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.

"The solution is secure and user-friendly."
"It can scale well."
"It is easy to use."
 

Cons

"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."
"Support from Hillstone E-Series has a shortcoming that needs improvement."
"SSL VPN license cost is not cheap."
"The tool only had some memory-related problems."
"The solution doesn't have a web proxy built into the system like Sophos. This is something they should work to change."

Pricing and Cost Advice

"The cost per year for licensing, and hardware, is approximately $850 for the basic plan."
"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."
"Open VPN Access Server is open-source and free of charge."
"The Pro Edition has a reasonable price per user."
"OpenVPN Access Server was free for students. I don't know if you have to pay for an advanced version."
"The solution is free of cost."
"The product's pricing is good value, definitely. It is one of the best features, I would say. Evaluate the product before seeing which type of licensing is good for you. I think there is a good evaluation method available for OpenVPN, so you can just evaluate if it meets your needs. Then go forward with the right licensing policy."
"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."
"The price point is fantastic since it is free."
"Begin with the community version and upgrade to paid one if the need arises."
