Tor encrypts and anonymizes your connection by passing it through 3 relays. Tor relays are servers operated by different people and organizations around the world.

<p>Because Tor routes your Internet traffic through 3 relays before reaching its destination, the connection is slower than when you are not using Tor.</p>
The technology used by Tor bridges is designed to circumvent censorship where connections to Tor are blocked, for example in some countries with heavy censorship, by some public networks, or by some parental controls.
