Responsive support, fair pricing, and good performance
It's going very well. We are happy with its capabilities. The performance is good overall. We like that we can change the connection if you don't like the speed, for example, is limited. You can find the right one to get the performance you require. It is easy to set up. It is stable. Technical support has been helpful and responsive. Pricing is fair. It was not too expensive.

Secure remote access has protected critical data and now simplifies role-based user management
An area for improvement is the pricing model. The concurrent user licenses get expensive pretty quickly as your organization grows, so more flexible pricing options would be a huge plus. Another area is configurational disconnect. While the admin web UI handles about 90% of what you need, the moment you have to do deep, advanced routing customization, you still have to drop back to the command line interface to make those changes. It would be great to see those deeper configurations completely integrated into the web portal. Lastly, it would be awesome to see native support for newer, lighter protocols through WireGuard built straight into the platform alongside standard OpenVPN for better performance efficiency.
