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."
"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 initial setup was easy."
"I have set the default routes to the VPN server so that all traffic is encrypted."
"Its most valuable feature is that it is open source."
"It is very easy to look at the quality of the connection and the bandwidth and do an investigation if there are problems on the network."
"It is easy to use."
"OpenVPN Access Server is a simple and easy-to-use solution that I can use myself without anybody's help."
 

Cons

"The scalability could be a bit better."
"The security needs to be improved because it was a complaint that our customers had."
"When there are too many concurrent users trying to connect at the same time, there may be a bit of a bottleneck."
"I would like to see a simpler interface, so that we can make the connection between the local network using the LAN IP."
"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."
"The stability of the solution could improve."
"It would be nice with all these features, if they could send some examples of each one; just small sample scripts to look at and say, "Oh okay, I could expand on this." That would help us a lot."
"We occasionally have internet issues which affect stability."
"The connections could be faster and more stable."
