The 4 Essential Security Headers Every Website Needs

  1. Strict-Transport-Security (HSTS): Forces modern browsers to communicate solely over encrypted HTTPS, preventing SSL stripping attacks.
  2. Content-Security-Policy (CSP): Restricts the domains from which scripts, styles, and images can load, neutralizing 95% of Cross-Site Scripting (XSS) attacks.
  3. X-Frame-Options: Set to DENY or SAMEORIGIN to prevent attackers from embedding your website into transparent iframes (Clickjacking).
  4. X-Content-Type-Options: Set to nosniff to stop MIME-type sniffing vulnerabilities.

Audit your website's security posture on the Header Inspector Tool on Tools24Now.
