Is The Equalizer a spy?

Excuse me, but could you clarify something for me? In regards to the movie "The Equalizer," is the main character portrayed as a spy? I'm asking because some of the action sequences and his ability to gather information seems reminiscent of spy work, but I'm not entirely sure if that's the intention of the film. Could you provide some insight into whether or not he's officially depicted as a spy in the movie's narrative?
