INSEC has been ardently involved in protection and promotion of Human Rights for more than one and a half decade.  Founded by inexorable HR defender late Prakash Kaphley and prominent HR activist Sushil Pyakurel, INSEC significantly contributed in institutionalizing the democratic polity in the nation from a rights based approach, both at the policy and grassroots levels, especially after the restoration of democracy in 1990/91.

Ever since its establishment, INSEC has played momentous role in raising number of human rights issues to the national agenda and influencing the necessary policies and legislations. INSEC has constantly emphasized economic, social and cultural rights in its agenda right from its initial days when it implemented the program for the cart pushers of Kathmandu valley in 1989. It has been involved in highlighting issues of bonded labour, minimum wage for the agricultural workers and other issues concerned with human rights.

In course of time, INSEC has gradually identified its core competency areas from its own experience, feedbacks provided by the stakeholders and from internal and external performance evaluations. Its identified areas of strength have been organizing campaigns, awareness creation and education programs for making people capable of asserting their civil and political rights and documentation of human rights situation of the country and its dissemination at national and international arenas. Education, monitoring, lobbying, advocacy, research and training on issues related to human rights have been major regular undertakings for INSEC for more than a decade already.

As human rights NGO, INSEC is focused towards working with disadvantaged groups. Its targeted working groups have been the agricultural laborers, underprivileged women, and socially discriminated people including Dalits and children. INSEC Strategy (2003-2007) has been the major guideline for INSEC to launch its programs in the sector of human rights and social justice.
