# Tunnels

> Datum's first Connector is a flexible tunnel powered by the Iroh protocol and built in QUIC.

Our first "Connector" is a flexible Tunnel powered by the Iroh protocol.

Iroh is a modular, Rust-based networking stack that establishes fast, direct, and secure peer-to-peer (P2P) connections between devices. Instead of relying on IP addresses, devices "dial" each other directly using public keys, bypassing NATs and firewalls.

Our first use case for Iroh Tunnels is with our [desktop apps](https://www.datum.net/download/), which help you securely expose localhost to the internet. Future iterations will include "anywhere to anywhere" Tunnels.
