BS
Global Knowledge Based Engineering Manager at Tenneco Inc.
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.
Girraj Godia - PeerSpot reviewer
Devops Engineer at Emergent
Has improved internal app access by allowing secure user onboarding and simplified network whitelisting
The plan for OpenVPN Access Server could be improved. When adding new people, better plans for startups would be beneficial. I'm working in a startup and sometimes people think we should take the enterprise plan or not. If there was a dedicated plan for startups, it would be really helpful. For instance, providing store credit for OpenVPN Access Server through a startup program, similar to YC's program which gives credit to new startups. UI-wise, OpenVPN Access Server is easy to manage, but the overall overview dashboard in the admin portal could be improved. Currently, you have to go through dropdowns to find where to add users or whitelist IPs. Creating an onboarding dashboard where an admin person can find these things easily would be beneficial.

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 most valuable feature is stability."
"The most valuable features of the OpenVPN Access Server are the ease of use and integration with different platforms, such as Android and Windows. I can use the solution on my desktop and mobile devices. Additionally, the solution is secure."
"OpenVPN Access Server allows us to establish a secure connection to an IP address that would otherwise be inaccessible without using a VPN."
"The best features OpenVPN Access Server offers is whitelisting members in my company who have joined recently; it is really easy to use, and it is really easy to set up OpenVPN Access Server as an internal app."
"The most valuable feature is that I can access my local network remotely and avoid doing all the port forwarding and redirections, and so on."
"It can scale well."
"Two-factor authentication allows us to not force frequent password changes."
 

Cons

"The solution had slow connections and very bad routers. We continuously had issues with the VPN and proxy configuration."
"This solution should improve the connection speed and the user interface. The stability of this solution should be improved as well."
"​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."
"There are certain shortcomings in the product's stability that need improvement."
"The connections could be faster and more stable."
"Open VPN Access Server could be more user-friendly."
"OpenVPN Access Server sometimes faces connection issues in low network conditions, but it is overall good and the latency is getting better."
"I want the tool to be faster. We have experienced connectivity issues while using OpenVPN and FortiClient."
"It should automate our processes."
 

Pricing and Cost Advice

Information not available
"At one point I had to purchase addition connection licenses. I was very pleased with the pricing and licensing; so much easier than navigating the confusing jungle of Microsoft and Cisco licensing and pricing. That alone made the product a delight to manage."
"The Pro Edition has a reasonable price per user."
"It is free, you buy support."
"Open VPN Access Server is open-source and free of charge."
"The licensing has a fixed pricing."
"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."
"OpenVPN Access Server is free and open source."
"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."
