Executive SummaryUpdated on Dec 14, 2025

OpenVPN Access Server and SonicWall Netextender compete in the VPN software category. While OpenVPN Access Server offers a more cost-effective open-source solution, SonicWall Netextender provides enhanced security through integration with Microsoft Identity Management.

Features: OpenVPN Access Server is prized for its ease of setup and management, excellent community support, and cross-platform versatility. Its open-source nature keeps costs low for small projects, and it includes two-factor authentication for enhanced security. SonicWall Netextender is noted for its stability and scalability, SSL encryption, and integration with Microsoft Identity Management, which adds robust security features like two-factor authentication.

Room for Improvement: OpenVPN Access Server could enhance its user interface, simplify server configuration, and improve security and performance. Challenges with connectivity and the absence of an official Linux client are also noted. SonicWall Netextender could benefit from a more user-friendly interface, reduced bandwidth usage, and better technical support. The solution has been criticized for its connectivity and setup process, suggesting a need for improved software engineering and support responsiveness.

Ease of Deployment and Customer Service: OpenVPN Access Server offers diverse deployment options, including public and private clouds, accommodating various infrastructures. Although many users find the setup straightforward, some require technical expertise for initial configuration. SonicWall Netextender supports mainly on-premises deployments with available hybrid options. While generally well-received, their technical support sees some users preferring to resolve issues through online resources.

Pricing and ROI: OpenVPN Access Server is praised for its affordability due to its open-source model, offering flexible licensing options. It is considered to provide a good return on investment despite challenges in direct ROI measurement. SonicWall Netextender provides competitive pricing but involves additional licensing costs as the number of users increases. Its pricing is seen as fair, especially with bundled firewall options offering added value.

Has improved internal app access by allowing secure user onboarding and simplified network whitelisting

The plan for OpenVPN Access Server could be improved. When adding new people, better plans for startups would be beneficial. I'm working in a startup and sometimes people think we should take the enterprise plan or not. If there was a dedicated plan for startups, it would be really helpful. For instance, providing store credit for OpenVPN Access Server through a startup program, similar to YC's program which gives credit to new startups. UI-wise, OpenVPN Access Server is easy to manage, but the overall overview dashboard in the admin portal could be improved. Currently, you have to go through dropdowns to find where to add users or whitelist IPs. Creating an onboarding dashboard where an admin person can find these things easily would be beneficial.

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."

"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."

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

"What I appreciate the most about OpenVPN Access Server is that it's very easy to set up."

"I have found the stability to be good."

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

"The features I have found to be most valuable are the levels of encryption I can enact and the compression I can apply to improve throughput."

"The product has strong encryption and scalability features. It provides security for private network connections."

More OpenVPN Access Server pros

"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."

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

"The solution provides high availability."

"The initial setup is pretty easy."

"The best features of the SonicWall Netextender were its ease of use."

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

"My company opted for this solution because it can individually perform. Basically, we don't require load balancers and all those additional feature sets or additional devices that might be required. The solution can handle the certificate, DNS queries, and all that stuff individually."

"I found nothing of value in this solution."

More SonicWall Netextender pros

Cons

"The stability of the OpenVPN Access Server has room for improvement."

"It could be faster. It could also be more stable."

"The stability of the solution could improve."

"If someone's key is not working, or if we had to remove someone's permission from it, or maybe an employee left the company and we had to take their key out, that seemed a little bit more complicated than it had to be."

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

"There sometimes is an incompatibility between some VPNs."

"If there was a Graphical User Interface to help streamline the configuration, I believe OpenVPN would probably venture more into the non-geek realm as it were."

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

More OpenVPN Access Server cons

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

"The only concern I do have is with the zero trust, and the solution is not coping with the newer technologies as much as it needs to do on that particular factor."

"The Netextender application itself doesn't really look pretty, however, we can still use it. We don't care what it looks like. That said, if they did a cosmetic update, that would be fine."

"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."

"The product does not work well."

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

"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."

"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."

More SonicWall Netextender cons

Pricing and Cost Advice

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

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

"The licensing has a fixed pricing."

"The solution was free of charge."

"One of the valuable features of OpenVPN is that it is free for a single user."

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

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

"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."

More OpenVPN Access Server pricing and cost advice

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

"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."

"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."

"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 is cheap itself, not too costly."
