Manager, Information Technology Operation/Presales at TechMonarch
A stable solution with an intuitive interface and quick customer service
I have been working with Fortinet FortiGate, WatchGuard, Sophos, and SonicWall. I'm not as comfortable with SonicWall because of their UI and limitations. I prefer Fortinet above all other options. When it comes to configuration, I am confident in my ability to handle various tasks, including creating policies such as firewall rules, web policies, and application policies. Additionally, I can configure VPNs and implement load balancing, among other tasks. Overall, I feel much more comfortable working with Fortinet. Fortinet has made significant improvements by integrating AI with firewalls for threat analysis and prevention. In the past 2-3 years, they have launched FortiSASE and SIEM, and they also provide SOC services. Both Palo Alto and Fortinet FortiGate are excellent. While Fortinet FortiGate comes at higher prices, the functionality and support justify the cost. They promptly resolve firmware issues and inform all support providers about configuration changes.

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

"We are very happy with the general bandwidth agility we have seen from one website to another website."
"It increases security posture and is helpful for firewall reporting, intrusion protection, web filtering, and SD-WAN implementation."
"It's very easy to configure."
"Fortigate's most valuable feature is that it doesn't need a push policy when writing rules."
"FortiGate Next Generation Firewall has a very high ROI"
"I would rate the scalability of this product a nine out of ten because it is highly scalable. We have not had problems with customers in terms of scalability."
"The best features of Fortinet FortiGate are the integration of SD-WAN capabilities with Fortinet Unified SASE."
"The Fortinet FortiGate local partners were good. I did not have direct contact with Fortinet support."
"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."
"The product is very fast and reliable."
"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."
"I think the tool has the feature to detect and kill ransomware in three seconds."
"In four steps one can configure the entire firewall."
"It offers application control features."
"Particularly good in the DPI where we can inspect inbound and outbound traffic."
"The price versus value is good because the solution is less expensive than Sophos, Fortinet, or SonicWall."
"The product helps small and medium enterprises secure their networks from intrusions. It also has features like DNS blocking."
"The features I have found the most useful are the web filter, the captive portal, the SSL inspector, and the ad-blocker. They're awesome."
"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."
"It is not attached to an appliance, meaning if you get a good PC/server, then you can already run a firewall."
"The web blocking for my clients and the application control are valuable."
"The interface is very good."
"We find the web filter very valuable."
"Web Filter is effective, Web Cache offers bandwidth savings, and the VPN setup is easy."
 

Cons

"I have contacted the support from Fortinet FortiGate IPS. The service was good but the speed could be better."
"We also have FortiAnalyzer deployed here, so we want to enable the soft functionality of FortiGate and built-in compression for a firewall VPN use case. We want the ability to deploy a gateway for HTTPS enabled on this firewall. It is currently only for use in our headquarters."
"Sometimes I experience stability issues, but sometimes they are related to hardware not functioning properly or related to a software bug."
"One of the problems I was having was with user mapping, and it is an issue for which I have escalated tickets with Fortinet support."
"FortiGate can improve its token system, as it requires a purchase before use."
"The graphical user interface of Fortinet FortiGate SWG is an area of concern where improvements are required."
"Fortinet FortiGate is a very good device overall, though it can be improved in certain areas regarding the licenses, particularly the big one called unified threat management, which has many capabilities."
"The pricing of Fortinet FortiGate IPS could always be improved."
"I feel Sangfor should follow the hierarchy and close deals via resellers instead of closing it all with their own team."
"The product must provide more IPS features."
"The setup phase is quite complex."
"Sangfor NGAF could improve the policies and default criteria. They could be much better."
"The firewall system needs gradual improvements because there are more threats and challenges every day."
"The web interface needs to be improved, making it more user-friendly."
"Scalability for any network device is not very easy in terms of vertical scalability."
"An area for improvement would be the number of ports defined on the box. In the next release, I would like them to develop their provisioning stage of enrolling end devices."
"The ability to setup a DDNS for each WAN independently would be a very handy feature."
"The product needs to improve its mobile application."
"The user interface, training, and general product innovation need improvement."
"There is room for improvement in the logs. Like with Cisco, I can do almost everything and know almost anything about what's running. Untangle works very much out of the box. It's very user-friendly, but it's not engineer-friendly. So, it's good for a home user. For something fairly easy, but at the same time, with good technology to have at home, because at home, I'm not a millionaire or anything like that. So it's not like I'm worried to get hacked. I didn't want something like a Cisco firewall; it would be a bit overkill to have at home. So that's why I went for Untangle. But it lacks a few features. It's just a tick-box kind of thing. So they have apps and turn on and off the apps. The VPN's configuration is all very ticked. They have a few custom configurations, but it's not that much."
"The pricing should be reduced because it is expensive."
"For the web filter, I think they can do better especially on the free model."
"The web content filtering needs improvement."
"The biggest challenge that we have with this solution is local support. The local support is a problem in our area."
 

Pricing and Cost Advice

"The pricing is justified. It's a little pricey, but what you pay for is what you get."
"I do not have first-hand experience with the rice of Fortinet FortiGate, but I have heard the price was reasonable."
"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."
"The price, in comparison to other products is very cheap."
"It scales well if you know what to buy from a physical box standpoint. They seem to offer something for every level."
"When comparing this solution to others, I would rate it a ten out of ten in terms of pricing. However, the issue of requiring a separate license for redundancy is a drawback, and I would rate it a nine out of ten."
"It's very affordable."
"Although the solution's pricing is high, compared with other products, it may be cheap."
"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 price falls in the mid-range, neither exceptionally low nor high."
"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."
"I rate the product price as one on a scale of one to ten, where one is low price and ten is high price."
"Sangfor is cheaper than competing vendors."
"Sangfor NGAF price is reasonable and there is an annual license. However, the maintenance cost can be a bit high."
"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."
"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."
"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 pricing model is better than with SonicWall."
"The tool's pricing is moderate, and licensing costs are yearly."
"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."
"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."
