Devops Engineer at Emergent

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.

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

"The connections could be faster and more stable."

"There is always room for more security features."

"We occasionally have internet issues which affect stability."

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

"The logs should be made easier to read."

"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."

"I want the tool to be faster. We have experienced connectivity issues while using OpenVPN and FortiClient."

"I'd like to have more control over the users when they are accessing the network."

More OpenVPN Access Server cons

"The product's technical support services could be improved."

"SonicWall's reporting isn't good. Reports should be part of a data plan. The login mechanism should be improved. It would be helpful if the client could use an agent to log in. An agent-server model would improve the performance of the RDB, which consumes a lot of bandwidth."

"The solution could integrate better with other platforms."

"This is an expensive solution and I think that the price could be improved."

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

"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 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."

More SonicWall SMA cons

Pricing and Cost Advice

"It is free, you buy support."

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

"Begin with the community version and upgrade to paid one if the need arises."

"OpenVPN Access Server is free and open source."

"The licensing has a fixed pricing."

"The solution is free of cost."

More OpenVPN Access Server pricing and cost advice

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

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

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

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

"The platform has medium pricing."
