守る (mamoru) is the most general and can be used for physical, abstract, and emotional protection. 防ぐ (fusegu) focuses on preventing something bad from happening, like an attack or disaster. 保護する (hogo suru) is formal and often used in legal, social, or institutional contexts, such as protecting children, wildlife, or data.
