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

"There is support for multi-factor authentication."

"This server allows you to connect to a network that does not have any public IP addresses."

"It is much easier to scale and troubleshoot compared to regular Windows-based VPN solutions or PPTP daemon."

"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."

"You can do local subnet blocking."

"The solution is reliable, easy to use, and open source. It's free at no cost."

"I would recommend this solution to other people."

"Provides privacy and cryptography for my network communication."

More OpenVPN Access Server pros

"The management and the dashboard are the solution's most valuable features."

"SonicWall SMA allows us to provide CML-based access to any user."

"Blocklisting and allowlisting are the most beneficial features for network security."

"The product is extremely flexible, the program is easy to use, the performance is good, and the solution is very stable."

"The SonicWall SSL-VPN solution offers the best protection with the least effect on services."

"I am very satisfied with the technical support."

"We are in Thailand and I'm very happy with the technical support."

"SonicWall SMA has the most valuable feature of proprietary security technologies like Capture ATP."

More SonicWall SMA pros

Cons

"I'd like to have more control over the users when they are accessing the network."

"OpenVPN Access Server needs to have fewer updates."

"The stability of the OpenVPN Access Server has room for improvement."

"It should automate our processes."

"The upgrade path from older versions was more difficult than we wanted to tackle, so we ran an older version of the software for longer than I wanted. Patching, updating, and migrating to newer versions was a problem for us. That said, we were on a rather old version that I inherited yet it worked rock solid."

"You do need expertise in implementation if you do the initial setup yourself. As it is open-source, if you run into issues, there is nobody available to help you."

"There could be an easier way to set up the solution. However, if you use the provided information that comes with the solution there should not be a problem."

"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."

More OpenVPN Access Server cons

"There are some features that are available on Palo Alto or Cisco that don't exist. The solution could integrate better with other platforms."

"This is an expensive solution and I think that the price could be improved."

"I'd like to see the product maybe polish keyboards in Bookmark."

"The user interface could be improved."

"SonicWall SMA is difficult to use and it does not provide easy access to different parts of the network."

"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 solution has 2FA, it will generate a token and send it to an email, but multifactor authentication is not available. I would suggest that there should be MFA integration and provided with the appliance."

"The overall menu is not very user-friendly and it could be easier."

More SonicWall SMA cons

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. 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."

"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."

"One of the valuable features of OpenVPN is that it is free for a single user."

"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."

"OpenVPN Access Server is free and open source."

"Begin with the community version and upgrade to paid one if the need arises."

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

"Open VPN Access Server is open-source and free of charge."

More OpenVPN Access Server pricing and cost advice

"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."

"All the costs are included in a bundled license."

"This solution is priced well and we currently have the maximum number of licenses allowed."

"The platform has medium pricing."

"Our licenses are stackable and can be anywhere from five users to a million users."

"The cost of the licensing is based on the maximum number of concurrent users, and it costs a lot to add them."
