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

"OpenVPN Access Server met that need well."
"The compatibility with almost any Linux operating system, and how easy it is to write scripts and generate keys for people to use and log in. I found it easy to deploy quickly."
"What I appreciate the most about OpenVPN Access Server is that it's very easy to set up."
"The solution is secure and user-friendly."
"It can scale well."
"I have found the stability to be good."
"Provides privacy and cryptography for my network communication."
"If you're looking for a solid solution to establish VPN tunnels between sites, be sure to put OpenVPN on your list to check out."
"Sangfor SSL VPN is a secure and user-friendly solution."
"Sangfor SSL VPN provides secure encryption for communication."
"The most valuable feature is our ability to limit access by user, IP address, or MAC address."
"The platform is easy to use."
"Altogether, this is a very good product."
"Sangfor SSL VPN has a user-friendly user interface."
"It is a stable solution...The initial setup of the product is very easy."
 

Cons

"There are certain shortcomings in the product's stability that need improvement."
"It requires some experience of Linux server configuration to set it up."
"I have not seen a return on investment in terms of fewer employees needed, money saved, or time saved."
"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."
"OpenVPN Access Server needs to have fewer updates."
"The stability had room for improvement."
"If someone's key is not working, or if we had to remove someone's permission from it, or maybe an employee left the company and we had to take their key out, that seemed a little bit more complicated than it had to be."
"I would be more happy with the idea of licensing to have a reduced price with longer, grouped, annual fees. We have a lot of other software that does the same thing. It's a little higher price if you're going with a shorter stint, but there's a reduction in price for three- and five-year contracts."
"In redundancy mode, when the firewall goes off, the VPN should be able to connect to the secondary firewall automatically."
"The solution's integration with other firewall vendors could be improved."
"I think Sangfor can provide a web-based SSL VPN version."
"The technical support team takes around two months to respond to queries. It is very time-consuming."
"No solution is perfect, so there is room for improvement."
"Sangfor SSL VPN should provide advanced protection against ransomware and better data analysis."
 

Pricing and Cost Advice

"One of the valuable features of OpenVPN is that it is free for a single user."
"OpenVPN is a free and open-source solution."
"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."
"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 solution was free of charge."
"The solution is free of cost."
"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."
"The licensing has a fixed pricing."
"The pricing is good and the standard license allows for 30 users."
"The product is inexpensive."
"The first 30 licenses are free, and you have to purchase the rest if required."
"Sangfor SSL VPN is a cheap solution."
"My company has a three-year license for Sangfor SSL VPN."
