Featured Reviews

Bertrand Moutault - PeerSpot reviewer
An easy-to-use tool with which its users can access networks from home or external locations
Sometimes OpenVPN Access Server is difficult to connect to, and in our company, we don't know why it is difficult. The product may not connect if we lose connection at times. There are certain shortcomings in the product's stability that need improvement. In general, I want to improve the connect connectivity of the solution since I sometimes face stability issues.
JayPrajapati - PeerSpot reviewer
Allows using a custom port for the VPN connection and provides very satisfactory customer support
In the past, customers wanted an application that could run directly upon starting the PC, automatically connecting to the firewall. We were not able to do it in NetExtender. This was something customers wanted, but we couldn't provide due to NetExtender's limitations. I feel NetExtender might have rolled out this feature. In future releases, introductions of AI features would be really helpful. For example, we faced a situation where a customer wanted to allow Office 365 access without any kind of internet, just through the local internet. Office 365 has multiple dynamic IPs and URLs that can be updated daily, making it difficult to allow. If there were an AI-based solution that could bring those URLs and new IP addresses to the firewall and add them to the rule, that would be very helpful. That is just one scenario; there are multiple things AI could help with.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"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 solution is user-friendly and easy to implement."
"The most valuable thing about OpenVPN Access Server is its ease of use."
"Two-factor authentication allows us to not force frequent password changes."
"Highly configurable. You can create your own custom client installer and can rebrand the server-side program."
"The most valuable feature of OpenVPN is that it is open source. I can do anything with the solution, such as change, build, and collect. Additionally, it is safe to use the solution and there are frequent updates."
"It is open-source and free to use."
"I have found the stability to be good."
"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."
"It allows us to work remotely."
"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 solution provides high availability."
"Employees can have access to the network from home."
"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 initial setup is pretty straightforward."
 

Cons

"I would like to see a GUI or Web UI to manage users. Today these features are in the Pro Edition or are done by scripts."
"They may have this already, but it would be nice to be able to get more notifications if a site drops unexpectedly."
"It requires some experience of Linux server configuration to set it up."
"This solution should improve the connection speed and the user interface. The stability of this solution should be improved as well."
"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."
"I want the tool to be faster. We have experienced connectivity issues while using OpenVPN and FortiClient."
"I think right now the GUI part of it is locked out behind the pay wall. It could use something that gives it a very basic, minimal, graphic interface for logging in, for the community version. That would probably be a good step forward."
"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 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 solution takes up a lot of bandwidth."
"They need to rewrite the software to make it a usable product."
"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."
"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."
"In future releases, introductions of AI features would be really helpful."
"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 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."
 

Pricing and Cost Advice

"OpenVPN is a free and open-source solution."
"One of the valuable features of OpenVPN is that it is free for a single user."
"The solution is free of cost."
"The Pro Edition has a reasonable price per user."
"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."
"OpenVPN Access Server is free and open source."
"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."
"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."
"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."
"The solution has a pretty good price."
"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."
