Featured Reviews

Vasu Gala - PeerSpot reviewer
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.
Gary-Downey - PeerSpot reviewer
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.
Alexander Azikov - PeerSpot reviewer
A robust appliance that is reasonably priced and straightforward to set up
Although manageable, the user interface is a little bit slow and could be improved. There are two user interface options available, namely the basic and the advanced. The basic UI is not very good and doesn't have a lot of features, although it is fast. The advanced UI allows me to do whatever I want, but this is where the issue of speed exists. At one of our sites, the CPU utilization was very high, and for no reason. Technical support needs to be more responsive to requests.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"This product is definitely scalable."
"The solution’s initial setup is very easy."
"The scalability is easy with switches and access points that are basically plug-and-play for the most part."
"There are many features packed and significant flexibility from Fortinet FortiGate in being able to do numerous things."
"What I appreciate about Fortinet FortiGate is that the UI is easier than what I've previously known from Sophos."
"I am content with its user interface and functionalities."
"I like the solution's stability."
"One of the best features of Fortinet FortiGate is that it's a very powerful equipment that gives many security features in a single box with good performance, and the user interface is friendly to use and configure."
"The most valuable features are IPS, MAPI, NAT, and VPN."
"The all-in-one gateway security functions and the ability to install it on generic equipment stand out."
"The solution's most valuable feature is the content filtering."
"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."
"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."
"The product helps small and medium enterprises secure their networks from intrusions. It also has features like DNS blocking."
"They have a command center that makes it easy to log into and see all of your appliances nationwide."
"The web blocking for my clients and the application control are valuable."
"The most valuable features of the solution stem from web filtering, malware protection, and antivirus."
"The solution can scale well."
"This is a capable appliance and the standard features work well for us."
 

Cons

"Technical support for this solution can be improved."
"You do need some IT knowledge in order to effectively work with the solution."
"Security level could be increased."
"The big license options have web filtering, IDS, and a lot of other things, but it's not like they are all good."
"The support is not good because I generally search for solutions online. When I open a case, they usually identify it as a bug they are working on."
"MTBF: Hardware failure is more common when compared to SonicWall or Cisco ASA."
"It is very expensive, and their support is not very good. I hope that their technical support will be better in the future."
"I would like to see the licensing aspect improved because there is a feature we were yearning to use, the bandwidth monitoring feature, but it's licensed separately."
"It would be much easier if there was a mobile app."
"The product needs to have a better support group for its online support, specifically for its help desk."
"The hardware can be improved."
"Whenever there are a large number of endpoint VPN clients, connectivity becomes slow."
"The ability to setup a DDNS for each WAN independently would be a very handy feature."
"The user interface, training, and general product innovation need improvement."
"Web-filtering policies could be improved."
"For the web filter, I think they can do better especially on the free model."
"Sometimes it reboots when you least expect it, and that's the main issue."
"The product has some scalability and data management issues where improvements are required."
"Although manageable, the user interface is a little bit slow and could be improved."
 

Pricing and Cost Advice

"​We saved a bundle by not needing all the past appliances from an NGFW.​"
"It is not expensive as compared to Cisco."
"There is an annual license to use this solution. The prices have been increasing over the years."
"The price of Fortinet FortiGate is reasonable."
"It's very competitive."
"The Indian market is different than the European and American markets. When you compare they need to be a bit more aggressive on pricing."
"The product is a little bit expensive."
"The price of Fortinet FortiGate is affordable. Most of our customers are on a three-year license to use the solution. All the features and support are included in the price."
"It is the most cost-effective to use."
"The setup cost is about $2000 to $3000 per year."
"The pricing model is better than with SonicWall."
"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."
"It is not expensive. It is cheaper than Fortinet."
"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."
"The price of Zyxel Unified Security Gateway is good compared to other similar products in the market."
"This gateway is pretty cheap."
