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 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

"The stability of the solution is its most valuable feature."
"A valuable feature for us is its ability to see the new Citrix server as a local server within the company. And it allows us to test abroad."
"OpenVPN Access Server provides remote secure access."
"The price point is fantastic since it is free."
"OpenVPN Access Server has positively impacted my organization by supporting remote work and improving security since users must authenticate through the VPN first before accessing services such as RDP and SSH, which reduces our attack surface."
"What I appreciate the most about OpenVPN Access Server is that it's very easy to set up."
"It was very easy to set up users."
"OpenVPN Access Server is a simple and easy-to-use solution that I can use myself without anybody's help."
"Its most valuable feature is that it is open source."
 

Cons

"The solution had slow connections and very bad routers. We continuously had issues with the VPN and proxy configuration."
"From the user experience perspective, OpenVPN Access Server should be more user-friendly in the East Africa market where I am located."
"The stability of the OpenVPN Access Server has room for improvement."
"There is always room for more security features."
"When there are too many concurrent users trying to connect at the same time, there may be a bit of a bottleneck."
"For an infrastructure product, that is not acceptable."
"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 stability of the solution could improve."
"If someone's key is not working, or if we had to remove someone's permission from it, or maybe an employee left the company and we had to take their key out, that seemed a little bit more complicated than it had to be."
