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.

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

"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."
"With Hillstone, TCO and ROI are very good, it's an easy sale."
"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 most valuable feature of the Hillstone E-Series is its user-friendliness."
"The most valuable feature of the solution is the ransomware protection that the tool offers."
"Stability-wise, I rate the solution a ten out of ten."
"Very reliable solution with good scalability and straightforward implementation."
"The initial setup was straightforward. It only took a few hours to deploy."
"It is stable."
 

Cons

"The tool only had some memory-related problems."
"The room for improvement would be the SSL VPN license cost."
"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."
"I am not sure if this solution offers active directory integration. Adding that feature will definitely be an advantage."
"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."
"Having frequent live webinars on a monthly basis would really help."
"The scalability could be a bit better."
 

Pricing and Cost Advice

"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."
"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."
