The responsibility of the Central Industrial Security Force (CISF) extends beyond protecting just the physical assets of an industrial establishment. Their mandate includes ensuring the overall security and safety of the premises, which inherently involves the protection of the employees working within those establishments.
CISF’s protective scope covers both assets and personnel within guarded establishments.
CISF’s role has diversified significantly and includes responsibilities for airports, metro systems, government buildings, museums, etc., demonstrating that their duties are not limited solely to industrial establishments or physical infrastructure protection. They can also be assigned duties outside India in specific contexts (e.g., embassy security, although this is not their primary role).
