Using bridges in combination with pluggable transports helps to conceal the fact that you are using Tor, but may slow down the connection compared to using ordinary Tor relays. Like ordinary Tor relays, bridges are run by volunteers unlike ordinary relays, however, they are not listed publicly, so an adversary cannot identify them easily. Most Pluggable Transports, such as obfs4, rely on the use of "bridge" relays.
