<p>BoundaryGuard Headers enforces modern HTTP security headers to harden your WordPress site against XSS, clickjacking, mixed content, and cross-origin attacks.</p>
<p><strong>Key Features:</strong></p>
<ul>
<li><strong>Essential Protection:</strong> Adds X-Frame-Options, X-Content-Type-Options, Referrer-Policy, and Permissions-Policy to reduce attack surface and prevent clickjacking.</li>
<li><strong>HSTS (Strict Transport Security):</strong> Forces HTTPS connections to help prevent protocol downgrade and man-in-the-middle attacks.</li>
<li><strong>Advanced Isolation (COOP/COEP):</strong> Enables Cross-Origin-Opener-Policy and Cross-Origin-Embedder-Policy to improve cross-origin isolation and mitigate certain side-channel attacks.</li>
<li><strong>Content Security Policy (CSP):</strong> 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><strong>CSP Report-Only Mode:</strong> Test your policy safely without blocking content.</li>
<li><strong>Server Header Hardening:</strong> Removes or limits exposure of headers such as <code>X-Powered-By</code> and <code>Server</code>.</li>
<li><strong>Lightweight and Fast:</strong> Uses PHP headers for broad server compatibility and minimal performance impact.</li>
<li><strong>No <code>.htaccess</code> Editing Required:</strong> Works without modifying server configuration files.</li>
</ul>
<p>Designed for developers and site owners who want stronger security without unnecessary complexity.</p>
<h3>External Services</h3>
<p>This plugin provides a Content Security Policy (CSP) builder. To assist users, it includes “Preset Buttons” that allow users to quickly add domain names to their own CSP whitelist.</p>
<p><strong>This plugin DOES NOT connect to, load data from, or send data to these services automatically.</strong> The following third-party domains are referenced as presets within the admin dashboard for whitelisting purposes:<br />

<p>SeaSP Community Edition is an automated <strong>Content Security Policy Manager</strong>. SeaSP allows you to create, configure, manage, and deploy a Content Security Policy for your site.</p>
<p>The WordPress SeaSP Community Edition plugin catalogs the domains that appear on your site. Categorize and filter out unwanted domains. Add a layer of WordPress security site from Magecart and other cross-site scripting attacks to keep your WordPress site safe.</p>
<p>SeaSP installs a strict non-blocking CSP to collect violation data and provide a violation report. Violation data flows into the WordPress database as a PHP option within the plugin options schema. Violations can be approved by domains and categorized by directives (CSS, fonts, images, JS, etc.). You can also approve base domains and subdomains. The SeaSP UI helps users by explaining what each directive does, and how to use them to create a CSP.</p>
<p>After configuring the domain and directive settings switch the CSP to blocking mode. Once the CSP goes into blocking mode, the site’s protected from any unrecognized code. SeaSP Community Edition helps secure your site.</p>
<h3>Upgrade Notice for 1.4 only</h3>
<ul>
<li>When you install this version you will need to rebuild your CSP</li>
</ul>
<h3>Usage</h3>
<p>Once installed, a strict non-blocking report-only CSP is implemented on your site. Visit each page of your site to collect CSP violations.<br />
Visit the Current Violations page of the plugin to review domains that have violated a directive in the CSP.<br />
Review each of the domains carefully and check for misspellings of common domains like adobee.com instead of adobe.com as this is a common way hackers inject content into your site.<br />
If you feel confident that the domain belongs on your site and it should be serving the file type stated, click the toggle to approve the domain to include it in the CSP.<br />
If you want to allow subdomains of that domain to be able to serve that type of content, click the Manage subdomains button to view the subdomains.<br />
After this process, you might still see CSP violations regarding inline scripts, inline styles, blobs, or data.<br />
To allow these this type of content in the community version you must navigate to the Directive Settings page, find the offending directive, then toggle the appropriate option.<br />
For convenience, each option has a tooltip explaining what it allows in your CSP.</p>
