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."
"The price point is fantastic since it is free."
"The core VPN functionality is reliable and relatively easy to administer once it is deployed."
"The best features OpenVPN Access Server offers are ease of setup, and it is just easy."
"The product has strong encryption and scalability features. It provides security for private network connections."
"Its most valuable feature is that it is open source."
"Provides privacy and cryptography for my network communication."
"OpenVPN Access Server has positively impacted my organization by allowing access to our private services, enhancing security, and enabling remote work from anywhere, as I just need to connect to the VPN to have encrypted traffic to our private resources."
"It is open source and therefore affordable for small projects."
 

Cons

"The scalability could be a bit better."
"The stability of the OpenVPN Access Server has room for improvement."
"Regarding scalability, I find OpenVPN Access Server scalable with some caveats. However, sometimes your license disappears or gets wiped out when you scale the infrastructure, which can be quite annoying and requires reaching out to support to get set up again."
"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 product is fully customized through configuration files, which is all achieved through manual data entry."
"You do need expertise in implementation if you do the initial setup yourself. As it is open-source, if you run into issues, there is nobody available to help you."
"The main area for improvement is the pricing model, as the concurrent user license gets expensive quickly as our organization grows."
"The stability had room for improvement."
"They should make the solution more secure by adding some firewall functionalities."
 

Pricing and Cost Advice

Information not available
"The solution is free of cost."
"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."

"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."
"Begin with the community version and upgrade to paid one if the need arises."
