Well, the first protection that comes to mind is that there are two
windshields at cruise: the droop snout has an outer windshield to
smooth high-speed aerodynamics. This presumably protects the real
windshield, which is only exposed when the nose is dropped for takeoff
and landing, and is presumably what holds the air in. The chances of a
foreign object penetrating both is probably vanishingly small.
