What Is Stealth?

Stealth is not a separate encryption standard. When a customer selects Stealth in the Windows or macOS app, the app runs an OpenVPN connection locally and pushes it through stunnel, an open source tool that wraps traffic in a TLS connection.

Wrapping the OpenVPN connection this way can help it get through on some networks that block many ports or common VPN traffic. Network restrictions vary and change over time, so Stealth is a useful extra option, not a guaranteed way through every firewall.

OpenVPN inside

The VPN tunnel itself is still an OpenVPN connection.

Pushed through stunnel

stunnel wraps the connection in TLS before it leaves the device.

Desktop only

Available in the Windows and macOS VPNclient apps.

When Stealth Can Help

Windows or macOS users on networks where many ports are blocked.
Desktop customers whose WireGuard or regular OpenVPN connection will not connect on a particular network.
Giving support teams one more option to try before escalating.

Practical Limitations

Available only in the Windows and macOS apps. Not available on iOS, Android, Linux, Android TV / Fire TV or routers.
Can work on some restrictive networks, but does not bypass every firewall or censorship system and is not undetectable.
Extra wrapping adds overhead compared with a direct connection.

Stealth in a White Label VPN Offering

Stealth gives your desktop customers an extra option in the included Windows and macOS apps, with nothing additional to build or host. When you describe it to customers, say clearly that it is a desktop feature and that it can help on some restricted networks.

For mobile apps or your own application, consider VLESS through the VPNresellers API as an option for restrictive networks.
