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

"The most valuable features of Fortinet FortiGate are its SD-WAN capabilities, such as dynamic routing, and other features, including security options such as antivirus, IPS, and IDS—all integrated into one device."
"It's inexpensive compared to some of the other technology out there."
"The best features of this tool include threat protection, email filtering, and web filtering, and FortiAnalyzer's integration with the firewall and FortiSASE is beneficial."
"Two aspects I'm happy with regarding Fortinet FortiGate firewall are the easy user interface and its resilience during power interruptions."
"The GUI is very simple, and what is very good is that every product, regardless of size, has the same interface."
"Fortinet offers the latest versions to cater to the needs of enterprises."
"Secure, user-friendly, stable, and scalable network security solution. Installation is straightforward."
"The technical support is great."
"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."
"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."
"In four steps one can configure the entire firewall."
"The stability of Sangfor NGAF is good."
"The price versus value is good because the solution is less expensive than Sophos, Fortinet, or SonicWall."
"We can utilize our own network rather than paying for a private one."
"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."
"So far, the performance and reliability of the product have supported our company's critical network traffic."
"It is not attached to an appliance, meaning if you get a good PC/server, then you can already run a firewall."
"None of my clients has had a ransom or breach using Untangle."
"Since it can be put on any box, the scalability is fantastic."
"Its detection, antivirus, and filtering features are the most valuable. The facility to connect by using the VPN connection is also a very valuable feature. It is very strong, secure, and reliable. We have implemented the Untangle solution in all hardware. It is also a user-friendly solution. It is easy to learn and easy to configure."
"The initial setup is very easy."
"The product’s most valuable features are endpoint protection management, load balancing, and connectivity with Active Directory."
"The majority of our clients are very small businesses, and Untangle devices have been fantastic for these small clients. We've basically standardized our stack to just simply use Untangle. We include the hardware and the service option, which makes it very easy and affordable for us to just simply push that into the monthly per-user costing that we provide as a managed services provider. It's really a no-brainer. They're easy to use, and they're easy to set up and configure. Support is generally good about resolving any issues that we have. We haven't had any real complaints."
"What I like about this product, which is the reason that we continue to use it, is that you can install the software version on your own hardware. In case there is a problem with the hardware, we can just install the firewall in another machine and restore the configuration."
 

Cons

"It would be good if they had fewer updates."
"For Fortinet FortiGate, their code development would definitely be something they need to improve on to reduce vulnerabilities that need to be patched."
"Fortinet FortiGate IPS could improve the configuration. In some use cases, there can be some configuration conflicts."
"The solution's framework needs to be frequently updated in order to have a stable solution."
"They've become quite expensive."
"There is a need for enhancement with the signature management, improving the datasheet numbers, and scalability issues."
"I would like to see improvements in some of the hard drive features on FortiGate so that we can generate reporting within a single box."
"For Fortinet FortiGate, their code development would definitely be something they need to improve on to reduce vulnerabilities that need to be patched."
"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."
"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."
"I feel Sangfor should follow the hierarchy and close deals via resellers instead of closing it all with their own team."
"The support offered by the product has certain shortcomings where improvements are required. The knowledge levels and response time of the support team need improvement."
"The tool is expensive."
"Sangfor NGAF could improve by refining its application control policies, especially in addressing challenges with certain types of applications."
"Scalability for any network device is not very easy in terms of vertical scalability."
"The solution should be able to work in a hybrid setup."
"The web content filtering needs improvement."
"The user interface, training, and general product innovation need improvement. Enhancements could also be made to their reporting and accessibility."
"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."
"Web-filtering policies could be improved."
"For the web filter, I think they can do better especially on the free model."
"The user interface, training, and general product innovation need improvement."
"The solution's licensing count could be improved."
"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

"Its price is good."
"The product is expensive."
"It is affordable. Palo Alto is much more expensive than Fortinet."
"At the time we bought them, I was satisfied with their pricing; I don't know how the new pricing will be."
"The license is too expensive to renew. The license renewal process is also complex."
"The price for the Fortinet FortiGate is reasonable. Secure SD-WAN is free of charge. If you have their firewall, it's free of charge. It's very tempting."
"They are more expensive than others."
"We pay for the solution annually."
"When it comes to the price of firewall solutions, Sangfor NGAF takes the cake."
"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 costs about 8 to 10 thousand dollars per year for 500 users, standard licensing fees included."
"The price is unmatcheable."
"For four to five physical appliances for a licensed firewall, it costs approximately $4,000."
"In my opinion, the price of the tool is good in the Pakistani market. We can easily get discounts if needed."
"The product is very cost-effective compared to other brands or vendors."
"Sangfor is cheaper than competing vendors."
"The setup cost is about $2000 to $3000 per year."
"The tool's pricing is moderate, and licensing costs are yearly."
"It is the most cost-effective to use."
"The pricing model is better than with SonicWall."
"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."
"It is not expensive. It is cheaper than Fortinet."
"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."
"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."
