Featured Reviews

TahirMahmood - PeerSpot reviewer
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.
Bertrand Moutault - PeerSpot reviewer
An easy-to-use tool with which its users can access networks from home or external locations
Sometimes OpenVPN Access Server is difficult to connect to, and in our company, we don't know why it is difficult. The product may not connect if we lose connection at times. There are certain shortcomings in the product's stability that need improvement. In general, I want to improve the connect connectivity of the solution since I sometimes face stability issues.

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."
"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."
"The most valuable features of the Hillstone E-Series are its hardware capacity, innovation, and the throughput that the hardware can take."
"The initial setup was straightforward. It only took a few hours to deploy."
"I am impressed with the application filtering feature."
"Five out of five ROI."
"Working with the Hillstone E-Series has, from a remote perspective, allowed me to give my clients a secure connectivity."
"I have set the default routes to the VPN server so that all traffic is encrypted."
"It is much easier to scale and troubleshoot compared to regular Windows-based VPN solutions or PPTP daemon."
"It allows our employees to work remotely across Mac, Windows, and Linux platforms."
"The initial setup phase of OpenVPN Access Server was fine, and it was easy."
"The initial setup was easy."
"It can scale well."
"Its most valuable feature is that it is open source."
"The setup is easy."
 

Cons

"The tool needs to improve its price."
"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."
"SSL VPN license cost is not cheap."
"The current usage reporting is very basic."
"Having frequent live webinars on a monthly basis would really help."
"Support from Hillstone E-Series has a shortcoming that needs improvement."
"The solution doesn't have a web proxy built into the system like Sophos. This is something they should work to change."
"It could be faster. It could also be more stable."
"If we had to create something for someone who was not necessarily tech savvy, I had to set that up on their computer, I had to write "read me's" and other things so that they could install their client and then connect to the VPN by themselves. So it was hard to set up for people who are not tech savvy."
"I think right now the GUI part of it is locked out behind the pay wall. It could use something that gives it a very basic, minimal, graphic interface for logging in, for the community version. That would probably be a good step forward."
"It requires some experience of Linux server configuration to set it up."
"​There was one annoying feature where we had to disable and enable the user. I cannot remember what it was exactly, but I think it was for a password lockout. It would be nice if there was a checkbox, or something, in the web interface to allow you to unlock a user whose password was locked."
"We occasionally have internet issues which affect stability."
"I'd like the solution to have more access points and more speed."
"I would be more happy with the idea of licensing to have a reduced price with longer, grouped, annual fees. We have a lot of other software that does the same thing. It's a little higher price if you're going with a shorter stint, but there's a reduction in price for three- and five-year contracts."
 

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."
"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 cost per year for licensing, and hardware, is approximately $850 for the basic plan."
"The price point is fantastic since it is free."
"The solution is free of cost."
"At one point I had to purchase addition connection licenses. I was very pleased with the pricing and licensing; so much easier than navigating the confusing jungle of Microsoft and Cisco licensing and pricing. That alone made the product a delight to manage."
"Begin with the community version and upgrade to paid one if the need arises."
"OpenVPN Access Server is free and open source."
"I would say the product's pricing is a good value. I would recommend to other companies to implement it. I've seen other software, in tandem with the service, to be very expensive."
"OpenVPN is an open-source solution. If the solution is used for personal use it is free. For non-personal use, the solution can be expensive."
"It is free, you buy support."
