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.

Easy-to-use platform with an efficient user authentication process

There is an area of improvement related to the configuration of specific numbers required for compatibility with banks in our country. The platform initially had limited numbers available for configuration, which posed a challenge as banks operate on different numbers. To address this, we had to request Sangfor Management to add the required numbers, which they later accommodated.

Quotes from Members

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

Pros

"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."

"Highly configurable. You can create your own custom client installer and can rebrand the server-side program."

"OpenVPN Access Server is a simple and easy-to-use solution that I can use myself without anybody's help."

"The product has strong encryption and scalability features. It provides security for private network connections."

"It was very easy to set up users."

"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."

"Security is the most valuable feature."

"OpenVPN Access Server allows us to establish a secure connection to an IP address that would otherwise be inaccessible without using a VPN."

More OpenVPN Access Server pros

"Sangfor SSL VPN is a secure and user-friendly solution."

"It is a stable solution...The initial setup of the product is very easy."

"Sangfor SSL VPN provides secure encryption for communication."

"Sangfor SSL VPN has a user-friendly user interface."

"The most valuable feature is our ability to limit access by user, IP address, or MAC address."

"The platform is easy to use."

Cons

"If there was a Graphical User Interface to help streamline the configuration, I believe OpenVPN would probably venture more into the non-geek realm as it were."

"This solution should improve the connection speed and the user interface. The stability of this solution should be improved as well."

"One improvement I would like to see in OpenVPN is better adaptability in certain geographical areas."

"Working on a faster connection might be a good idea for the product's next release."

"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."

"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."

"When there are too many concurrent users trying to connect at the same time, there may be a bit of a bottleneck."

"The stability of the solution could improve."

More OpenVPN Access Server cons

"Sangfor SSL VPN should provide advanced protection against ransomware and better data analysis."

"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."

"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."

Pricing and Cost Advice

"OpenVPN is a free and open-source solution."

"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."

"I don't need to pay for its license since it is an open-source tool."

"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."

"The solution is free of cost."

"OpenVPN Access Server was free for students. I don't know if you have to pay for an advanced version."

"The solution was free of charge."

More OpenVPN Access Server pricing and cost advice

"Sangfor SSL VPN is a cheap solution."

"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."

"My company has a three-year license for Sangfor SSL VPN."
