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 security features are about the best that I've seen anywhere."
"It's great for capturing the traffic and troubleshooting it."
"Good load balancing feature."
"Palo Alto did a good job on the IPv6 interfaces and security policies."
"I would rate FortiGate Next Generation Firewall (NGFW) as a solution a 10 out of 10."
"In a scenario where FortiGate Next Generation Firewall (NGFW) notably enhanced my customer's network performance, we discussed many points."
"It provides security purposes, and it makes our network safe from outside attacks."
"We are Sangfor Gold partners and I'd recommend this solution for the SMB market, as it is cost-effective and reliable."
"The VPN connectivity feature is really nice."
"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."
"The solution is quite safe and good, and furthermore, it is very good for different environments."
"Sangfor is a good solution that provides a WAF and firewall solution. Most other vendors, like Sophos and Fortinet and Cisco, only provide one solution. That's a valuable feature of Sangfor."
"When it comes to the price of firewall solutions, Sangfor NGAF takes the cake, as it is cheaper than Fortinet, Sophos, Check Point and Palo Alto."
"I think this solution is a very good example of a proactive solution that can detect problems and immediately fix the problems or issues."
"So far, the performance and reliability of the product have supported our company's critical network traffic."
"Web Filter is effective, Web Cache offers bandwidth savings, and the VPN setup is easy."
"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."
"The web blocking for my clients and the application control are valuable."
"The product helps small and medium enterprises secure their networks from intrusions. It also has features like DNS blocking."
"It has improved and secured multiple clients."
"The threat prevention features of Untangle NG Firewall have helped my network security management, and I find them very good."
"The solution's most valuable feature is the content filtering."
"The all-in-one gateway security functions and the ability to install it on generic equipment stand out."
 

Cons

"Updating the software during issues can be quite convoluted, especially if there is an unexpected attack, such as on a Saturday."
"I often ask for help from the local provider. I haven't found the required efficient help."
"The price of FortiGate should be reduced because there are some other leading products that are cheaper."
"It could always be more secure."
"We have never encountered any issues with it. The price and deployment part of Fortinet FortiGate is good, but it can always be better."
"Fortinet FortiGate is not very easy to use. The navigation could be improved to make it easier to use."
"The pricing could always be better."
"When it's overloaded, it works slower and overheats."
"It would be ideal if the solution offered SD-WAN capabilities."
"The cost of licensing is very high compared to other firewalls available here. There should be improvements in hardware scalability, allowing for more storage and memory capacity."
"The web interface needs to be improved, making it more user-friendly."
"There is room for improvement in dependency on certain infrastructure, like the DNS dependency on the current DNS server that the company has. It should be standalone. It should not depend on any other DNS server."
"I think the GUI needs to be improved, there are a lot of areas where the panes do not make sense."
"The solution has too many bugs and these slow down the implementation."
"The tool is expensive."
"The tool's support is an area of concern where improvements are required."
"They don't have any feature that allows you to drop the session."
"The biggest challenge that we have with this solution is local support. The local support is a problem in our area."
"The product needs to have a better support group for its online support, specifically for its help desk."
"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."
"The pricing should be reduced because it is expensive."
"The product needs to have a better support group for its online support, specifically for its help desk."
"The web content filtering needs improvement."
"The pricing should be reduced because it is expensive."
 

Pricing and Cost Advice

"Compared to Palo Alto, which we have used in the past, pricing and licensing are okay."
"It is around $50,000 per month."
"FortiGate Next-Generation Firewall is cheaper than Cisco or CheckPoint."
"It is an inexpensive solution."
"The product pricing is reasonable."
"FortiGate Next Generation Firewall is an expensive solution."
"Fortinet's pricing is more straightforward than other solutions. If Fortinet doesn't stick out when you're searching for a solution, you are a glutton for punishment. You only need to know two things when purchasing a Fortinet solution: your total bandwidth and bandwidth at the site. You need to estimate the future bandwidth with other solutions if your customer plans to upgrade."
"Its price is reasonable. They have a clear pricing policy. It is not complicated by the number of VPN users at a time. We know what the price is. The yearly subscription for the security license is rather high, but it is all included for whatever number of users you have and the kind of functions you need."
"The price is unmatcheable."
"The price could be more competitive."
"Price-wise, I would not consider Sangfor NGAF to be a cheap product. It is an expensive firewall solution, though not as expensive as something like Palo Alto, which is costly. However, the higher price point is justifiable given the feature set the tool provides that other firewalls may not offer in a single dedicated appliance."
"The product is very cost-effective compared to other brands or vendors."
"The solution has a TCO that is 32% to 50% less than Sophos, Fortinet, and SonicWall."
"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 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."
"Sangfor NGAF is a cheaply priced product, especially if I consider the previous product that was used in my company."
"For the home use, it's cheap."
"The tool's pricing is moderate, and licensing costs are yearly."
"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."
"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 setup cost is about $2000 to $3000 per year."
"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."
"The pricing model is better than with SonicWall."
"It is the most cost-effective to use."
