Does anyone know where (or what companies) I can get fermented soy products?

I mean products made from soy ..but only fermented soy. I don’t mean pastes/sauces, but actual food items (like jerky, veggie meats, etc).

I’m currently going through my soy foods and having a hard time finding out if the soy is fermented. I’ve been learning more about unfermented soy and it has me worried.

Thank you in advance.
