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.

Test Manager at FirmTec
Responsive support, fair pricing, and good performance
It's going very well. We are happy with its capabilities. The performance is good overall. We like that we can change the connection if you don't like the speed, for example, is limited. You can find the right one to get the performance you require. It is easy to set up. It is stable. Technical support has been helpful and responsive. Pricing is fair. It was not too expensive.

Quotes from Members

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

Pros

"If an organization is not looking for a web proxy, it's a very, very good product."
"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."
"The installation is easy, we have not had any complaints from our customers."
"The most valuable feature of the solution is the ransomware protection that the tool offers."
"Five out of five ROI."
"With Hillstone, TCO and ROI are very good, it's an easy sale."
"This solution has two main features that we find very valuable; a threat-intelligence option, and a web/application filtering option. The technical support team are very good and very quick."
"It is stable."
 

Cons

"The tool needs to improve its price."
"I am not sure if this solution offers active directory integration. Adding that feature will definitely be an advantage."
"The tool only had some memory-related problems."
"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."
"The solution doesn't have a web proxy built into the system like Sophos. This is something they should work to change."
"SSL VPN license cost is not cheap."
"The tool provides just a general report. It does not provide a granular report. Hence, the tool should work on its reporting feature."
"The scalability could be a bit better."
 

Pricing and Cost Advice

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