Insurance has progressively emerged as one of the most significant instruments of social security in India. The situation has gradually developed insurances as one of the most influential social security tools in India. This paper focuses on discussing the complex role of insurance as a social security tool, the constitutional basis, the history, the theoretical background, the regulatory framework, and the experience of having government-sponsored programs. I consider the interface between welfare state theory and insurance-based social protection, evaluate the statutory and judicial environment on the sector, and critically review such flagship schemes as Pradhan Mantri Jeevan Jyoti Bima Yojana, Pradhan Mantri Suraksha Bima Yojana, Ayushman Bharat-Pradhan Mantri Jan Arogya Yojana and Atal Pension Yojana. The paper finds major gaps in awareness and access and equity in the regions and closes with policy suggestions in fortifying insurance based social security in India
