To design and develop an indigenous, secure, and ruggedized Customer Premises Equipment (CPE) system to enable encrypted and reliable internet connectivity onboard Indian naval ships under the Secure Internet for onboard Naval Ships (SIFON) framework in coordination with TSP. With increasing digitalization of naval operations, secure internet access at sea has become a mission-critical requirement. SIFON aims to provide encrypted and authenticated internet services to Indian warships while maintaining operational secrecy and cybersecurity. Current solutions rely on commercial or imported hardware, which may pose security risks and are not tailored for naval environments. An indigenous CPE designed to meet naval requirements is vital for secure maritime connectivity.
