Comprehensive Coverage

5 Critical Headers Analyzed

We check the most important HTTP security headers that protect your WordPress site from common attacks.

X-Frame-Options

X-Content-Type-Options

Prevents MIME-type sniffing, ensuring browsers respect declared content types.

Recommended: strict-origin-when-cross-origin

Strict-Transport-Security

Forces browsers to use HTTPS for all future requests, preventing protocol downgrade attacks.

Recommended: max-age=31536000; includeSubDomains; preload

Why It Matters

Why Security Headers Matter

HTTP security headers are your first line of defense against common web attacks.

Clickjacking Protection

X-Frame-Options prevents attackers from embedding your site in hidden iframes to trick users into clicking malicious content.

XSS Mitigation

Content-Security-Policy controls which scripts can run on your pages, blocking malicious injection attacks.

HTTPS Enforcement

Strict-Transport-Security forces encrypted connections, preventing protocol downgrade and man-in-the-middle attacks.

Privacy Control

Referrer-Policy limits the information shared with third-party sites when users navigate away from your pages.
