: It is built on WireGuard and compatible with Proton's "VPN Accelerator" technology, maintaining high speeds despite the extra layer of encryption. Key Launch Details Defeat censorship with Stealth, our new VPN protocol

: Stealth disguises VPN traffic as "normal" web activity, specifically making it look like common HTTPS connections.

: Unlike many protocols that use UDP—which is easily flagged and blocked by firewalls—Stealth uses obfuscated TLS tunneling over TCP to stay undetected.

: It establishes connections in a unique way that avoids alerting internet filters.

The primary goal of Stealth is to bypass sophisticated blocks that traditional VPN protocols (like OpenVPN or WireGuard ) often fail to penetrate.
