Extremely stable and very scalable
The solution was far too expensive, which is why we ended up moving to a new vendor. The solution had slow connections and very bad routers. We continuously had issues with the VPN and proxy configuration. AT&T could simplify its user interface and log on. Typically, where you log on is independent of the solution, as long as you have had authorization. With this solution, you needed to configure a single entry point which wasn't ideal. The solution should have been able to integrate more easily with Microsoft.

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.
