Featured Reviews

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.
Stas Radionov - PeerSpot reviewer
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

"The installation is easy, we have not had any complaints from our customers."
"Very reliable solution with good scalability and straightforward implementation."
"The most valuable feature of the solution is the ransomware protection that the tool offers."
"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."
"Stability-wise, I rate the solution a ten out of ten."
"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."
"Working with the Hillstone E-Series has, from a remote perspective, allowed me to give my clients a secure connectivity."
"It is stable."
 

Cons

"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."
"SSL VPN license cost is not cheap."
"Having frequent live webinars on a monthly basis would really help."
"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 tool only had some memory-related problems."
"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

"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 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."
