I like to imagine that Atlas has automatic turrets set up near entrances in the outer wall, so any average Grimm that come within those turrets' range ends up gunned down before it can manage to make it to the wall. If the turrets can move their aim fast enough, it would be enough to keep away the arctic fox Grimm I came up with. They're native to snowy places like the continent that Atlas is on. They're fast and tend to travel in packs, opting to annoy and tire out their prey.
