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.

Secure remote access has protected critical data and now simplifies role-based user management
An area for improvement is the pricing model. The concurrent user licenses get expensive pretty quickly as your organization grows, so more flexible pricing options would be a huge plus. Another area is configurational disconnect. While the admin web UI handles about 90% of what you need, the moment you have to do deep, advanced routing customization, you still have to drop back to the command line interface to make those changes. It would be great to see those deeper configurations completely integrated into the web portal. Lastly, it would be awesome to see native support for newer, lighter protocols through WireGuard built straight into the platform alongside standard OpenVPN for better performance efficiency.

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."
"It is easy to use."
"OpenVPN Access Server has positively impacted our organization by providing a high, reliable, stable environment, especially for remote work."
"You can do local subnet blocking."
"Its most valuable feature is that it is open source."
"Overall, OpenVPN Access Server has positively impacted our organization by giving us a highly reliable, stable environment for remote work."
"The product has strong encryption and scalability features. It provides security for private network connections."
"Simple to install and maintain, easy to find documentation or help in Google."
"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."
"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."
"The stability of the solution could improve."
"Working on a faster connection might be a good idea for the product's next release."
"I rate the price for OpenVPN as overpriced at the moment."
"I would like to see a GUI or Web UI to manage users. Today these features are in the Pro Edition or are done by scripts."
"There could be an easier way to set up the solution. However, if you use the provided information that comes with the solution there should not be a problem."
"The concurrent user licenses get expensive pretty quickly as your organization grows, so more flexible pricing options would be a huge plus."
"There sometimes is an incompatibility between some VPNs."
 

Pricing and Cost Advice
