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.

Offers good features like URL filtering, IPS, and IDS to users

We received an update for the tool in July. The update was provided for the tool as there was a problem with the firewall, where too much memory was consumed, and the firewall was hanging a lot. When we updated the tool's features, everything became okay. The tool only had some memory-related problems. It took the tool a month to fix the issues.

Deputy General Manager at Sagility

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

"The most valuable feature of FortiGate Next Generation Firewall is its SD-WAN."

"It has a valuable SD-WAN feature and provides good performance."

"Security management tool that's easy to integrate and easy to work with. No issues found with its stability and scalability."

"What's most important is the ease of use."

"Provides good firewall security and has great VPN features."

"Using this product makes the VPN seamless and almost invisible to me in the sense that I don't have to think about it."

"One of the nice things about FortiGate is that it can be deployed on the cloud or on-premises. You can actually do both. That's the biggest reason why I stick with this solution as opposed to something like Cisco Meraki. Another nice thing is that I can log directly into a FortiGate or get to it through their FortiCloud access products. They're pretty reliable and consistent. One of the reasons why I started using the product was their single pane of management. I can deploy their line of firewalls in conjunction with their switching and access points, and I can manage the entire network from one interface. I don't have to log into one interface for the firewall, another one for the access points, and another one for the switches. These firewalls have access point controller functionality built right into the system, so I don't even have to purchase additional devices to manage them."

"It's very easy to configure."

More Fortinet FortiGate pros

"Working with the Hillstone E-Series has, from a remote perspective, allowed me to give my clients a secure connectivity."

"The installation is easy, we have not had any complaints from our customers."

"The most valuable feature of the Hillstone E-Series is its user-friendliness."

"The initial setup was straightforward. It only took a few hours to deploy."

"The most valuable features of the Hillstone E-Series are its hardware capacity, innovation, and the throughput that the hardware can take."

"The most valuable feature of the solution is the ransomware protection that the tool offers."

"Five out of five ROI."

"I am impressed with the application filtering feature."

More Hillstone E-Series pros

"The product’s firewall and VPN package are fantastic compared to any other solution."

"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."

"It provides in-depth visibility into your network, ensuring that traffic flowing into your organization, be it from offices or individual users, is effectively filtered and secured through multiple layers of protection."

"The technical support from Zscaler was excellent."

"Zscaler is still a very good product."

"It helps a lot of companies to reduce their downtime. Also, It helps businesses in terms of being secured and protected from any threats."

"The scalability is okay. We have around 2200 people using this solution."

"The solution is scalable."

More Zscaler Cloud Firewall pros

Cons

"The solution could improve by having some additional features, such as IBS and better cloud administration."

"I have used technical support and they could improve."

"Though the tool's GUI is user-friendly, it can be considered as an area with certain shortcomings where improvements are required."

"There's always something new that can be added or fixed."

"One of the weaknesses of the solution is something we noticed, especially after comparing the tool with SD-WAN features, since, unfortunately, in a massive scale size environment, the solution is not good. I"

"Fortinet FortiGate should improve the VPN tokens."

"There are some complex administration tasks in their administration portal. That needs to be improved."

"The room for improvement is to have more flexibility on the virtual machines of their next-generation platforms."

More Fortinet FortiGate cons

"The tool needs to improve its price."

"SSL VPN license cost is not cheap."

"The current usage reporting is very basic."

"I am not sure if this solution offers active directory integration. Adding that feature will definitely be an advantage."

"The tool provides just a general report. It does not provide a granular report. Hence, the tool should work on its reporting feature."

"The solution doesn't have a web proxy built into the system like Sophos. This is something they should work to change."

"The tool only had some memory-related problems."

"Support from Hillstone E-Series has a shortcoming that needs improvement."

More Hillstone E-Series cons

"Data Leak Prevention is only for web filtering and there is no protection for email."

"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."

"Instead of the standard license, they should certainly provide customers with the visibility to access and view the logs."

"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."

"I don't have the visibility of a control dashboard or a network management system."

"There are some areas it could improve when it comes to blocking, we have to block some things manually. For example, if we block a top-level domain we have seen that the new IPs come through, the IPs are not blocked. There should be some more granular way of doing it. My only request is if you're blocking something at a top level, the sub-level sub-domains and all those other IPs should be blocked too automatically."

More Zscaler Cloud Firewall cons

Pricing and Cost Advice

"Some of our customers are using Sophos and SonicWall due to price concerns, as they can't manage the pricing of Fortinet FortiGate."

"The price is relatively expensive compared to other solutions which are providing similar features."

"The pricing is better compared to other solutions like Check Point, Arista, or Cisco."

"We purchased a five-year bundle package, which worked out cheaper than competing solutions."

"There is a license to use Fortinet FortiGate."

"Easy to understand licensing requirements."

"I rate FortiGate Next Generation Firewall a five out of ten for pricing."

"I'll rate FortiGate's pricing a five out of ten since it is moderately priced."

More Fortinet FortiGate pricing and cost advice

"Hillstone's pricing is economical and neither very high nor very low."

"The tool's pricing is reasonable. It depends on the model. The product's pricing is around 600 USD. You need to buy a software license to activate the features. You need to pay around 150 USD for that."

"The cost per year for licensing, and hardware, is approximately $850 for the basic plan."

"The licensing model is very complex with many subcategories of licenses you can purchase. They could make it more simplified for customers to understand."

"There are different subscription models available."

"Zscaler is priced too high compared to the cost of Fortinet."

"It is expensive for small businesses."

"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."

"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."

"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."
