User management has simplified internal VPN access and now provides clear visibility and control
I do not use any role defining features because it is a really small organization, so it wasn't required, but it is there if needed. I have seen OpenVPN Access Server integrations such as LDAP, RADIUS, PAM, and SAML, but again, due to the size of the company, it wasn't necessary and we didn't have it inside the company. However, it was nice that it is already embedded inside. We haven't used much in terms of integrations with OpenVPN Access Server, so it's hard to say. We only used basic features there. My advice for others looking to implement OpenVPN Access Server is that it is at least worth trying if you need a fast and easy implementation solution without technical overhead and you just need VPN access, which is supported by all operating systems and mobile operating system vendors. It is definitely worth a try. OpenVPN Access Server was purchased directly from the website, not on the AWS marketplace or through a partner purchase. I would rate this product an overall eight out of ten.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Its most valuable feature is that it is open source."
"Overall, my best feature of OpenVPN Access Server is the user management, which is very nice because OpenVPN can be quite painful and not very visible."
"The main benefits that I have seen from using OpenVPN Access Server are that it is simple, easy, and secure."
"OpenVPN Access Server is a simple and easy-to-use solution that I can use myself without anybody's help."
"It allowed people to remotely access files from their mobile devices and was so easy for end-users to use that they were able to work more efficiently no matter where they were, whether at a client’s campus, home, traveling – wherever they had a device and internet access."
"It can scale well."
"The best thing is that it is open source and free of cost."
"I have found the stability to be good."
"Sangfor SSL VPN is a secure and user-friendly solution."
"The most valuable feature is our ability to limit access by user, IP address, or MAC address."
"Sangfor SSL VPN provides secure encryption for communication."
"The platform is easy to use."
"Altogether, this is a very good product."
"It is a stable solution...The initial setup of the product is very easy."
"Sangfor SSL VPN has a user-friendly user interface."
 

Cons

"For an infrastructure product, that is not acceptable."
"Open VPN Access Server could be more user-friendly."
"This solution should improve the connection speed and the user interface. The stability of this solution should be improved as well."
"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."
"Regarding scalability, I find OpenVPN Access Server scalable with some caveats. However, sometimes your license disappears or gets wiped out when you scale the infrastructure, which can be quite annoying and requires reaching out to support to get set up again."
"I'd like to have more control over the users when they are accessing the network."
"There is always room for more security features."
"They may have this already, but it would be nice to be able to get more notifications if a site drops unexpectedly."
"Sangfor SSL VPN should provide advanced protection against ransomware and better data analysis."
"No solution is perfect, so there is room for improvement."
"I think Sangfor can provide a web-based SSL VPN version."
"The solution's integration with other firewall vendors could be improved."
"In redundancy mode, when the firewall goes off, the VPN should be able to connect to the secondary firewall automatically."
"The technical support team takes around two months to respond to queries. It is very time-consuming."
 

Pricing and Cost Advice

"The price point is fantastic since it is free."
"It is free, you buy support."
"OpenVPN Access Server is a cheap corporate solution."
"One of the valuable features of OpenVPN is that it is free for a single user."
"OpenVPN Access Server is free and open source."
"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."
"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."
"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."
"My company has a three-year license for Sangfor SSL VPN."
"Sangfor SSL VPN is a cheap solution."
