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.

Network manager admin at Yamaha

Though it helps deal with web traffic or any malicious traffic, it needs to work on its DC performance issues

The product's initial setup phase is moderate in level, so it is neither very complex nor very easy. For the deployment, my company first needs to gather all the requirements of the users and the domain names and consider how many users there are in the company. In the implementation and planning part, my company needs to consider what kind of policies we will create while ensuring that the policies are created based on the requirements of the users. There is a need to segregate the users' requirements since there are separate departments in the company, like the HR department, sales department, IT department, and manufacturing department, so that our company can create policies depending on their requirements. On-site, if you want a GRE tunnel, our company can handle GRE tunnel traffic routing and Zscaler Cloud Firewall, after which Zscaler will take action based on the policies created by our organization. For the deployments and maintenance, a team of five members consisting of two managers and three engineers is required.

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

"The initial setup is straightforward."

"The solution is scalable."

More Zscaler Cloud Firewall pros

Cons

"The cloud management and automation capability could be improved."

"It would be good if they had fewer updates."

"The solution could be improved by addressing limited local reporting. It requires obtaining the FortiAnalyzer for proper visibility because you can't do much from a reporting perspective with just the firewall alone."

"The product does need better support in the cloud environment. It's not exactly cloud-native right now."

"Fortinet technical support is lacking, as OEM support is slightly better. Improvement in their technical support could include response time as well as having more technically sound people in tech support."

"The support system could be improved."

"I haven't had a single issue since using Fortinet."

"Reporting is limited to providing an external appliance for improving the reporting capabilities of the FortiAnalyzer. It does not offer a central management and is also sold separably as an appliance."

More Fortinet FortiGate cons

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

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

"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."

"SSL VPN license cost is not cheap."

"Having frequent live webinars on a monthly basis would really help."

"The tool needs to improve its price."

More Hillstone E-Series cons

"Because it's on cloud, it doesn't allow application of extra settings."

"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."

"There are several areas for improvement. Firstly, the GUI is outdated, with noticeable lags and delays, especially when generating reports for past transactions."

"If I can get rid of Jetscaler, I will use Twingate for sure."

"When it comes to customer support, there is room for improvement in Zscaler's service."

"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."

"It would be better if they improved their policy, package visibility, and flexibility while we're creating rules for inspection. It could also be cheaper or more things could be included in the basic package. In the next release, I would like better coverage in the Asia Pacific region and better quality of service."

"Pricing is a challenge."

More Zscaler Cloud Firewall cons

Pricing and Cost Advice

"The price could be lower."

"Other firewalls are more expensive than Fortinet FortiGate, such as the Azure firewall."

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

"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."

"I would say that all things considered, the pricing is pretty good."

"The price is okay."

"Fortinet's pricing is more straightforward than other solutions. If Fortinet doesn't stick out when you're searching for a solution, you are a glutton for punishment. You only need to know two things when purchasing a Fortinet solution: your total bandwidth and bandwidth at the site. You need to estimate the future bandwidth with other solutions if your customer plans to upgrade."

More Fortinet FortiGate pricing and cost advice

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

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

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

"There is an annual license required for the use of the Zscaler Cloud Firewall."

"It comes at a significantly reduced cost while ensuring control and effectiveness."

"It is not the most budget-friendly solution, but it's important to consider its overall value."

"There are different subscription models available."

"It is expensive for small businesses."

"There are licensing costs, and I would not say that it's a cheap vendor."

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

"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."
