Plex is a privately owned company based in the United States. Founded in 2009, with approximately 180 employees, it functions as a tier 1 media tech buyer, known for its media and TV services. The company operates a comprehensive media platform that serves as a one-stop destination for entertainment, combining a free, ad-supported streaming service with a personal media organization tool. Its free service provides over 50,000 on-demand movies and shows, alongside more than 600 live TV channels. A core offering is the Plex Media Server, software enabling users to organize and stream their personal collections of movies, TV shows, music, and photos to any device. Additionally, Plex provides a universal watchlist for tracking titles across all streaming services, offers movie rentals, and features a premium 'Plex Pass' subscription that unlocks advanced personal media management capabilities, including a DVR and the dedicated 'Plexamp' music app.
Plex confirmed a defect in version 2026.18.0 of its Apple TV client on September 18, 2026. This version surfaces "Binge-Worthy Shows" programming even when users have explicitly disabled Plex’s online media sources, overriding the preference to keep ad-supported streaming content out of view on tvOS. The defect does not expose or alter a user’s personal Plex libraries. Previously, on September 9, 2026, a warning indicated that over 36,000 internet-exposed Plex Media Server installations remained unpatched against recently disclosed security issues. This situation occurred alongside reports of a ransomware operation disrupting the RelyComply AML platform in Great Britain, highlighting a growing cybersecurity crisis where attackers leverage existing vulnerabilities and poorly maintained internet-facing systems, potentially involving the BlueMoon exploit chain.
