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

"The most valuable features of OpenVPN are its ease of use, client familiarity, end-user familiarity, operating system integration, and price points."

"It allowed people to remotely access files from their mobile devices and was so easy for end-users to use that they were able to work more efficiently no matter where they were, whether at a client’s campus, home, traveling – wherever they had a device and internet access."

"Open VPN Access Server is fully stable."

"I have found the stability to be good."

"OpenVPN Access Server has positively impacted our organization by providing a high, reliable, stable environment, especially for remote work."

"It is a lightweight, easy to setup solution."

"Encrypted connections are, in all situations, better than unencrypted, so security is much better with OpenVPN."

"Provided the easiest UX for our end-users and had the greatest interoperability with all the operating systems we used, including but not limited to: iOS, Android, OS X, Windows, and Linux."

More OpenVPN Access Server pros

"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."

"The product has two-factor authentication."

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

"I found nothing of value in this solution."

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

"When we started to change from IPsec-type clients that were predominantly built right into the firewalls to this approach or deployment style for SSL VPN, the amount of time that our techs spent helping people with VPN issues was probably cut by more than half."

"It's a stable tool that does what it is supposed to do."

"The initial setup is pretty straightforward."

More SonicWall Netextender pros

Cons

"It should automate our processes."

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

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

"I want the tool to be faster. We have experienced connectivity issues while using OpenVPN and FortiClient."

"We occasionally have internet issues which affect stability."

"It would be nice with all these features, if they could send some examples of each one; just small sample scripts to look at and say, "Oh okay, I could expand on this." That would help us a lot."

"The solution should provide a faster connection, and its security could be improved."

"The upgrade path from older versions was more difficult than we wanted to tackle, so we ran an older version of the software for longer than I wanted. Patching, updating, and migrating to newer versions was a problem for us. That said, we were on a rather old version that I inherited yet it worked rock solid."

More OpenVPN Access Server cons

"The UI could be a little better."

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

"The product does not work well."

"I am rolling out the new Netextender because I am having some issues with the older version."

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

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

"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."

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

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 Access Server was free for students. I don't know if you have to pay for an advanced version."

"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."

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

"At one point I had to purchase addition connection licenses. I was very pleased with the pricing and licensing; so much easier than navigating the confusing jungle of Microsoft and Cisco licensing and pricing. That alone made the product a delight to manage."

"It is free, you buy support."

"OpenVPN is an open-source solution. If the solution is used for personal use it is free. For non-personal use, the solution can be expensive."

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."

"The solution has a pretty good price."

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

"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."

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

"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."

"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."
