Cloud features enhance security measures and simplify network management
I've dealt with many firewalls, such as SonicWalls, UniFi, pfSense, and Cisco. We found SonicWall very confusing for the average network engineer or network administrator. I don't recommend SonicWall due to its hard-to-find auditing process for exploits. Although they have fewer exploits, when they do occur, they're significant. With Fortinet FortiGate, you can access the whole firewall, with no hidden spots. pfSense is great, however, it requires a lot of manual work and has no Cloud Connect or easy management from an MSP's perspective. Palo Alto is another option that's great, but their price point isn't for everyone, especially for medium and small businesses; a $10,000 investment doesn't necessarily fit into most budgets. UniFi is another product we've started to use more alongside Fortinet FortiGate, as they have almost all features without a license, with advanced rules that are relatively inexpensive compared to Fortinet FortiGate's $1,500 a year. Fortinet FortiGate and UniFi are the two firewalls we primarily deal with. My opinion is that UniFi has better integration and oversight of the environments compared to Fortinet FortiGate.

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.

User has benefited from stable performance and effective completion of security tasks
I use it mostly for VPN and for some firewall solutions When considering my main use case with VPN, I can say that I got the Zyxel Unified Security Gateway, and it works fine. However, we are thinking about using a different solution based on open source because Zyxel Unified Security Gateway…

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 feature of Fortinet FortiGate is the simple configuration."
"The ease of use and the user-friendly interface are the beauty of this firewall."
"The services from Fortinet products are very, very good, the WIFI that Fortinet provides for us is fantastic, the VPN tunnel is very stable with more than one option which is helpful, and it is a very, very, very useful tool."
"Fortinet FortiGate's reliability is valuable."
"The UTM feature is quite good. FortiAP is easy to deploy because both Fortigate and FortiAP are under the same brand. Otherwise, you need to do more work on the configuration."
"Their web interface to manage it is excellent, even compared with other providers."
"What I appreciate the most about Fortinet FortiGate is that it has a very large integration using Fabric, which they call Fabric Connectors."
"Their reliability and their policy of pre-shipping replacements when a unit has failed."
"We use the web sensor, the virus blocker, the spam blocker, bandwidth control, application control, and firewall options, and we're quite happy with all of it."
"Web Filter is effective, Web Cache offers bandwidth savings, and the VPN setup is easy."
"None of my clients has had a ransom or breach using Untangle, whereas my Cyberoam and Sophos clients have been breached."
"All features are useful. We are using premium features such as bandwidth sharing, failover, web filters, SSL controls, antivirus, and VPN. We use these features to the fullest. These features are available in the paid firewall license, not the free one."
"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."
"We have scaled it from 10 users to 1,000 users without any issues."
"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."
"They have a command center that makes it easy to log into and see all of your appliances nationwide."
"The Zyxel Unified Security Gateway solution is stable and does its job effectively."
"This is a capable appliance and the standard features work well for us."
"The solution can scale well."
"The cost is very low."
"The most valuable features of the solution stem from web filtering, malware protection, and antivirus."
 

Cons

"The support structure needs to be improved because every time we contact them, there is a delay in the response."
"They should consider making some improvements regarding the pricing."
"One drawback of Fortinet FortiGate is that they provide two types of models: one with a hard disk and another without. The model without a hard disk has very low ROM where you can store very few logs, after which you need to upload it to the cloud or purchase a firewall with SSD. That's the only drawback."
"I would like to see better pricing in the next release, as well as a simplification of the installation."
"Another issue is how deduplication services don't work reliably after enabling deduplication on Fortinet."
"Their licensing should also be improved. The activation or renewal of the product should be done from the date of renewal, not from the date on which the license expired."
"Fortinet FortiGate could improve by having a frequent ask questions(FAQ) area for people to receive quick answers to popular questions. Additionally, it would be beneficial to have an SMS notification feature. For example, if you cannot access your email you could receive an SMS message."
"We had a minor problem where there was a major system upgrade on the hardware platfrom and the Mac client was not available as soon as it might have been. The PC client was available immediately, but we had to wait a month or so, before there was a mac client. I was slightly irritated that it was not ready on time, but it was eventually resolved."
"The common center facility that Untangle provides should be available on-premises. There are great corporations here in Mexico that like the Untangle solution, but they don't like the fact that the monitoring and access to the appliance are in the cloud. They request for the common center facility to be available and installed on-premises."
"The ability to setup a DDNS for each WAN independently would be a very handy feature."
"Whenever there are a large number of endpoint VPN clients, connectivity becomes slow."
"They don't have any feature that allows you to drop the session."
"The pricing should be reduced because it is expensive."
"The local technical support does not understand the product very well."
"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."
"We seek the availability of the hardware in our region. The hardware-based firewall from Untangle is currently not available in our region. It should have threat protection on a real-time basis. This feature, available in Check Point and Sandstorm kind of scenario, is currently missing in Untangle NG Firewall."
"I have never seen it in any company that I've worked with before, and I would advise other companies not to buy it."
"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. The advanced UI allows me to do whatever I want, but this is where the issue of speed exists."
 

Pricing and Cost Advice

"On a scale of one being cheap and ten being expensive, I rate the tool's price as an eight."
"We just pay a flat monthly fee to the vendor for the support."
"Some of our customers are using Sophos and SonicWall due to price concerns, as they can't manage the pricing of Fortinet FortiGate."
"It cost us around $73,000 for three years."
"It is an expensive solution."
"By default, they give SD-WAN along with the firewall. They don't have separate licensing for the SD-WAN functionality. However, they have security licenses that are sold separately on a subscription basis. Customers can consume these security features to protect their users from internet traffic."
"It's a year based license."
"The solution is cheap."
"For the home use, it's cheap."
"It is not expensive. It is cheaper than Fortinet."
"The setup cost is about $2000 to $3000 per year."
"The tool's pricing is moderate, and licensing costs are yearly."
"The solution is fairly priced."
"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 pricing model is better than with SonicWall."
"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."
"The price of Zyxel Unified Security Gateway is good compared to other similar products in the market."
"This gateway is pretty cheap."
