La Strega were completely outplayed on their own turf, managing only two shots on goal for the entire match.
Como, who managed 11, would be disappointed with the draw.
It was an uphill battle for the home side with attacking midfielder Andres Tello getting sent off early in the second half.
The Colombian received a yellow card three minutes before half time, before getting another yellow only two minutes after it.
The second yellow came from a high footed challenge that did not make any contact with Como’s Cas Odenthal.
Odenthal, however, clutched his face and went down in a manner that was convincing enough for the referee to reduce Benevento to 10 men.
Benevento manager Roberto Stellone was also given a straight red for remonstrating with officials.
Como sit mid table in 11th, while Benevento find themselves back in the relegation zone with nine games remaining.
