10 Security Headers Every Website Must Have
A practical guide to the browser headers that reduce clickjacking, injection, data leakage, and downgrade risk.
Security headers are one of the fastest ways to reduce visible website risk without changing application logic.
Start With Browser Controls
Prioritize HSTS, Content Security Policy, X-Frame-Options or frame-ancestors, X-Content-Type-Options, and Referrer-Policy.
These headers help browsers make safer decisions before vulnerable code or third-party scripts can do damage.
Roll Out Carefully
Use report-only mode for Content Security Policy before enforcing it on production traffic.
Monitor blocked resources, then tighten the policy around the scripts and domains your site truly needs.
