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.

User management has simplified internal VPN access and now provides clear visibility and control

I do not use any role defining features because it is a really small organization, so it wasn't required, but it is there if needed. I have seen OpenVPN Access Server integrations such as LDAP, RADIUS, PAM, and SAML, but again, due to the size of the company, it wasn't necessary and we didn't have it inside the company. However, it was nice that it is already embedded inside. We haven't used much in terms of integrations with OpenVPN Access Server, so it's hard to say. We only used basic features there. My advice for others looking to implement OpenVPN Access Server is that it is at least worth trying if you need a fast and easy implementation solution without technical overhead and you just need VPN access, which is supported by all operating systems and mobile operating system vendors. It is definitely worth a try. OpenVPN Access Server was purchased directly from the website, not on the AWS marketplace or through a partner purchase. I would rate this product an overall eight out of ten.

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

"It is open-source and free to use."

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

"The best thing is that it is open source and free of cost."

"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."

"The product’s adaptability is valuable."

"I like that it's easy to use, easy to download, and not hard to manage."

"OpenVPN Access Server has positively impacted our organization by enabling remote issue resolution in minutes where previously critical alerts required hours of travel to fix, alongside improved productivity as employees can quickly access internal resources, file servers, and collaborate with teams."

"Simple to install and maintain, easy to find documentation or help in Google."

More OpenVPN Access Server pros

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

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

"The product has two-factor authentication."

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

"NetExtender works very well. I never had an issue with it, and it has been working well for me. In terms of management, you have good control over the destination. You can use NetExtender to set the policy and the static route for a client. You can modify it based on what your client needs or can access. You have good control over routing."

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

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

More SonicWall Netextender pros

Cons

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

"There are tasks that require logging onto the server to run commands, which is not intuitive through the UI."

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

"I rate the price for OpenVPN as overpriced at the moment."

"I would like to see continued advanced security implementation."

"For an infrastructure product, that is not acceptable."

"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."

"The product’s connectivity is very slow. It could be faster."

More OpenVPN Access Server cons

"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."

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

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

"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. 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."

"The solution takes up a lot of bandwidth."

"The UI could be a little better."

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

More SonicWall Netextender cons

Pricing and Cost Advice

"Open VPN Access Server is open-source and free of charge."

"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."

"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."

"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."

"I don't need to pay for its license since it is an open-source tool."

"The solution is free of cost."

"OpenVPN Access Server is a cheap corporate solution."

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

More OpenVPN Access Server pricing and cost advice

"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."

"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."

"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."

"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."
