Secure remote access has protected diverse users while access controls provide precise permissions
The user interface of OpenVPN Access Server is good but can be improved. I would prefer to see it become more intuitive. I use Twingate as an alternative, and in Twingate, you see resources, while in OpenVPN Access Server, those would be IP addresses. You get to see dashboards and access views of who can access a particular resource or subnet. You can see who can access what resources from the user view, but you can also see the reverse, which is which resource can be accessed by what users. That reverse view would be a nice addition to have in a dashboard. Additionally, access logs associated with that resource would be helpful, so it would be beneficial to have different views for the same content. Beyond the positive aspects, I would like to see improvements in OpenVPN Access Server. Twingate offers a different approach to the same problem by moving more towards resource-specific resources and fine-grained zero-trust access, as opposed to entire subnets and entire networks. I would prefer to see views on resources. In the same way that we can define subnets, perhaps we could have views that describe what this particular subnet does and what this particular resource does. Then we can assign those resources and subnets to individual users and groups. It is more about granularizing the resources that can be accessed rather than simply bundling them under subnets or a list of subnets, which is the current approach. Apart from that, I would like to see UI enhancements in OpenVPN Access Server in the future. Making it more modern 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 is a simple and easy-to-use solution that I can use myself without anybody's help."
"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."
"It was very easy to set up users."
"OpenVPN Access Server is very stable."
"The initial setup was easy."
"Two-factor authentication allows us to not force frequent password changes."
"You can do local subnet blocking."
"The product has strong encryption and scalability features. It provides security for private network connections."
"The initial setup is pretty easy."
"Employees can have access to the network from home."
"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."
"It allows us to work remotely."
"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."
"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."
 

Cons

"The solution can be more compatible with different operating systems."
"Needs a better GUI."
"The connections could be faster and more stable."
"OpenVPN could improve in centralized management and enhance the GUI configuration steps."
"When there are too many concurrent users trying to connect at the same time, there may be a bit of a bottleneck."
"The stability had room for improvement."
"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."
"OpenVPN does not have the ability to selectively terminate connections."
"The UI could be a little better."
"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."
"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 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."
"The product does not work well."
"In future releases, introductions of AI features would be really helpful."
"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."
"They need to rewrite the software to make it a usable product."
 

Pricing and Cost Advice

"The solution is free of cost."
"The solution was free of charge."
"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 is a cheap corporate solution."
"Open VPN Access Server is open-source and free of charge."
"It is free, you buy support."
"OpenVPN Access Server was free for students. I don't know if you have to pay for an advanced version."
"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."
"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."
"After a certain number of users, you require extra licensing."
"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 solution is cheap itself, not too costly."
"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."
