Every time you pass through security at an Indian airport, walk into a metro station in Delhi or Mumbai, or approach a government building in the capital, there is a good chance the uniformed personnel managing your security belong to the Central Industrial Security Force (CISF). Yet most people know very little about how this force is structured, what each rank means, or how officers rise through the ranks.
This guide breaks down the complete CISF rank hierarchy — from Constable to Director General — with pay scales, roles, and everything you need to know, whether you're an aspirant, a researcher, or simply curious.
What is the CISF? — The Central Industrial Security Force (CISF) is a Central Armed Police Force under India's Ministry of Home Affairs, established in 1969, responsible for security of critical infrastructure including airports, seaports, metro systems, nuclear installations, space facilities, heritage sites, and government buildings.
CISF: A Force Built Around Infrastructure Security
Unlike CRPF (internal security) or ITBP (border guarding), CISF has a unique mandate — protecting India's critical economic and strategic infrastructure. It is the only CAPF with a dedicated fire wing and a VIP security unit (Special Security Group). As of MHA Annual Report 2023-24, CISF's authorised strength is approximately 1,88,394 personnel, deployed across more than 353 industrial units and establishments, including all operational civilian airports in India.
CISF Rank Structure: The Two-Tier System
- Gazetted Officers (Group A & B): Assistant Commandant and above, recruited through UPSC CAPF (AC) examination or departmental promotion
- Non-Gazetted / Enrolled Personnel: Constables through Inspectors, forming the bulk of the operational strength
CISF Gazetted Officer Ranks: Full Hierarchy
| Rank | Pay Level (7th CPC) | Basic Pay (Rs.) | Army Equivalent |

What Each CISF Rank Actually Does
Constable (GD) — The Face of Airport Security
CISF Constables are the personnel you interact with most at checkpoints. They operate X-ray machines, conduct physical frisking, manage access control at entry gates, patrol perimeter fences, and enforce security protocols at industrial units. At airports, they implement Bureau of Civil Aviation Security (BCAS) mandated procedures under CISF command.
Head Constable — Section Supervisor
Manages a small group of Constables at a specific post or security station. Handles shift handover records, maintains post logs, and escalates security incidents to the ASI/SI.
ASI and Sub-Inspector — Shift In-Charge
The SI/ASI typically commands a platoon or security shift at a unit. At airports, the SI coordinates with airline ground staff, BCAS inspectors, and local police during security alerts or incidents. They prepare daily security reports and are first responders to breaches at the post level.
Inspector — Unit-Level Operations Manager
The Inspector manages security operations across an entire section of a large unit (e.g., one terminal of an airport). They handle duty rosters, training of lower ranks, coordination with the client organisation (AAI, NPCIL, etc.), and incident reporting to the Commandant.
Assistant Commandant — Entry Gazetted Officer
Recruited directly via the UPSC CAPF (AC) exam. Commands a company of approximately 100 personnel and is responsible for security planning, threat assessment, and liaison with the management of the protected installation. The AC is the junior-most officer who can independently represent CISF in meetings with client organisation heads.
Deputy Commandant — Unit Administration
Second-in-command of a CISF unit (a security deployment at one establishment). Manages HR, logistics, training schedules, and assists the Commandant in all administrative and operational functions.
Commandant — Unit Commander
The Commandant is the head of a CISF unit — the complete security deployment at a single establishment (e.g., an airport or a nuclear plant). This is a critical command role. The Commandant directly interfaces with the senior management of the client organisation (e.g., Airport Director, Plant Superintendent) and is responsible for the entire security posture of that installation.
Deputy Inspector General — Sector / Regional Commander
Oversees multiple CISF units within a sector or region. Coordinates policy implementation, conducts security audits of units, and maintains liaison with state governments and intelligence agencies in their jurisdiction.
Inspector General — Zonal Command
Commands a CISF Zone comprising multiple regions and dozens of units. The IG interfaces with MHA, BCAS, and other central agencies on security policy for the category of installations in their zone.
Director General — The Apex
The DG is the highest authority in CISF — responsible for all policy, operations, and administration across every deployment. The DG reports to the Ministry of Home Affairs and represents CISF at the highest inter-agency forums, including the National Security Council framework.
CISF's Unique Units: Beyond Standard Security
Fire Wing
CISF is the only CAPF with an integrated fire service. The Fire Wing provides fire protection at industrial units including refineries, chemical plants, and airports. Personnel in the Fire Wing hold equivalent CISF ranks (e.g., Leading Fireman = Head Constable equivalent) but are separately trained and deployed. CISF fire services operate under the Petroleum and Explosives Safety Organisation (PESO) norms.
Special Security Group (SSG)
CISF's VIP protection unit, the SSG provides personal security to central government ministers, senior officials, and other protectees assigned by MHA. SSG personnel undergo specialised close-protection training and hold standard CISF ranks.
Reserve Battalions
CISF maintains reserve battalions that can be deployed for additional security during special events, elections, or to supplement state police during communal situations — similar to other CAPFs.

Frequently Asked Questions
What is the highest rank in CISF?
The highest rank in the Central Industrial Security Force is the Director General (DG), an Apex Scale post at Level 17 of the 7th CPC pay matrix (fixed pay Rs. 2,25,000/month). The DG heads the entire force and reports to the Ministry of Home Affairs.
What is the salary of a CISF Constable?
A CISF Constable (GD) earns a basic pay of Rs. 21,700/month at Level 3 of the 7th CPC. Total emoluments are higher after adding Dearness Allowance, HRA, and unit-specific allowances. Personnel at airports or high-security installations may receive additional special duty allowances.
Is CISF only for airports?
No. While CISF is best known for airport security, it protects a much wider range of critical infrastructure — including nuclear power plants (under NPCIL), space research facilities (ISRO), seaports, metro rail systems, oil refineries, steel plants, heritage monuments (including the Taj Mahal), and central government buildings. Airports account for a significant portion of CISF's deployments but are not its only mandate.
What is the difference between CISF and CRPF?
CISF specialises in static security of industrial and critical infrastructure installations, while CRPF is India's primary internal security and counter-insurgency force deployed across conflict zones, for election duties, and in support of state police. Both are CAPFs under MHA and share the same rank structure and pay scales, but their deployment profiles and operational environments are very different.
Can CISF personnel be deployed for law and order duties?
Yes, though it is not their primary role. CISF reserve battalions can be deployed by the central government for election duties, law and order assistance, or special security events, similar to other CAPFs. However, their primary statutory mandate under the CISF Act, 1968 is the protection of specified industrial establishments and critical infrastructure.
What is the CISF Fire Wing?
The CISF Fire Wing is an integrated fire protection service within CISF, unique among CAPFs. It provides fire-fighting and fire prevention services at high-risk industrial units including petroleum refineries, chemical plants, and airports. Fire Wing personnel hold CISF ranks with separate designations (e.g., Leading Fireman, Station Fire Officer) and are trained under fire service norms.
How many airports does CISF guard?
As of 2024, CISF provides security cover to 67+ operational civilian airports across India, as mandated by the Bureau of Civil Aviation Security (BCAS) under the Ministry of Civil Aviation. This includes all major international airports such as Delhi, Mumbai, Bengaluru, Chennai, Hyderabad, and Kolkata.
