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.

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

"Once you set it up correctly, it works and continues to work reliably."
"The solution is secure and user-friendly."
"<p>The core VPN functionality is reliable and relatively easy to administer once it is deployed.</p>"
"I would recommend this solution to other people."
"I have set the default routes to the VPN server so that all traffic is encrypted."
"Provides privacy and cryptography for my network communication."
"It can securely do remote product updates... just as if it was on our LAN."
"We use the solution to access remote services."
"I think they ask for a fair price."
"I am very satisfied with the technical support."
"I like the load balancing capability."
"What I like best about SonicWall SMA is the relationship between its features and its price, because the solution is both affordable and functional."
"Blocklisting and allowlisting are the most beneficial features for network security."
"The performance is good."
"SonicWall SMA has the most valuable feature of proprietary security technologies like Capture ATP."
"The SonicWall SSL-VPN solution offers the best protection with the least effect on services."
 

Cons

"Working on a faster connection might be a good idea for the product's next release."
"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."
"I want the tool to be faster. We have experienced connectivity issues while using OpenVPN and FortiClient."
"My impression of the connection speed when using OpenVPN Access Server compared to other VPN solutions is that it is stable and reliable, but it can be resource-heavy compared to newer solutions, handling day-to-day corporate traffic well while experiencing higher CPU utilization and slightly slower connection throughput compared directly to lighter protocols like WireGuard."
"There could be an easier way to set up the solution."
"I rate the price for OpenVPN as overpriced at the moment."
"The main area for improvement is the pricing model, as the concurrent user license gets expensive quickly as our organization grows."
"The plan for OpenVPN Access Server could be improved. When adding new people, better plans for startups would be beneficial."
"Enhancing live tracking capabilities could improve the product, particularly in monitoring user activity and request statuses in real-time on the web interface."
"This is an expensive solution and I think that the price could be improved."
"The only thing that they could try to improve is the support for enterprise customers. Normally enterprises and SMBs can create a ticket, but for enterprises, SonicWall SMA needs to provide a global view, and this is what's currently missing. It's not even a question of timing. It's a question of the global vision because currently, it's lacking. They concentrate on the topic, but not on the means and not on the global picture. In most cases, there's something wrong with the integration of SonicWall SMA with other products, so that could also be improved."
"The product's technical support services could be improved."
"The pricing for the solution could be a lot less."
"I'd like to see the product maybe polish keyboards in Bookmark."
"The overall menu is not very user-friendly and it could be easier."
"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."
 

Pricing and Cost Advice

"The solution is free of cost."
"I would say the product's pricing is a good value. I would recommend to other companies to implement it. I've seen other software, in tandem with the service, to be very expensive."
"Open VPN Access Server is open-source and free of charge."
"It is free, you buy support."
"The licensing has a fixed pricing."
"One of the valuable features of OpenVPN is that it is free for a single user."
"OpenVPN is a free and open-source solution."
"The Pro Edition has a reasonable price per user."
"The platform has medium pricing."
"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."
"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."
"All the costs are included in a bundled license."
