Fostr uses multiple layers of technology to safeguard proprietary and sensitive video content. Core to this strategy is the implementation of Digital Rights Management (DRM), supplemented by in-player watermarking to protect against unauthorized recording or redistribution.
This document outlines the technical realities of DRM enforcement, known platform-level limitations, and the additional measures Fostr employs to enhance security.
Digital Rights Management (DRM) is a content protection standard that encrypts video streams and allows playback only under approved system and browser conditions. When effective, DRM restricts screen recording, copying, and retransmission of video content.
Fostr supports industry-standard DRM protocols:
These protections are embedded into the Fostr video player for all DRM-enabled tenants.
DRM effectiveness varies based on the user’s device and browser. While certain environments block screen recording reliably, others offer partial or no enforcement due to missing system-level requirements or policy limitations.
Platforms or browsers not listed below are either not widely adopted in production use cases or are not formally supported due to a lack of consistent DRM behavior. As such, their enforcement capabilities have not been validated and may vary.
| Operating System | Platform / Browser | DRM Used | Screen Capture Protection |
|---|---|---|---|
| MacOS & iOS | Safari | FairPlay | Fully enforced |
| MacOS & iOS | Widevine | Partially enforced | |
| Windows | Widevine | Partially enforced | |
| MacOS & iOS | Firefox | Widevine | Partially enforced |
| Windows | Firefox | Widevine | Partially enforced |
| Android | Android Browsers | Widevine | Partially enforced |
| All | Linux Browsers | Widevine | Not enforced |
