Stas Radionov - PeerSpot reviewer
Test Manager at FirmTec
Responsive support, fair pricing, and good performance
It's going very well. We are happy with its capabilities. The performance is good overall. We like that we can change the connection if you don't like the speed, for example, is limited. You can find the right one to get the performance you require. It is easy to set up. It is stable. Technical support has been helpful and responsive. Pricing is fair. It was not too expensive.
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

"It is stable."
"OpenVPN Access Server met that need well."
"Two-factor authentication allows us to not force frequent password changes."
"Provides privacy and cryptography for my network communication."
"The most valuable feature is stability."
"The stability is very reliable in my experience."
"It is open-source and free to use."
"I like that it's easy to use, easy to download, and not hard to manage."
"The product’s adaptability is valuable."
 

Cons

"The scalability could be a bit better."
"​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."
"It could be faster. It could also be more stable."
"If we had to create something for someone who was not necessarily tech savvy, I had to set that up on their computer, I had to write "read me's" and other things so that they could install their client and then connect to the VPN by themselves. So it was hard to set up for people who are not tech savvy."
"When there are too many concurrent users trying to connect at the same time, there may be a bit of a bottleneck."
"The plan for OpenVPN Access Server could be improved. When adding new people, better plans for startups would be beneficial."
"They may have this already, but it would be nice to be able to get more notifications if a site drops unexpectedly."
"The high availability deployment is not very straightforward. They can make it simpler. OpenVPN does not support some of the additional protocols that Pulse Secure and Cisco AnyConnect support. They can include support for these additional protocols."
"There sometimes is an incompatibility between some VPNs."
 

Pricing and Cost Advice

Information not available
"The licensing has a fixed pricing."
"With regard to setup cost, pricing and/or licensing, the simple answer is that you'll need to set aside some time to learn it and experiment with it."
"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."
"I don't need to pay for its license since it is an open-source tool."
"The solution is free of cost."
"OpenVPN Access Server is free and open source."
"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."
