LearnDash & LifterLMS Support
Your LMS handles the student enrollment, quizzes, and progression. Media Guard handles the file protection. Restrict lesson files directly to enrolled student roles.
Disable Downloads & Printing
PDFs render in a hardened, in-browser viewer. We strip out the download and print buttons, disable right-click, and intercept Ctrl+S saves.

Built for online schools and creators
Whether you're selling a single premium masterclass or running a massive membership academy, Media Guard keeps your intellectual property secure.
Course Creators
Stop students from pooling their money, buying one license, and sharing all your PDFs and lesson videos. Serve files via authenticated streaming so that only the logged-in student can access the material.
Membership Academies
Gate access to massive resource libraries using MemberPress, Restrict Content Pro, or Paid Memberships Pro. Assign files to membership tiers and surface them with the library shortcode.
Language Tutors & Coaches
Share practice tests, audio pronunciation guides, and vocabulary PDFs securely. Track exactly which students have opened which study materials using the built-in access logs.
Works with the LMS stack you already use
Your LMS handles the course flow. Media Guard protects the files inside that flow.
Four layers between your course files and unauthorized access
Server-level file denial
Protected files live in a directory blocked by NGINX or .htaccess rules. No direct URL access — the file is never served as a standard download.
Authenticated streaming
Files stream through a PHP endpoint that checks the student's enrollment role or WooCommerce purchase history before serving a single byte.
Hardened in-browser viewer
PDFs render in a stripped-down PDF.js viewer. Video and audio play through secure HTML5 players. Print, download, and right-click are intercepted.
Watermarks & access logs
CSS and dynamic watermarks overlay the viewer with the student's email. Every file view is logged — who viewed what, when, and from where.
