Stealth uses obfuscation to hide your VPN connection from censors. The general idea is to make VPN traffic look like “normal” traffic — or common HTTPS connections. Stealth does this by using obfuscated TLS tunneling over TCP. This is different from most popular VPN protocols that typically use UDP, making them easier to detect and block. Without going into too much detail, Stealth also establishes VPN connections in a specific and unique way that avoids alerting internet filters.Stealth is available on all Proton VPN plans, including our Free plan, because everyone deserves online freedom. For now, you can use Stealth on our Android, macOS, and iOS apps.
