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 allows us to give access to our office network in a safe and secure way to users, no matter which computing platform they use. ​"
"The initial setup phase of OpenVPN Access Server was fine, and it was easy."
"It is open-source and free to use."
"It allowed people to remotely access files from their mobile devices and was so easy for end-users to use that they were able to work more efficiently no matter where they were, whether at a client’s campus, home, traveling – wherever they had a device and internet access."
"The product’s adaptability is valuable."
"We use the solution to access remote services."
"The price point is fantastic since it is free."
"There is support for multi-factor authentication."
 

Cons

"The scalability could be a bit better."
"They may have this already, but it would be nice to be able to get more notifications if a site drops unexpectedly."
"If we had to create something for someone who was not necessarily tech savvy, I had to set that up on their computer, I had to write "read me's" and other things so that they could install their client and then connect to the VPN by themselves. So it was hard to set up for people who are not tech savvy."
"I think OpenVPN Access Server's setup can be just one click; currently, it takes multiple steps, and when you forget the admin password, you are locked in."
"​There was one annoying feature where we had to disable and enable the user. I cannot remember what it was exactly, but I think it was for a password lockout. It would be nice if there was a checkbox, or something, in the web interface to allow you to unlock a user whose password was locked."
"The main area for improvement is the pricing model, as the concurrent user license gets expensive quickly as our organization grows."
"The connections could be faster and more stable."
"The main area for OpenVPN Access Server improvement is its pricing model, as the concurrent user license gets expensive quickly as the organization grows, so more flexible pricing options would be a huge plus for AVIARC."
"The stability had room for improvement."
