NSG And CISF: Understanding Two Pillars Of India’s Internal Security

India’s security architecture relies on forces with distinct responsibilities — from responding to terrorist attacks and rescuing hostages to protecting airports, industrial facilities and critical national infrastructure. In this week’s Classroom Edition of Defence Mantra, we examine two such forces under the Ministry of Home Affairs: the National Security Guard (NSG) and the Central Industrial Security Force (CISF).

Established on 16 October 1984, the NSG was created to tackle exceptional terrorist threats requiring specialised capabilities. Known as the Black Cats, its personnel undergo rigorous selection and training for counter-terror operations, hostage rescue, counter-hijack missions and bomb-related duties. Its operational history includes Operation Black Thunder in 1988, the response to the Akshardham Temple attack in 2002, and Operation Black Tornado during the 26/11 Mumbai attacks. The NSG’s regional hubs, established following the 2008 attacks, strengthened its ability to respond to crises across the country.

The CISF, raised on 10 March 1969, has evolved from its original industrial-security mandate into a force protecting a broad range of public and private-sector installations. Its responsibilities include civil airports, the Delhi Metro, nuclear and space facilities, power plants, ports, heritage monuments and Parliament. Its dedicated fire wing adds another dimension to its role in protecting critical assets.

Despite their different mandates, both forces face a changing threat environment. Drone incursions, cyber vulnerabilities, insider threats, manpower constraints and increasingly complex attack scenarios demand continuous adaptation.

This episode explores how the two forces are structured, how personnel are selected and trained, what their operational histories reveal, and where their biggest challenges lie.

The distinction is fundamental: the NSG is a specialised force of last resort for exceptional counter-terror contingencies, while the CISF provides security to critical installations as part of its continuing operational mandate. Together, they illustrate the different capabilities required to safeguard India’s people, assets and national interests.
