Secure IPTV platforms use dynamic tokens, signed URLs, encrypted HLS segments, DRM systems (Widevine, FairPlay), user-agent locking, GEO/IP restriction, and watermarking. Tokens prevent link sharing by requiring every stream to be authenticated. DRM ensures that only authorized devices decrypt the video. Encrypted HLS protects content from restreaming bots. Providers recommended by Glanfy often combine DRM + token rotation + CDN-level security for maximum protection.
