Central Industrial Security Force (CISF)

The Central Industrial Security Force, or CISF, is an armed police force of the Union government that guards India's most important installations. It protects airports, seaports, power plants, steel plants, coal mines, oil refineries, atomic energy and space centres, the Delhi Metro, Parliament and many government buildings and monuments. It works under the Ministry of Home Affairs (MHA) and is one of India's Central Armed Police Forces (CAPFs). Think of it as a specialised, trained security guard service for the places the country cannot afford to lose.

Why does it exist?

After Independence, India built large public sector factories, steel plants, power stations and mines. These were expensive and vital to the economy, but local police or private guards could not protect them properly from theft, sabotage, fire or attack. The government wanted one trained, disciplined force that understands industrial security. So it created the CISF to guard these places full-time.

Where did it come from?

• 1968: Parliament passed the Central Industrial Security Force Act, 1968.
• 10 March 1969: The CISF was set up with about 2,800 personnel. 10 March is celebrated as CISF Raising Day.
• 1983: An amendment (Act 14 of 1983, in force from 15 June 1983) declared the CISF an armed force of the Union. This gave it the status of an armed force like the other CAPFs.
• 1999: An amendment added Section 14A, allowing the CISF to give paid security consultancy to private industry.
• 2000: The CISF took over security at its first airport, Jaipur, on 3 February 2000. Airport security soon became one of its biggest jobs.
• 2007: It took over security of the Delhi Metro from the Delhi Police.
• 2009: The CISF (Amendment) Act, 2009 allowed it to guard private sector and joint venture companies, on a cost-reimbursement basis (the company pays). The first private client was the Infosys campus in Bengaluru, from July 2009.
• 2024: From 20 May 2024, it took charge of security of the entire Parliament complex.
• 2025: The MHA approved raising its authorised strength from about 1.62 lakh to 2.2 lakh personnel. In November 2025 it was named the Recognised Security Organisation for seaports under the ISPS Code.

How does it work?

The CISF does not guard places on its own choice. A ministry, public sector company or approved private company asks for CISF cover. The MHA approves it, and the client pays the cost of the force deployed. A CISF unit is then posted at the installation. Units are grouped into larger sectors, each led by an Inspector General (IG), and the whole force is led by a Director General (DG), usually a senior IPS officer, from its headquarters in New Delhi.

A simple way to picture it: the client is like a housing society that hires a security agency, but here the agency is a trained armed force of the Union.

What does the CISF do?

• Industrial security: steel plants, coal mines, power stations, oil and gas units, fertiliser plants.
• Aviation security: passenger and baggage screening and perimeter security at civil airports.
• Port security: access control, cargo screening and seafront patrolling at major ports, and now a regulating role for about 250 seaports.
• Strategic sites: atomic energy and space establishments, under a dedicated DAE and DoS Sector.
• Urban and heritage security: Delhi Metro, government buildings, museums and monuments such as the Taj Mahal.
• Fire protection: it has a dedicated Fire Wing, among the largest firefighting services in the country.
• Consultancy and VIP security: paid security and fire consultancy to industry, and protection of certain persons through its Special Security Group.

The 2026 restructuring: territorial vs functional command

For most of its history, CISF supervised units by region. So one IG in Ranchi looked after coal mines, power plants and steel plants together, just because they were nearby. But each type of plant has different risks. A coal mine faces theft and fire; a refinery faces explosion and gas leaks; a port faces smuggling and threats from the sea.

Under the new functional (sector-based) model, all coal units report to a Coal Sector, all power units to Power sectors, and so on. Officers then build deep expertise in one domain and apply the same standards everywhere. CISF already used this model for airports and for atomic energy and space sites for about 25 years.

Commonly confused concepts

• CISF vs CRPF: CISF guards fixed installations (plants, airports, ports). The Central Reserve Police Force (CRPF) is the main force for internal security operations, riots and counter-insurgency.
• CISF vs private security guards: Private guards work under the Private Security Agencies (Regulation) Act, 2005 and have no special legal powers. CISF personnel are an armed force of the Union with powers given by the CISF Act, 1968.
• CISF vs NSG: The National Security Guard (NSG) is a special counter-terror commando force. It is not a CAPF and is not posted to guard installations day to day.
• CISF vs Railway Protection Force (RPF): The RPF guards railway property and passengers and works under the Ministry of Railways, not the MHA.
• CISF vs BCAS: The Bureau of Civil Aviation Security (BCAS) is the regulator that sets airport security rules. The CISF is the force that carries them out at many airports.

Issues, criticism and the way forward

• Growing workload: Airports, metros, ports and Parliament have added huge new duties, so recruitment must keep pace with demand.
• Cost for clients: Because clients pay for CISF cover, some smaller ports and companies hesitate to use it.
• Personnel welfare: Long duty hours, frequent transfers and postings far from family are long-standing concerns across CAPFs.
• Administrative impact of the new model: Sector-based command can mean longer travel for staff, because the IG for their sector may now sit in a distant city.
• New threats: Drones, cyber attacks on control systems and insider threats need new skills. CISF is building drone, anti-drone and cyber capabilities.
• Way forward: steady recruitment against the 2.2 lakh ceiling, sector-specific training, more technology at gates and perimeters, and strong coordination with installation managers and regulators.

Concepts to Know

• Armed force of the Union: A force created by a central law, armed and controlled by the Union government, as opposed to a state police force.
• Critical infrastructure: Facilities so important that their damage would seriously hurt the economy, public safety or national security, such as power grids, ports, refineries and nuclear plants.
• Cost-reimbursement basis: The client that gets CISF protection pays the government back for the salaries and costs of the personnel posted there.
• Inspector General (IG): A senior police rank; in CISF, an IG commands a sector made up of many units.
• ISPS Code: The International Ship and Port Facility Security Code, a set of global maritime security rules adopted under the International Maritime Organization after the 9/11 attacks and in force since 2004.
• Recognised Security Organisation (RSO): A body authorised under the ISPS Code to carry out security assessments and prepare security plans for port facilities.
