The Central Industrial Security Force has replaced its largely geography-based supervision with sector-specific commands from November 1, with Home Ministry approval, to build specialised protection for strategic installations.

BulletsIn

• The Ministry of Home Affairs approved a functional reorganisation of the CISF that took effect on November 1, 2026.
• The earlier system managed most field formations by geographical boundaries, so one office could oversee installations from different industries.
• Under the new model, installations in the same sector come under one command, irrespective of where they are located.
• Sectors covered include power, coal, steel, petroleum and natural gas, government buildings, museums, monuments and mass rapid transit systems such as the Delhi Metro.
• Eight of the force's 11 existing supervisory sectors have been realigned, while three specialised sectors continue as before.
• The North Sector in New Delhi becomes the Power-I Sector and the North Eastern Sector-II in Kolkata becomes the Power-II Sector.
• The Western Sector in Mumbai is redesignated the West Coast Port Sector, and the Southern Sector in Chennai becomes the East Coast Port Sector.
• The two port sectors will oversee security at India's nearly 250 major and minor seaports.
• The Centre designated the CISF as the nodal seaport security force last year after it received recognition as a Recognised Security Organisation.
• CISF currently secures 13 major ports, including Jawaharlal Nehru Port in Maharashtra and Mundra Port in Gujarat.
• Airports, space facilities and atomic energy installations already operate under separate sector-specific CISF commands, and the new setup extends this approach.
• The force, set up in 1969 and headquartered in Delhi, has about 2.70 lakh personnel, and officials expect better oversight, uniform practices and closer coordination with ministries.
