India Introduces New Telecom Cybersecurity Rules for 2025

  • India’s amended TCS Rules introduce Telecom Identifier User Entities (TIUEs), covering banks, fintechs, e-commerce platforms, and messaging apps that use mobile-based authentication.
  • Messaging apps must enforce six-hour auto-logouts on web/desktop and adopt continuous SIM-based authentication to curb fraud.
  • OTT platforms such as WhatsApp, Telegram, Signal, and others now fall under mandatory data-sharing and cybersecurity compliance.
  • The reforms aim to strengthen cybercrime traceability, secure digital transactions, and increase accountability across telecom-linked services.
