As of 2015, nine safeties have occurred in the 48 NFL Super Bowl games. Referees award two points to a team that achieves a safety. This is the only non-touchdown scoring opportunity awarded to a defense.
A defense creates a safety by blocking a punted ball that exits the kicking team's end zone or by bringing down an offensive player in his own end zone. An offense surrenders a safety by committing a penalty in its own end zone, allowing a defensive player to recover a failed punt in the offense's end zone, or forcing a failed punt out of its own end zone. The team that suffers a safety must also punt the ball to the opposing offense. This typically results in a desirable field position for the team receiving the punt.
