard licensing fees included."
"Sangfor NGAF price is reasonable and there is an annual license. However, the maintenance cost can be a bit high."
"The solution is fairly priced."
"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."
"It is not expensive. It is cheaper than Fortinet."
"Untangle is open-source software. So, you can get it for free. That has been a benefit, especially for the residential users because it is free. The license costs start at $25 a month for some additional features, including higher tiers of security intrusion prevention. The free version comes with intrusion detection, and then the license version has intrusion prevention. It also has some additional things for active directory connectors, etc. It starts at $25 a month to cover 12 devices. Then it goes up from $25 to $50 a month for 12 to 25 devices. That's where it really doesn't scale out per site. If you have a site that has more than 50 devices on it, then Untangle quickly becomes cost prohibitive in comparison to several other competitors."
"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 pricing model is better than with SonicWall."
"On a scale from one to ten, where one is cheap and ten is expensive, I rate the solution's pricing an eight out of ten."
"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."
