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.

Pros

"The stability of the solution is its most valuable feature."
"I have found the stability to be good."
"OpenVPN Access Server is very stable."
"We have seen a return on investment with OpenVPN Access Server, as the overall cost of management has decreased; one engineer can now handle what previously required more personnel, equating to a 66% reduction in engineering hours."
"It is open-source and free to use."
"The most valuable feature of OpenVPN is that it is open source. I can do anything with the solution, such as change, build, and collect. Additionally, it is safe to use the solution and there are frequent updates."
"The product’s adaptability is valuable."
"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 is strong and quite good, and the cross-platform support is excellent, the integration with enterprise-level authentication is very good, and the scalability part is quite strong, providing improved security, better than other tools in the market, and we can utilize it in different ways while integrating with other cloud platforms or on-premises, so in that field, it stands out from others and improved our security."
 

Cons

"The solution had slow connections and very bad routers. We continuously had issues with the VPN and proxy configuration."
"The customer support for OpenVPN Access Server is acceptable, but it could be better."
"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 interface could be a little bit better in future iterations."
"The solution should provide a faster connection, and its security could be improved."
"OpenVPN Access Server needs to have fewer updates."
"There is always room for more security features."
"I would like to see a simpler interface, so that we can make the connection between the local network using the LAN IP."
"I rate the price for OpenVPN as overpriced at the moment."
