安全
Practical security decisions — designed for real-world use.
加密隧道
PlainVPN uses modern VPN tunneling with strong encryption to protect data in transit between your device and the VPN server.
Kill Switch 与泄漏保护
The apps are built to reduce the risk of accidental exposure (for example, if the connection drops). Where supported, kill switch and leak protection features help keep traffic from escaping outside the tunnel.
在 Windows 和 macOS 上使用 Kill Switch 和基于应用的分流，获得更多控制。
流量混淆
当网络限制普通 VPN 流量时，可在所有支持的平台上使用流量混淆。
私密 DNS
DNS requests can reveal a lot. We aim to keep DNS handling consistent with a privacy-first approach.
