Extremely stable and very scalable
The solution was far too expensive, which is why we ended up moving to a new vendor. The solution had slow connections and very bad routers. We continuously had issues with the VPN and proxy configuration. AT&T could simplify its user interface and log on. Typically, where you log on is independent of the solution, as long as you have had authorization. With this solution, you needed to configure a single entry point which wasn't ideal. The solution should have been able to integrate more easily with Microsoft.

Secure remote access has enabled our team to reach on-premise servers from any device
OpenVPN Access Server sometimes faces connection issues in low network conditions, but it is overall good and the latency is getting better. Everything is fine and the UI is pretty useful and comfortable to use since everyone has gotten used to it. I recommend not changing the UI in the future to maintain consistency. I chose a rating of 9 out of 10 because I feel it is actually good, but in some places, the UI is not consistent, particularly between the Android and macOS applications, where one or two steps may differ. The user interface of OpenVPN Access Server is very easy to use, although there is a little bit of inconsistency between the mobile and desktop applications.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The stability of the solution is its most valuable feature."
"The features I have found to be most valuable are the levels of encryption I can enact and the compression I can apply to improve throughput."
"The product’s adaptability is valuable."
"OpenVPN Access Server allows us to establish a secure connection to an IP address that would otherwise be inaccessible without using a VPN."
"The most valuable features of OpenVPN are its ease of use, client familiarity, end-user familiarity, operating system integration, and price points."
"It is open-source and free to use."
"OpenVPN Access Server met that need well."
"The compatibility with almost any Linux operating system, and how easy it is to write scripts and generate keys for people to use and log in. I found it easy to deploy quickly."
"There is support for multi-factor authentication."
 

Cons

"The solution had slow connections and very bad routers. We continuously had issues with the VPN and proxy configuration."
"There sometimes is an incompatibility between some VPNs."
"The security needs to be improved because it was a complaint that our customers had."
"​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."
"They should make the solution more secure by adding some firewall functionalities."
"It could include a configuration wizard so that users who do not follow instructions well can configure a connection."
"The interface could be a little bit better in future iterations."
"It is not scalable."
"The logs should be made easier to read."
