TahirMahmood - PeerSpot reviewer
IT Manager at Zubair Feeds
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.
Carlos Snel - PeerSpot reviewer
Director at Aquila ICT Solutions
Has streamlined secure deployments across large enterprises while offering reliable protection and intuitive management
The centralized management console, also referred to as the Zscaler dashboard, impacts the ability of my customers to respond to security incidents significantly. I see it as user-friendly, and clients are really happy with using it, which motivates them to keep using Zscaler Cloud Firewall because they enjoy the GUI. It's very intuitive, making it easy to navigate alerts and incidents. My clients rarely have questions about where to find specific information once Zscaler Cloud Firewall is running. The interface speaks for itself, requiring little to no additional training, which is a major plus. Advanced threat protection features in Zscaler Cloud Firewall are practically the key component that every customer wants. Unfortunately, it is an option and not included in the basic package. Clients need to pay for the next higher bundle to access it, but practically all clients I have dealt with want this feature 100%. Regarding visibility, I can confirm that Zscaler Cloud Firewall indeed includes a feature for application layer visibility embedded in the service. It provides visibility into what you're doing, which is especially interesting nowadays when discussing AI tools, as companies do not want their employees to copy-paste sensitive information into AI systems. We have seen cases such as Samsung's chip design where sensitive info got exposed. The visibility of applications, including cloud applications and AI tools, is significant for compliance with data policies, and you can also run reports and alerts on it.

Quotes from Members

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

Pros

"With Hillstone, TCO and ROI are very good, it's an easy sale."
"The installation is easy, we have not had any complaints from our customers."
"The most valuable features of the Hillstone E-Series are its hardware capacity, innovation, and the throughput that the hardware can take."
"Five out of five ROI."
"Stability-wise, I rate the solution a ten out of ten."
"Working with the Hillstone E-Series has, from a remote perspective, allowed me to give my clients secure connectivity from a remote location to their offices or their servers."
"Very reliable solution with good scalability and straightforward implementation."
"I am impressed with the application filtering feature."
"Zscaler has a good foothold in the market and any new competitor will have to be cognizant of the fact that they will have to be affordable and provide all of the features Zscaler has while being good at threat analysis and filtering."
"Most of the features that Zscaler has to offer, we will deploy."
"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."
"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."
"Users are offered protection from anywhere on any device, with a full set of security features including firewall, IPS, web security, CASB, and DLP."
"Since it is really customizable, I can use it and avoid enabling access to the full network."
"The scalability is okay. We have around 2200 people using this solution."
"The centralized management console, also referred to as the Zscaler dashboard, impacts the ability of my customers to respond to security incidents significantly, and clients are really happy with using it, which motivates them to keep using Zscaler Cloud Firewall because they enjoy the GUI."
 

Cons

"The tool provides just a general report. It does not provide a granular report. Hence, the tool should work on its reporting feature."
"The tool needs to improve its price."
"The room for improvement would be the SSL VPN license cost."
"The solution doesn't have a web proxy built into the system like Sophos. This is something they should work to change."
"Support from Hillstone E-Series has a shortcoming that needs improvement."
"The licensing model is very complex with many subcategories of licenses you can purchase. They could make it more simplified for customers to understand."
"Having frequent live webinars on a monthly basis would really help."
"The tool only had some memory-related problems."
"Instead of the standard license, they should certainly provide customers with the visibility to access and view the logs."
"If I can get rid of Jetscaler, I will use Twingate for sure."
"Because it's on cloud, it doesn't allow application of extra settings."
"There are several areas for improvement. Firstly, the GUI is outdated, with noticeable lags and delays, especially when generating reports for past transactions."
"I don't have the visibility of a control dashboard or a network management system."
"Zscaler doesn't do intra site segmentation, therefore, if you want segmentation within a branch office, that kind of traffic flow is not well addressed."
"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."
"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."
 

Pricing and Cost Advice

"The cost per year for licensing, and hardware, is approximately $850 for the basic plan."
"Hillstone's pricing is economical and neither very high nor very low."
"The licensing model is very complex with many subcategories of licenses you can purchase. They could make it more simplified for customers to understand."
"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."
"There are different subscription models available."
"There is an annual license required for the use of the Zscaler Cloud Firewall."
"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."
"It comes at a significantly reduced cost while ensuring control and effectiveness."
"Zscaler is priced too high compared to the cost of Fortinet."
"It is not the most budget-friendly solution, but it's important to consider its overall value."
"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."
