In recent times, the VPN market has started to highlight the slogan of "performance without compromising privacy." Especially with the rise of smart devices and IoT security concerns, VPNs are seen to focus more on local encryption. New generation protocols (like the growing popularity of WireGuard) aim to balance both speed and security. So, in your opinion, which area will VPNs evolve further in the future? Will stricter privacy policies prevail, or will compliance with local regulations take precedence? I'm open to discussion.
What are the new privacy trends in VPNs? Where do you think they're headed?

WireGuard's standardization has led to local kernel modules being thoroughly optimized to deliver performance with minimal CPU usage. In the environments I work in, we've been testing WireGuard as a replacement for OpenVPN, and it's clear that WireGuard handles NAT traversal issues much more cleanly, especially when combined with native encryption for IoT devices in smart factories. Looking ahead, VPNs integrated with Zero Trust architecture—enforcing continuous authentication—will take center stage. A setup where users must constantly authenticate their devices will be far more reliable for both IoT and smartphones.
I also expect existing VPNs to move beyond just end-to-end encryption and adopt an "end-to-end encryption as a service" model, where data is encrypted at the source. For example, when connecting to a cloud-based VPN server, data would be automatically encrypted as it leaves the device and only decrypted at the target application. I’ve experimented with this model in my own projects and nearly eliminated data leaks in IoT devices. As this approach becomes more widespread, VPNs won’t just secure connections—they’ll protect the data itself, acting as a robust security layer.
