Anyone know of a good brand to buy a 12 Gauge?

I don't know a whole lot about guns in general, especially when it comes to specs, quality and brands. I do know a 12 gauge is the more typical option for security purposes and home defense, so that's where I'm starting. I'm just a little apprehensive to go buy a random shotgun because I'm looking for something reliable. Hopefully, y'all can give me some pointers. Thank you!
