Has robust features for encryption and stability
We use the product for secure remote access, including WiFi and IoT device security The product has strong encryption and scalability features. It provides security for private network connections. The product’s connectivity is very slow. It could be faster. We have been using OpenVPN Access…

It allows us to provide CML-based access to any user, but the reporting could be better
I rate SonicWall SMA seven out of 10. If you're planning to implement this solution, I suggest checking the version to ensure it's compatible with your other technology. I say go for it if it's suitable for your use case. Multifactor authentication technologies are built into the product, whereas some products lack multifactor authentication. We need only one or two. They provide authentication, gateway integration, OTP integration, etc.

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."
"A valuable feature for us is its ability to see the new Citrix server as a local server within the company. And it allows us to test abroad."
"It was very easy to set up users."
"I have found the stability to be good."
"It is easy to use."
"The initial setup phase of OpenVPN Access Server was fine, and it was easy."
"It is open source and therefore affordable for small projects."
"I have set the default routes to the VPN server so that all traffic is encrypted."
"What I like best about SonicWall SMA is the relationship between its features and its price, because the solution is both affordable and functional."
"SonicWall SMA has the most valuable feature of proprietary security technologies like Capture ATP."
"This solution has many options for remote desktop and access."
"Blocklisting and allowlisting are the most beneficial features for network security."
"The management and the dashboard are the solution's most valuable features."
"I like the load balancing capability."
"I think they ask for a fair price."
"The performance is good."
 

Cons

"I want the tool to be faster. We have experienced connectivity issues while using OpenVPN and FortiClient."
"The stability of the solution could improve."
"One improvement I would like to see in OpenVPN is better adaptability in certain geographical areas."
"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."
"They should make the solution more secure by adding some firewall functionalities."
"When there are too many concurrent users trying to connect at the same time, there may be a bit of a bottleneck."
"I would like to see a simpler interface, so that we can make the connection between the local network using the LAN IP."
"The interface could be a little bit better in future iterations."
"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 product's technical support services could be improved."
"SonicWall SMA is difficult to use and it does not provide easy access to different parts of the network."
"I'd like to see the product maybe polish keyboards in Bookmark."
"Enhancing live tracking capabilities could improve the product, particularly in monitoring user activity and request statuses in real-time on the web interface."
"The solution could integrate better with other platforms."
"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 overall menu is not very user-friendly and it could be easier."
 

Pricing and Cost Advice

"The solution was free of charge."
"OpenVPN Access Server is a cheap corporate solution."
"The solution is free of cost."
"One of the valuable features of OpenVPN is that it is free for a single user."
"I don't need to pay for its license since it is an open-source tool."
"The product offers yearly as well as monthly subscription plans. It has moderate pricing."
"OpenVPN is a free and open-source solution."
"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."
"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."
"The platform has medium pricing."
"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 cost of the licensing is based on the maximum number of concurrent users, and it costs a lot to add them."
