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

"The beauty is the price performance ratio is great with FortiGate, as it provides all the features we need and the price is comparable with other firewalls, making it quite competitive with firewalls that have similar features."
"The most valuable features are the enterprise modeling and the simple interface."
"We have found it to be very reliable and that's why our teams and various users in our company use it as our main firewall every day."
"The common valuable feature for FortiGate is its UTM functionality, which includes various features under a license that is commonly implemented."
"The solution is very, very easy to use."
"There are lots of features and most of them are deployed for internet security. Users are protected if they accidentally go to some malicious sites."
"We find it's good for managing the network and offers good defense against attacks."
"Routing and reporting are two areas where the product has an added advantage compared to any other product."
"It offers application control features."
"The solution is quite safe and good, and furthermore, it is very good for different environments."
"So far, the performance and reliability of the product have supported our company's critical network traffic."
"In four steps one can configure the entire firewall."
"The VPN connectivity feature is really nice."
"The tool's performance is good."
"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. They helped solve the problem immediately."
"It is a stable solution."
"Web Filter is effective, Web Cache offers bandwidth savings, and the VPN setup is easy."
"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. ​"
"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 initial setup is very easy."
"The Untangle firewall is a software firewall, so it runs on generic hardware, and 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."
"From a small business perspective, it's a very good product because you don't really have to be that technical in order to use it."
 

Cons

"I see room to explore its integration with Secure Service Automation for a more comprehensive security view."
"The SD-WAN functionality is a bit overly complicated and not fully documented."
"The firewall engine is not so strong as of now, in my opinion... My second concern is that, while they have Zero-day vulnerability and anti-malware features, the threat engine needs to be strengthened, its efficiency can be increased."
"There are no areas that need improvement at this point in time."
"Quality control on their firmware versions needs improvement."
"The stability of Fortinet FortiGate could improve."
"The management consoles can be improved."
"The non-error conserve mode has room for improvement."
"Lacks consistency in terms of filtering certain websites and applications."
"The product must provide more IPS features."
"Sangfor NGAF could improve the policies and default criteria. They could be much better."
"The solution has too many bugs and these slow down the implementation."
"They need to improve their research team and they need to study their data to analyze it and build the product."
"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."
"An area for improvement would be the number of ports defined on the box."
"The GUI needs to be improved, lacks logic in some areas."
"Web-filtering policies could be improved."
"They don't have any feature that allows you to drop the session."
"We have a minor issue when assigning IP addresses in the ARP tables. You should be able to go into the ARP tables, look at the IP address and say, "Nope, they need to be on this side on this IP address." The ability to set a DHP reservation from the ARP tables would be great. It's no big deal, but it would be nice to have."
"They don't have any feature that allows you to drop the session."
"It does have multi-factor authentication in some areas, but I would love to see a more widely implemented version of that on the devices themselves."
"The storage is minimal, so we have to set the system to delete data after seven days."
"The ability to setup a DDNS for each WAN independently would be a very handy feature."
"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."
 

Pricing and Cost Advice

"If the customer is looking for SD-WAN, it comes free with FortiGate."
"The price of Fortinet FortiGate is the lowest in the market."
"The platform offers a reasonable price point compared to its competitors."
"Before choosing a piece of equipment you have to take into account the cost-benefit offered by each one. Sometimes it is not worth paying a very cheap price to have a minimum level of security."
"For the price, I'd rate it a ten because it's very cost-effective."
"The price is high compared to some of the other solutions."
"The price of Fortinet FortiGate is reasonable for an SME."
"As far as I'm aware, in our case, it's just a yearly pricing arrangement with no additional licensing costs."
"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."
"It is one of the cheapest tools in the market."
"The product is very cost-effective compared to other brands or vendors."
"For four to five physical appliances for a licensed firewall, it costs approximately $4,000."
"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 price could be more competitive."
"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."
"The pricing is reasonable."
"For the home use, it's cheap."
"It is not expensive. It is cheaper than Fortinet."
"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 solution is fairly priced."
"The pricing model is better than with SonicWall."
"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."
"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."
