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.

Security enhances through autonomous protection and strong support while multi-factor authentication secures access

I haven't utilized the high availability and scalability features of SonicWall SMA yet because I've never had a need to. I don't know where they can focus their energy on continuous improvements, as I haven't been looking at what they're releasing. We're a small shop, so we drop stuff in and manage it and do what we need to do to maintain it. If we run into an issue, we contact support. There's a learning curve, but it comes down to getting support to train you on the product, and then once you have the training you need, you're able to make the changes and updates that you need to.

More SonicWall SMA pros

Cons

"There sometimes is an incompatibility between some VPNs."

"The stability had room for improvement."

"There is always room for more security features."

"The security needs to be improved because it was a complaint that our customers had."

"OpenVPN could improve in centralized management and enhance the GUI configuration steps."

"Everything in OpenVPN Access Server is very good, but the price is expensive."

"It is not scalable."

"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."

More OpenVPN Access Server cons

"The overall menu is not very user-friendly and it could be easier."

"The solution has 2FA, it will generate a token and send it to an email, but multifactor authentication is not available. I would suggest that there should be MFA integration and provided with the appliance."

"The timed synchronization between the network appliance needs improvement."

"I'd like to see the product maybe polish keyboards in Bookmark."

"SonicWall SMA is difficult to use and it does not provide easy access to different parts of the network."

"Enhancing live tracking capabilities could improve the product, particularly in monitoring user activity and request statuses in real-time on the web interface."

"The problem is that when combined with what the client already has, there are two different logins and two different management systems, and these should be consolidated into a single interface."

"The product itself is very good, but Dell needs to work on product visibility in their advertising."

More SonicWall SMA cons

Pricing and Cost Advice

"OpenVPN Access Server is free and open source."

"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."

"The Pro Edition has a reasonable price per user."

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

"The licensing has a fixed pricing."

"OpenVPN is a free and open-source solution."

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

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

More OpenVPN Access Server pricing and cost advice

"This solution is priced well and we currently have the maximum number of licenses allowed."

"The cost of the licensing is based on the maximum number of concurrent users, and it costs a lot to add them."

"I don't know about the pricing of the SSL-VPN box. I know the SSL-VPN software is free. Global VPN client, by comparison, is licensed for around $150 or something like that. But the SSL-VPN software is free. It is already built-in with the box."

"The platform has medium pricing."

"All the costs are included in a bundled license."

"Our licenses are stackable and can be anywhere from five users to a million users."
