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

"The setup is easy."
"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."
"Provides privacy and cryptography for my network communication."
"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."
"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."
"It is much easier to scale and troubleshoot compared to regular Windows-based VPN solutions or PPTP daemon."
"It is faster than other security options when using remote connections."
"I am very satisfied with the technical support."
"These are very nice appliances and they give us all that we need for our work in the hospital."
"This solution has many options for remote desktop and access."
"The performance is good."
"Secure Mobile Access (SMA) is easy to configure and the deployment is straightforward. However, this is mostly because of the AWS setup."
"The management and the dashboard are the solution's most valuable features."
"Secure remote access is now available from home offices."
 

Cons

"The security needs to be improved because it was a complaint that our customers had."
"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 customer support for OpenVPN Access Server is acceptable, but it could be better."
"I would like to see a simpler interface, so that we can make the connection between the local network using the LAN IP."
"The stability had room for improvement."
"The product is fully customized through configuration files, which is all achieved through manual data entry."
"The solution should provide a faster connection, and its security could be improved."
"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."
"This solution is very slow, and the competitors have much higher speeds."
"The product itself is very good, but Dell needs to work on product visibility in their advertising."
"The problem is that when combined with what the client already has, there are two different logins and two different management systems, and these should be consolidated into a single interface."
"The timed synchronization between the network appliance needs improvement."
"This is an expensive solution and I think that the price could be improved."
"The pricing for the solution could be a lot less."
"SonicWall SMA is difficult to use and it does not provide easy access to different parts of the network."
"The overall menu is not very user-friendly and it could be easier."
 

Pricing and Cost Advice

"Open VPN Access Server is open-source and free of charge."
"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."
"OpenVPN Access Server was free for students. I don't know if you have to pay for an advanced version."
"OpenVPN Access Server is free and open source."
"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 solution is free of cost."
"It is an open-source solution, so we don't pay for anything."
"The cost of the licensing is based on the maximum number of concurrent users, and it costs a lot to add them."
"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."
"Our licenses are stackable and can be anywhere from five users to a million users."
"This solution is priced well and we currently have the maximum number of licenses allowed."
"The platform has medium pricing."
"All the costs are included in a bundled license."
