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

"I am pleased with this solution and the features it offers right now."
"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 pipe filter application is an outstanding feature."
"It does a lot for you for intrusion protection and as an antivirus. The threat management bundle is worth the money. You don't need another company to monitor your web traffic for you. You can do everything yourself on the firewall. You restrict your own black list for people on the firewall. You don't need to pay some other company for another product to do that for you. The firewall can do that for you. So, it's an easy-to-use product for people to be independent. They don't need to rely on other vendors to do what the firewall can do. They can do everything."
"The most useful functionality of Fortinet FortiGate is the user interface, multiple engines, and their cloud with the latest integrations, and additionally, the Security Fabric tool is very good."
"I've never had a problem with Fortinet FortiGate support, so I'd rate it ten out of ten."
"It enables our organization to become more productive, and it protects our NetWare from viruses and malware."
"The impact of SD-WAN on the network performance has been significant."
"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 absolute best part of Sangfor NGAF is their support; it's a 24/7 support channel, and the last time I requested their assistance I got a reply within three minutes and they helped solve the problem immediately."
"The most valuable feature of Sangfor NGAF is its integration."
"The support from Sangfor NGAF here in Pakistan is great."
"We've found the technical support to be helpful."
"It enables us to not only detect but also prevent various types of incoming threats, allowing us to take appropriate corrective actions and exercise control over the network."
"SSL VPN is the best feature."
"The product is very fast and reliable."
"We use the web sensor, the virus blocker, the spam blocker, bandwidth control, application control, and firewall options, and we're quite happy with all of it."
"Untangle NG Firewall is something that I recommend, although we have only tried the software version."
"Having various solutions in one appliance, one portal, that's easy to implement, with excellent customer service makes for a sound solution."
"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."
"​It is very easy to deploy and monitor. ​"
"Web filtering is very reliable."
"None of my clients has had a ransom or breach using Untangle, whereas my Cyberoam and Sophos clients have been breached."
"The reason we chose this solution is because of their support, which is hands down the best support that I have had with a firewall."
 

Cons

"There could be improvements in the mathematical algorithms used for behavior analytics of traffic."
"Their licensing should also be improved. The activation or renewal of the product should be done from the date of renewal, not from the date on which the license expired."
"The inability to scale the FortiAnalyzer to match our growth necessitates the purchase of new hardware."
"Technical Support: This is where Fortinet stumbles. The support is farmed out overseas to techs that are not very knowledgeable about the Fortinet products."
"Stability and technical support are the two major issues I have found with Fortinet."
"Fortinet FortiGate could improve the user interface. There should be more functionality and options through the GUI."
"It is essential to leverage its capabilities more professionally to achieve an even higher level of security."
"The support is inadequate. The support staff I have dealt with lately are very rude. Some support staff are not up-to-speed with the technology. They basically read a script."
"The tool is expensive."
"The firewall system needs gradual improvements because there are more threats and challenges in the world every day."
"It would be ideal if the solution offered SD-WAN capabilities."
"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."
"It has an issue with the Sangfor Cloud Platform rather than the firewall. When we run a virtual machine, the window tabs display Chinese characters."
"The product must provide more IPS features."
"Sangfor could improve their interface capacity on the 5100 series model and upgrade their hardware from one gig to 10 gig. This would improve the overall throughput."
"They need to improve their research team and they need to study their data to analyze it and build the product."
"The web content filtering needs improvement."
"We seek the availability of the hardware in our region. The hardware-based firewall from Untangle is currently not available in our region."
"The ability to setup a DDNS for each WAN independently would be a very handy feature."
"The pricing should be reduced because it is expensive."
"They don't have any feature that allows you to drop the session."
"The common center facility that Untangle provides should be available on-premises."
"The management console for partners is a bit tricky (buggy)."
"The pricing should be reduced because it is expensive."
 

Pricing and Cost Advice

"If you compare Fortinet FortiGate with Sophos and other firewall products available in the market, this solution is affordable."
"On a scale of one being cheap and ten being expensive, I rate the tool's price as an eight."
"Currently, we are paying about $1,500 a month for three sites."
"They are very competitive, but we like to have the factory warranty taken care of."
"For the price, I'd rate it a ten because it's very cost-effective."
"Its price is affordable and lesser than Cisco. Cisco is expensive. In terms of licensing, there is only one issue. If a customer's license has expired a month ago and they do the renewal after one month, Fortinet renews the license from the start of the previous month. The activation of the product is done from the previous month, not from the date of renewal. The customers usually shout and complain that because they are paying today, the renewal should start from today. The support contract renewals or licensing should be renewed from the date of renewal, but Fortinet starts from the day it had expired. It is a loss for customers. They might have had some problems because of which they did not take the license one month before. Fortinet should work on this. Cisco doesn't do this. Cisco always starts from the day they apply for the license."
"As far as I'm aware, in our case, it's just a yearly pricing arrangement with no additional licensing costs."
"It is expensive. You need to pay for the subscription every year, which is very expensive. The subscription includes technical support and hardware exchange in case of failure."
"Sangfor NGAF is a cheaply priced product, especially if I consider the previous product that was used in my company."
"I rate the product price as one on a scale of one to ten, where one is low price and ten is high price."
"When it comes to the price of firewall solutions, Sangfor NGAF takes the cake."
"If you know you have around 200+ computer users on your network, then the Sangfor NGAF 5200-F-I model would be the minimum recommended model for that amount of users. This model includes modules for packet filtering, deep packet inspection, malware scanning, DSCP filtration, and many other features."
"We purchased one year technical support and return to factory support, and we also purchased one-year technical support services. So those were additional."
"It is one of the cheapest tools in the market."
"In my opinion, the price of the tool is good in the Pakistani market. We can easily get discounts if needed."
"For over 2000 users, the cost is around 5000 to 6000 USD. If you want a web application firewall, you have to purchase an additional license for it."
"The pricing model is better than with SonicWall."
"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."
"The setup cost is about $2000 to $3000 per year."
"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."
"For the home use, it's cheap."
"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."
"It is the most cost-effective to use."
"The tool's pricing is moderate, and licensing costs are yearly."
