BoundaryGuard Headers enforces modern HTTP security headers to harden your WordPress site against XSS, clickjacking, mixed content, and cross-origin attacks.
Key Features:
<ul>
<li>Essential Protection: Adds X-Frame-Options, X-Content-Type-Options, Referrer-Policy, and Permissions-Policy to reduce attack surface and prevent clickjacking.</li>
<li>HSTS (Strict Transport Security): Forces HTTPS connections to help prevent protocol downgrade and man-in-the-middle attacks.</li>
<li>Advanced Isolation (COOP/COEP): Enables Cross-Origin-Opener-Policy and Cross-Origin-Embedder-Policy to improve cross-origin isolation and mitigate certain side-channel attacks.</li>
<li>Content Security Policy (CSP): One of the strongest defenses against XSS. Includes a dashboard-based CSP builder with preset options to whitelist trusted sources for scripts, styles, images, and more.</li>
<li>CSP Report-Only Mode: Test your policy safely without blocking content.</li>
<li>Server Header Hardening: Removes or limits exposure of headers such as <code>X-Powered-By</code> and <code>Server</code>.</li>
<li>Lightweight and Fast: Uses PHP headers for broad server compatibility and minimal performance impact.</li>
<li>No <code>.htaccess</code> Editing Required: Works without modifying server configuration files.</li>
</ul>
Designed for developers and site owners who want stronger security without unnecessary complexity.
