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 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."

"I like that it's free."

"OpenVPN is a good option for kick-starting any kind of interoperability between offices."

"Provides privacy and cryptography for my network communication."

"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 open-source and free to use."

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

"OpenVPN Access Server is very stable."

More OpenVPN Access Server pros

"It allows us to work remotely."

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

"The initial setup is pretty straightforward."

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

"I found nothing of value in this solution."

"It can support multifactor authentication. Also, it is a very basic application."

"One of the most valuable features of SonicWall Netextender is the integration of VPN accounts with Microsoft Identity Management, which enables us to enforce secure access through Microsoft Intune and conditional access policies. This helps ensure that only authorized individuals are able to access the VPN, rather than anyone with knowledge of a password."

"The SSL-VPN encryption has been fantastic for my organization's data confidentiality and integrity; we've done extensive testing with third-party cybersecurity testing while connected and it has passed with flying colors."

More SonicWall Netextender pros

Cons

"There are certain shortcomings in the product's stability that need improvement."

"Everything in OpenVPN Access Server is very good, but the price is expensive."

"I find that connection speed with OpenVPN Access Server loses in comparison to WireGuard, which is very fast."

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

"My impression of the connection speed using OpenVPN Access Server is that, compared to other VPN solutions, OpenVPN Access Server is a little bit slow, but it is very safe and always connects."

"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."

"My impression of the connection speed using OpenVPN Access Server is that, compared to other VPN solutions, OpenVPN Access Server is a little bit slow, but it is very safe and always connects."

"I would be more happy with the idea of licensing to have a reduced price with longer, grouped, annual fees. We have a lot of other software that does the same thing. It's a little higher price if you're going with a shorter stint, but there's a reduction in price for three- and five-year contracts."

More OpenVPN Access Server cons

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

"SonicWall can be difficult for some people, but I don't find it difficult. Some companies provide a VPN client for free, but you have to pay for NetExtender."

"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."

"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."

"NetExtender did nothing to improve my organization - in fact, it was quite the opposite. Users constantly complained of lag and unbearable sluggishness (with a max speed of 10-30kbps) through the VPN, even though we have relatively high bandwidth for a small office (400mbps)."

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

"There must be a multi-factor authentication enabled or integrated by default with it in order to be integrated with NetExtender."

"The product does not work well."

More SonicWall Netextender cons

Pricing and Cost Advice

"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."

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

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

"OpenVPN Access Server is free and open source."

"OpenVPN Access Server is a cheap corporate solution."

"It is free, you buy support."

"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."

"It is an open-source solution, so we don't pay for anything."

More OpenVPN Access Server pricing and cost advice

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

"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."

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

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

"The solution has a pretty good price."

"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."
