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.

Thorough with all-in-one security functions and good affordability
The all-in-one gateway security functions and the ability to install it on generic equipment stand out. The centralized management console is great. I can template my installations and configurations. My ability to monetize it as a gateway security appliance to offer enhanced service offerings allows me to increase our price point. I provide it as a managed device to many of our clients. I take on the initial costs and charge them a monthly fee. They have threat detection.
Vikram Srirama. - PeerSpot reviewer
A highly scalable solution that helps monitor and block undesired, non-standard traffic
Zscaler Cloud Firewall is a cloud-based solution. Zscaler Cloud Firewall is a good product. Since it's a SaaS product, most of the maintenance of devices is eliminated, and it is bundled with your secure web gateway. People should use Zscaler Cloud Firewall for their remote users or work-from-home users. Overall, I rate Zscaler Cloud Firewall a nine out of ten.

Quotes from Members

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

Pros

"I would advise others considering or evaluating the Fortinet FortiGate to buy it."
"The product's most valuable feature is the ease of deploying IoT security with a single click. Additionally, the frequent updates to the online database ensure that our security measures are always up to date, enhancing our protection against emerging threats."
"Fortinet FortiGate SWG's content is its most valuable feature."
"It is very flexible to use."
"FortiGate's SD-WAN capability is the most useful feature for us."
"The usage in general is pretty good."
"I like that you are able to manage FortiGate from the FortiManager to create a more centralized environment."
"Fortinet FortiGate meets all the security demands of my industry. It covers endpoint security, including web interface, DNS security, and ELP. I'm currently using the latest version. The features that have most improved our network security are Web Control, filtering, application control, IDS, IPS policies, and Deep SSL inspection."
"​It is very easy to deploy and monitor. ​"
"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."
"The interface is very good."
"The product’s most valuable features are endpoint protection management, load balancing, and connectivity with Active Directory."
"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."
"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."
"We find the web filter very valuable."
"I like the ease of deployment and its flexibility. We don't need to deal with license, quotes, procurement, delivery, and installation. Everything is software-based, and it's very easy to operate."
"The scalability is okay. We have around 2200 people using this solution."
"The visibility and log availability offered are highly valued for troubleshooting purposes, and this is a key factor driving customer interest in the firewall module."
"Once you have Zscaler running you have access to configure it however you want."
"The product’s firewall and VPN package are fantastic compared to any other solution."
"Includes advanced tech protection."
"The initial setup is straightforward."
"It is a stable solution."
 

Cons

"They should make the product user-friendly and enhance the security features."
"The security of Fortinet FortiGate could improve."
"The support team for Fortinet FortiGate needs to be more customer friendly."
"In an incident, after a restart, Fortinet FortiGate did not connect to FortiGuard servers. Due to that reason, on the customer end, all websites got blocked."
"For the migration, everyone has a firewall in use and I am selling Fortinet. Typically, I am replacing another firewall. Previously, there was a tool available to convert configurations from one firewall, such as Palo Alto, to Fortinet, but this tool is no longer free. If it could be made free again, it would be very beneficial."
"In my opinion, Fortinet FortiGate could be improved by making the appliance smaller than what we have here, as it is pretty big."
"While FortiGate is cheaper than most other solutions, we're seeing increased license renewal costs. Most of our clients are asking for more significant discounts because the price is going up."
"Fortinet FortiGate needs to improve to be on par with its competitors, such as Palo Alto and Sophos. They are the market leaders. Fortinet FortiGate needs to improve its capabilities. However, we are happy with Fortinet FortiGate."
"The web content filtering needs improvement."
"The user interface, training, and general product innovation need improvement."
"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."
"The management console for partners is a bit tricky (buggy)."
"The storage is minimal, so we have to set the system to delete data after seven days."
"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."
"The pricing should be reduced because it is expensive."
"It would be nice to have some sort of a form factor, a physical form factor perhaps, or virtual machine that you could install on devices or on a cloud, and have some cloud computing."
"Certain criteria need to be met if you want to scale this solution."
"Instead of the standard license, they should certainly provide customers with the visibility to access and view the logs."
"Apart from the issues associated with the product in areas like the DC performance issues and DC failover, Zscaler Cloud Firewall's IP should not have a proxy IP."
"Because it's on cloud, it doesn't allow application of extra settings."
"The issue right now is probably that Zscaler is not providing web browser isolation. Another solution, Menlo, offers this. For one customer, we had to send traffic to Menlo to do the isolation for us. It was requested by the customer so that they could integrate any iframe. Zscaler needs to add this type of feature in their next release."
"The product could improve its integration with some legacy systems."
"We are having some issues with internet access being denied when organizational ID-based policies change. For example, a lower level employee ends up getting the same level of access as that of a higher level employee."
 

Pricing and Cost Advice

"The cost of Fortinet FortiGate is competitive and not expensive compared to other enterprise- grade solutions. On average, the license cost per year is around seventy percent of the firewall's purchase price."
"The pricing for this solution is good."
"Compared to Palo Alto, which we have used in the past, pricing and licensing are okay."
"Pricing for this product is comparatively lower than other products. It's an affordable solution, but when expanding the number of users, they'll ask you to replace the model, so that's an added cost."
"The price of Fortinet FortiGate is reasonable for an SME."
"Fortinet FortiGate is cheaper than Palo Alto. It is about 20% cheaper."
"If we have an older version, the support costs get quite high."
"As far as I'm aware, in our case, it's just a yearly pricing arrangement with no additional licensing costs."
"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 tool's pricing is moderate, and licensing costs are yearly."
"The setup cost is about $2000 to $3000 per year."
"It is the most cost-effective to use."
"For the home use, it's cheap."
"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."
"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."
"There are different subscription models available."
"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 product is a bit expensive compared to the solutions offered by its competitors, like Palo Alto. There is a need to make yearly payments towards the license in charges associated with the product."
"The licensing is on a yearly basis. It is somewhere around 30 or 40 pounds per user for our organization."
"It is expensive for small businesses."
"There are licensing costs, and I would not say that it's a cheap vendor."
"It is not the most budget-friendly solution, but it's important to consider its overall value."
"There is an annual license required for the use of the Zscaler Cloud Firewall."
