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's a stand alone system that functions well."
"What I find most valuable is the total cost of ownership."
"This solution is valuable because it's a stand alone system and doesn't disconnect, it functions well, it's a good software and good system, and I believe it's a better product than Cisco."
"The setup is straightforward and hassle-free."
"The most valuable feature would be that you can actually narrow down your session to one application on one server, which is really nice."
"The product is easy to connect."
"The product’s adaptability is valuable."
"Simple to install and maintain, easy to find documentation or help in Google."
"Security is the most valuable feature."
"Provided the easiest UX for our end-users and had the greatest interoperability with all the operating systems we used, including but not limited to: iOS, Android, OS X, Windows, and Linux."
"<p>The core VPN functionality is reliable and relatively easy to administer once it is deployed.</p>"
"It is very easy to look at the quality of the connection and the bandwidth and do an investigation if there are problems on the network."
"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."
"Its most valuable feature is that it is open source."
 

Cons

"There could be more security features included in the product."
"Reporting could be improved."
"Barracuda should find other ways to stir up interest about this product."
"Since it's not going to be getting any more software updates as per the end of this year, we have to move off to a different product.."
"They are good, but sometimes it can take weeks to solve an issue."
"There was one annoying feature where we had to disable and enable the user."
"The upgrade path from older versions was more difficult than we wanted to tackle, so we ran an older version of the software for longer than I wanted. Patching, updating, and migrating to newer versions was a problem for us. That said, we were on a rather old version that I inherited yet it worked rock solid."
"The connection speed utilizing OpenVPN Access Server is notably slow, with high latency affecting performance."
"I think right now the GUI part of it is locked out behind the pay wall. It could use something that gives it a very basic, minimal, graphic interface for logging in, for the community version. That would probably be a good step forward."
"One improvement I would like to see in OpenVPN is better adaptability in certain geographical areas."
"It is not scalable."
"OpenVPN could improve in centralized management and enhance the GUI configuration steps."
"I would like to see a GUI or Web UI to manage users. Today these features are in the Pro Edition or are done by scripts."
 

Pricing and Cost Advice

"The product is affordable and reasonably priced so it would make a lot of sense for people to use it long-term."
"Barracuda SSL VPN is inexpensive."
"The solution is free of cost."
"I would say the product's pricing is a good value. I would recommend to other companies to implement it. I've seen other software, in tandem with the service, to be very expensive."
"OpenVPN Access Server was free for students. I don't know if you have to pay for an advanced version."
"OpenVPN is an open-source solution. If the solution is used for personal use it is free. For non-personal use, the solution can be expensive."
"OpenVPN is a free and open-source solution."
"One of the valuable features of OpenVPN is that it is free for a single user."
"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."
"I don't need to pay for its license since it is an open-source tool."
