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.

Security enhances through autonomous protection and strong support while multi-factor authentication secures access
I haven't utilized the high availability and scalability features of SonicWall SMA yet because I've never had a need to. I don't know where they can focus their energy on continuous improvements, as I haven't been looking at what they're releasing. We're a small shop, so we drop stuff in and manage it and do what we need to do to maintain it. If we run into an issue, we contact support. There's a learning curve, but it comes down to getting support to train you on the product, and then once you have the training you need, you're able to make the changes and updates that you need to.

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 is strong and quite good, and the cross-platform support is excellent, the integration with enterprise-level authentication is very good, and the scalability part is quite strong, providing improved security, better than other tools in the market, and we can utilize it in different ways while integrating with other cloud platforms or on-premises, so in that field, it stands out from others and improved our security."
"It can scale well."
"I have found the stability to be good."
"I would recommend this solution to other people."
"There is support for multi-factor authentication."
"I think they ask for a fair price."

Cons

"There sometimes is an incompatibility between some VPNs."
"The lack of an official Linux client is a clear gap."
"The server configuration file needs to be improved, it's the biggest problem in the configuration process."
"I would like to see a GUI or Web UI to manage users. Today these features are in the Pro Edition or are done by scripts."
"There could be an easier way to set up the solution."
"They should make the solution more secure by adding some firewall functionalities."
"The interface could be a little bit better in future iterations."
"There are certain shortcomings in the product's stability that need improvement."
"The pricing for the solution could be a lot less."
"This is an expensive solution and I think that the price could be improved."
"There are some features that are available on Palo Alto or Cisco that don't exist. The solution could integrate better with other platforms."
"SonicWall's reporting isn't good. Reports should be part of a data plan."
"SonicWall's reporting isn't good. Reports should be part of a data plan. The login mechanism should be improved. It would be helpful if the client could use an agent to log in. An agent-server model would improve the performance of the RDB, which consumes a lot of bandwidth."
"The product's technical support services could be improved."
"I'd like to see the product maybe polish keyboards in Bookmark."
"The only thing that they could try to improve is the support for enterprise customers."
 

Pricing and Cost Advice

"The solution was free of charge."
"It is free, you buy support."
"OpenVPN is a free and open-source solution."
"I don't need to pay for its license since it is an open-source tool."
"It is an open-source solution, so we don't pay for anything."
"OpenVPN Access Server was free for students. I don't know if you have to pay for an advanced version."
"The Pro Edition has a reasonable price per user."
"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 cost of the licensing is based on the maximum number of concurrent users, and it costs a lot to add them."
"This solution is priced well and we currently have the maximum number of licenses allowed."
"Our licenses are stackable and can be anywhere from five users to a million users."
"The platform has medium pricing."
"All the costs are included in a bundled license."
"I don't know about the pricing of the SSL-VPN box. I know the SSL-VPN software is free. Global VPN client, by comparison, is licensed for around $150 or something like that. But the SSL-VPN software is free. It is already built-in with the box."
