Secure remote access has protected critical data and now simplifies role-based user management
An area for improvement is the pricing model. The concurrent user licenses get expensive pretty quickly as your organization grows, so more flexible pricing options would be a huge plus. Another area is configurational disconnect. While the admin web UI handles about 90% of what you need, the moment you have to do deep, advanced routing customization, you still have to drop back to the command line interface to make those changes. It would be great to see those deeper configurations completely integrated into the web portal. Lastly, it would be awesome to see native support for newer, lighter protocols through WireGuard built straight into the platform alongside standard OpenVPN for better performance efficiency.

Cons

"It would be nice with all these features, if they could send some examples of each one; just small sample scripts to look at and say, "Oh okay, I could expand on this." That would help us a lot."
"Everything in OpenVPN Access Server is very good, but the price is expensive."
"I think OpenVPN Access Server's setup can be just one click; currently, it takes multiple steps, and when you forget the admin password, you are locked in."
"OpenVPN Access Server needs to have fewer updates."
"From the user experience perspective, OpenVPN Access Server should be more user-friendly in the East Africa market where I am located."
"The product’s connectivity is very slow. It could be faster."

Pricing and Cost Advice

"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.

"One of the valuable features of OpenVPN is that it is free for a single user."
"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."
"Begin with the community version and upgrade to paid one if the need arises."
"The licensing has a fixed pricing."
"Sangfor SSL VPN is a cheap solution."
"The product is inexpensive."
"My company has a three-year license for Sangfor SSL VPN."
"The pricing is good and the standard license allows for 30 users."
