They can restrict where content loads from, prevent MIME type guessing, reduce referrer leakage, and enforce encrypted transport.</p> <p>They are useful defense in depth, not a replacement for input validation, output encoding, authentication controls, or secure session handling. A strong header policy can limit the impact of some mistakes, but it cannot make an unsafe application secure by itself.</p>
