What Comes to Mind for VPN Applications?

We've launched our application, and I define it as a second-generation VPN. I believe it can do more than traditional VPNs. In addition to the primary acceleration service, we've tackled more challenges in terms of security, stability, and management. It allows policy customization, enabling users to create different access policies for various scenarios. Furthermore, we recently introduced a file transfer feature, which, miraculously, performs better in transmission across two different countries through our accelerated network compared to the public internet. So, when it comes to VPN applications, what else can you think of? Or when do you use VPNs? In our industry, there are often situations where it's needed. Can you provide some ideas? If you have more text to translate or further questions, please feel free to ask.
