<p>Content Sentinel is a powerful WordPress plugin that enables secure, time-limited access to files stored in AWS S3 or S3-compatible storage providers (like Wasabi, DigitalOcean Spaces, and Backblaze B2). Perfect for protecting premium content, course materials, digital products, and media files.</p>
<h4>Key Features</h4>
<ul>
<li><strong>Secure File Delivery</strong>: Generate presigned URLs that expire automatically, ensuring your files remain protected</li>
<li><strong>S3 Browser</strong>: Browse your S3 bucket directly from WordPress admin (Pro feature)</li>
<li><strong>S3 Compatible</strong>: Works with AWS S3, Wasabi, DigitalOcean Spaces, Backblaze B2, and other S3-compatible providers</li>
<li><strong>Clean URLs</strong>: Use shortcodes to generate clean, user-friendly download links instead of long presigned URLs</li>
<li><strong>No AWS SDK Required</strong>: Pure PHP implementation – no external dependencies</li>
<li><strong>Easy Setup</strong>: One-click AWS CloudFormation setup or manual configuration</li>
<li><strong>Flexible Delivery Modes</strong>: Force download or stream/play in browser (Pro feature)</li>
<li><strong>Custom Denial Messages</strong>: Customize access denied messages (Pro feature)</li>
</ul>
<h4>How It Works</h4>
<ol>
<li><strong>Configure Your Storage</strong>: Connect to your AWS S3 bucket or S3-compatible provider</li>
<li><strong>Generate Secure Links</strong>: Use the shortcode <code>[content_sentinel_url key="/path/to/file.mp4"]</code> to create secure download links</li>
<li><strong>Automatic Expiration</strong>: Links expire after a set time (default: 10 minutes, configurable)</li>
<li><strong>Protect Your Content</strong>: Files are never directly accessible – users must go through WordPress authentication</li>
</ol>
<h4>Use Cases</h4>
<ul>
<li><strong>Course Platforms</strong>: Deliver course videos and materials securely</li>
<li><strong>Digital Products</strong>: Protect downloadable products and resources</li>
<li><strong>Membership Sites</strong>: Control access to premium content</li>
