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

"Web filtering and two-factor authentication are great features."
"The best features of Fortinet FortiGate are that it does the job effectively and protects our environment."
"We can detect any attack of viruses or malware at the first point of contact."
"The most valuable feature of this solution is the analytics."
"The common valuable feature for FortiGate is its UTM functionality, which includes various features under a license that is commonly implemented."
"The customization potential is quite impressive."
"Fortinet FortiGate is stable; I am told that Fortinet FortiGate is one of the best solutions available, and I believe it."
"FortiGate's ability to perform as expected and fulfil our needs has been the most compelling feature for network security."
"We've found the technical support to be helpful."
"Sangfor has the best capabilities for securing connections, securing web browsers, securing servers, and general threat protection."
"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."
"The most valuable feature of Sangfor NGAF is its integration."
"Particularly good in the DPI where we can inspect inbound and outbound traffic."
"It seems to be a durable, stable product."
"The VPN connectivity feature is really nice."
"So far, the performance and reliability of the product have supported our company's critical network traffic."
"NG Firewalls allow us to permit or deny applications we don't want to run. We also use content filtering, SSL inspection, and all the other things we run on the firewall to keep our clients protected and ensure they're not going where they shouldn't. It's a great firewall that works as intended."
"Web filtering is very reliable."
"They have a command center that makes it easy to log into and see all of your appliances nationwide."
"None of my clients has had a ransom or breach using Untangle."
"Web Filter is effective, Web Cache offers bandwidth savings, and the VPN setup is easy."
"The most valuable features are IPS, MAPI, NAT, and VPN."
"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 features I have found the most useful are the web filter, the captive portal, the SSL inspector, and the ad-blocker. They're awesome."
 

Cons

"The price of FortiGate should be reduced because there are some other leading products that are cheaper."
"There could be more modifications."
"The configuration part was challenging, especially converting configurations from another OEM to FortiGate."
"The renewal cost is much higher than other firewalls. It is not reasonable."
"The solution needs to improve its support."
"The initial setup is complex."
"The biggest "gotcha" is that if the client purchases what they call the UTM shared bundle, which has unified threat management on both, it's not as easy to manage if you have more than one firewall."
"We would like to see better pricing."
"The tool's support is an area of concern where improvements are required."
"Sangfor could improve by providing better real-time reporting, as the current reports don't offer the level of detail we need, especially for runtime insights."
"Lacks consistency in terms of filtering certain websites and applications."
"The cost of licensing is very high compared to other firewalls available here."
"The tool is expensive."
"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 increase the number of ports in the firewall."
"The setup phase is quite complex."
"The pricing is not as good as it was some time ago. They've since skipped offering a lot of individual features."
"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."
"The management console for partners is a bit tricky (buggy)."
"The web content filtering needs improvement."
"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."
"The solution's licensing count could be improved."
"The user interface, training, and general product innovation need improvement."
"The hardware can be improved."
 

Pricing and Cost Advice

"We are currently evaluating a Palo Alto solution, and the pricing could be a reason for going for Palo Alto."
"The price of Fortinet FortiGate is reasonable for an SME."
"If the customer is looking for SD-WAN, it comes free with FortiGate."
"The price is highly competitive when compared to other brands that offer similar functionality."
"In the Asian economy in which we operate, FortiGate is expensive."
"If the price of the license in Fortinet FortiGate was less expensive it would be better."
"Its pricing is good. It's average or normal as compared to Palo Alto and Check Point firewalls."
"The pricing for this solution is reasonable."
"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 NGAF is a cheaply priced product, especially if I consider the previous product that was used in my company."
"If one is very cheap and ten is very expensive, I rate the tool's price as three out of ten."
"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."
"Sangfor is cheaper than competing vendors."
"The pricing is reasonable."
"Sangfor NGAF price is reasonable and there is an annual license. However, the maintenance cost can be a bit high."
"In my opinion, the price of the tool is good in the Pakistani market. We can easily get discounts if needed."
"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."
"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."
"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 solution is fairly priced."
"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."
"The tool's pricing is moderate, and licensing costs are yearly."
"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."
"It is not expensive. It is cheaper than Fortinet."
