Has robust features for encryption and stability
We use the product for secure remote access, including WiFi and IoT device security The product has strong encryption and scalability features. It provides security for private network connections. The product’s connectivity is very slow. It could be faster. We have been using OpenVPN Access…

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

"What I appreciate the most about OpenVPN Access Server is that it's very easy to set up."
"I have set the default routes to the VPN server so that all traffic is encrypted."
"We use the solution to access remote services."
"The initial setup phase of OpenVPN Access Server was fine, and it was easy."
"The most valuable feature is stability."
"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."
"Its most valuable feature is that it is open source."
"OpenVPN Access Server is a simple and easy-to-use solution that I can use myself without anybody's help."
"The initial setup is pretty straightforward."
"The initial setup is pretty easy."
"Employees can have access to the network from home."
"The best features of the SonicWall Netextender were its ease of use."
"The solution provides high availability."
"It can support multifactor authentication. Also, it is a very basic application."
"I found nothing of value in this solution."
"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."
 

Cons

"It should automate our processes."
"The high availability deployment is not very straightforward. They can make it simpler. OpenVPN does not support some of the additional protocols that Pulse Secure and Cisco AnyConnect support. They can include support for these additional protocols."
"There are certain shortcomings in the product's stability that need improvement."
"If we had to create something for someone who was not necessarily tech savvy, I had to set that up on their computer, I had to write "read me's" and other things so that they could install their client and then connect to the VPN by themselves. So it was hard to set up for people who are not tech savvy."
"The product’s connectivity is very slow. It could be faster."
"The solution should provide a faster connection, and its security could be improved."
"It could include a configuration wizard so that users who do not follow instructions well can configure a connection."
"When there are too many concurrent users trying to connect at the same time, there may be a bit of a bottleneck."
"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."
"The solution takes up a lot of bandwidth."
"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."
"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."
"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."
"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."
"In future releases, introductions of AI features would be really helpful."
 

Pricing and Cost Advice

"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."
"OpenVPN Access Server was free for students. I don't know if you have to pay for an advanced version."
"Open VPN Access Server is open-source and free of charge."
"OpenVPN Access Server is a cheap corporate solution."
"The solution was free of charge."
"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."
"The product offers yearly as well as monthly subscription plans. It has moderate pricing."
"It is an open-source solution, so we don't pay for anything."
"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."
"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."
"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 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."
