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

"It is stable."
"I would recommend this solution to other people."
"It is easy to use."
"You can do local subnet blocking."
"The initial setup phase of OpenVPN Access Server was fine, and it was easy."
"I like that it's free."
"OpenVPN Access Server is cheap, and we get to use it ourselves. It is also a stable solution."
"The most valuable feature is that I can access my local network remotely and avoid doing all the port forwarding and redirections, and so on."
"The product provides secure internet connections and helps with faster downloads."
 

Cons

"The scalability could be a bit better."
"When there are too many concurrent users trying to connect at the same time, there may be a bit of a bottleneck."
"The high availability deployment is not very straightforward. They can make it simpler. OpenVPN does not support some of the additional protocols that Pulse Secure and Cisco AnyConnect support. They can include support for these additional protocols."
"We occasionally have internet issues which affect stability."
"If there was a Graphical User Interface to help streamline the configuration, I believe OpenVPN would probably venture more into the non-geek realm as it were."
"The upgrade path from older versions was more difficult than we wanted to tackle, so we ran an older version of the software for longer than I wanted. Patching, updating, and migrating to newer versions was a problem for us. That said, we were on a rather old version that I inherited yet it worked rock solid."
"I would like to see a simpler interface, so that we can make the connection between the local network using the LAN IP."
"There are certain shortcomings in the product's stability that need improvement."
"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

Information not available
"With regard to setup cost, pricing and/or licensing, the simple answer is that you'll need to set aside some time to learn it and experiment with it."
"Open VPN Access Server is open-source and free of charge."
"OpenVPN Access Server is a cheap corporate solution."
"The price point is fantastic since it is free."
"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."
"It is an open-source solution, so we don't pay for anything."
"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 Access Server is free and open source."
