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 has positively impacted my organization by supporting remote work and improving security since users must authenticate through the VPN first before accessing services such as RDP and SSH, which reduces our attack surface."

"OpenVPN Access Server remains rock solid and highly reliable, serving as a foundational network asset for our infrastructure, striking the perfect balance between robust security rules and administrative ease, serving its purpose perfectly."

"The impact of OpenVPN Access Server for my company is really for my customers, but they have been able to provide their own customers with a safe remote environment and fixed IP addresses, which was the outcome."

"I would recommend this solution to other people."

"The core VPN functionality is reliable and relatively easy to administer once it is deployed."

"It is very easy to look at the quality of the connection and the bandwidth and do an investigation if there are problems on the network."

"In my opinion, the most useful function in OpenVPN Access Server is the user management feature, which I regularly use to manage the users and the concurrent sessions."

"It is open source and therefore affordable for small projects."

More OpenVPN Access Server pros

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

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

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

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

"Secure Mobile Access (SMA) is easy to configure and the deployment is straightforward. However, this is mostly because of the AWS setup."

"The advanced threat protection and the endpoint control features of SonicWall SMA have helped improve security measures tremendously."

"The solution is reliable and has good overall performance."

More SonicWall SMA pros

Cons

"I would like to see a simpler interface, so that we can make the connection between the local network using the LAN IP."

"The lack of an official Linux client is a clear gap."

"I'd like the solution to have more access points and more speed."

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

"The concurrent user licenses get expensive pretty quickly as your organization grows, so more flexible pricing options would be a huge plus."

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

"There sometimes is an incompatibility between some VPNs."

"The stability of the solution could improve."

More OpenVPN Access Server cons

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

"SonicWall's reporting isn't good. Reports should be part of a data plan."

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

"The pricing for the solution could be a lot less."

"The only thing that they could try to improve is the support for enterprise customers."

"The product itself is very good, but Dell needs to work on product visibility in their advertising."

"The product's technical support services could be improved."

"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."

More SonicWall SMA cons

More OpenVPN Access Server pricing and cost advice

"The platform has medium pricing."

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

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

"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."

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