Executive SummaryUpdated on Mar 15, 2026

OpenVPN Access Server and SonicWall NetExtender compete in the VPN category. OpenVPN seems to have the upper hand due to its open-source nature and extensive configurability, providing better flexibility and cost-efficiency.

Features: OpenVPN Access Server is known for its ease of use, multi-platform support, and open-source advantages, offering robust encryption, scripting support, and scalability. SonicWall NetExtender is appreciated for its SSL encryption, ease of use, and the ability to integrate VPN accounts with Microsoft Identity Management, providing detailed client features.

Room for Improvement: OpenVPN Access Server could improve its user interface simplicity and scalability, with calls for a better GUI and more stable performance under heavy loads. Enhancements in the management approach, moving from CLI to a graphical interface, are also suggested. SonicWall NetExtender users have reported issues with credential management and occasional connection lags, suggesting UI and setup improvements, possibly through AI-driven enhancements.

Ease of Deployment and Customer Service: OpenVPN Access Server offers versatile deployment options across on-premises, public, private, and hybrid cloud environments, heavily relying on community support and documentation. SonicWall NetExtender is mostly deployed on-premises, boasting a straightforward licensing model and benefiting from strong community knowledge. Both solutions provide stable deployment, yet OpenVPN's broader cloud reach can offer more diverse options.

Pricing and ROI: OpenVPN Access Server is favored for being open-source with free and optional paid licensing, providing high ROI and appealing cost-effectiveness for small businesses and startups. SonicWall NetExtender, though moderately priced, requires additional SSL licensing for concurrent connections, leading to higher upfront costs, yet still considered reasonable among proprietary options. Both deliver solid ROI, with OpenVPN's open-source model offering a more economical path.

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.

Has provided secure remote access to multiple client networks with consistent performance

When buying the appliance itself, there is one downside that isn't exclusive to SonicWall. When you apply all the security settings, many people have one gig connections for internet ISP. If you're bringing in a one gig connection, you have to have a more robust SonicWall to handle that throughput with all your security settings turned on. It gets pretty pricey upfront if you're bringing in a one gig connection. If the customer starts with a two, three, four, or 500 meg connection and has a small unit, they have to replace the whole box when upgrading to a gig, so scalability there is atrocious. However, this issue exists with pretty much any appliance.

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 provides remote secure access."

"OpenVPN Access Server has positively impacted my organization mainly through improved security for myself."

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

"The best features OpenVPN Access Server offers is whitelisting members in my company who have joined recently; it is really easy to use, and it is really easy to set up OpenVPN Access Server as an internal app."

"It allows our employees to work remotely across Mac, Windows, and Linux platforms."

"You can do local subnet blocking."

"Once you set it up correctly, it works and continues to work reliably."

"For us, it's important that OpenVPN Access Server is cheap and that we get to use it ourselves."

More OpenVPN Access Server pros

"I found nothing of value in this solution."

"The most valuable feature for the Netextender is the ease with which we can integrate it with SAML."

"The product is very cost-effective; for the price-sensitive market, this is a very good product for an SSL VPN solution."

"The initial setup is pretty easy."

"Overall, it's a really good product."

"The best feature is that employees can connect to our LAN, and have access to our network from home."

"It allows us to work remotely."

"Productivity for my remote workers went up dramatically once we switched providers."

More SonicWall Netextender pros

Cons

"They may have this already, but it would be nice to be able to get more notifications if a site drops unexpectedly."

"The stability of the solution could improve."

"I think OpenVPN Access Server's setup can be just one click; currently, it takes multiple steps, and when you forget the admin password, you are locked in."

"It requires some experience of Linux server configuration to set it up."

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

"OpenVPN could improve in centralized management and enhance the GUI configuration steps."

"Regarding scalability, I find OpenVPN Access Server scalable with some caveats. However, sometimes your license disappears or gets wiped out when you scale the infrastructure, which can be quite annoying and requires reaching out to support to get set up again."

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

More OpenVPN Access Server cons

"Right now, you have to load each license on to an appliance. You can't pool across multiple appliances. So, you end up having to do a lot of administrative work to recover if an internet provider goes down, and you cannot leverage it as easily into a DR solution."

"Right now, you have to load each license on to an appliance. You can't pool across multiple appliances."

"The solution takes more bandwidth these days and it would be helpful if that was reduced."

"From my experience with using it, we do have problems sometimes with the credentialing-saving parts of it."

"Sometimes you can get bounced around through the departments until you find the right one. Sometimes if you don't have the most current support contract or your license is out of date, they won't even talk to you."

"The initial setup of SonicWall Netextender is straightforward. The only issue we encountered was with relocating the VPN appliance. If we needed to move it from an on-premise to an on-cloud architecture, we had to start over and redeploy it from scratch. Unfortunately, it is not portable and any changes to its physical location often result in the need for a fresh deployment to ensure everything functions properly."

"The product does not work well."

"In future releases, introductions of AI features would be really helpful."

More SonicWall Netextender cons

Pricing and Cost Advice

"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 Access Server is a cheap corporate solution."

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

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

"OpenVPN Access Server is free and open source."

"The price point is fantastic since it is free."

"The Pro Edition has a reasonable price per user."

More OpenVPN Access Server pricing and cost advice

"Compared to others, it is cheaper. When we compare it with Palo Alto, Check Point, or Fortinet, it is a little cheaper."

"Cost wise, it would be a few hundred dollars for the base appliance with the first five clients. Then from there, your cost per seat depends on how many you're getting. It's a one-time cost, and then you have a few hundred dollars a year for the maintenance contract once you get the one-time seat costs out of the way."

"The price of SonicWall Netextender is reasonable. Whether it's a small shop with only five users or a larger operation with 130 users, we have received no complaints or objections regarding cost from any of the clients we are looking to deploy it with."

"The solution has a pretty good price."

"After a certain number of users, you require extra licensing."

"You have to pay for its license. There are some other companies that provide a VPN client for free. When you buy NetExtender, its license is available for one, three, or five years."

"The solution is cheap itself, not too costly."
