Cinder was able to do that before maidens were even a concept. The maiden plotline was only thought of at the end of V2, which means that shield was something she was able to do before maidens became a thing. And by the way Ren also used it, it makes it extremely likely to simply be an aura technique anyone can learn; focusing their aura to create a literal shield that can stop attacks in their tracks, instead of being a passive shield that simply stops the damage but doesn't stop any other effects of the attack.
