A Central Armed Police Force under the Ministry of Home Affairs, raised under the CISF Act, 1968, to provide security to industrial undertakings, critical infrastructure, and other vital installations.
The CISF is one of the five forces a candidate may join; its 1968 Act, its airport and metro security role, and its unique private-consultancy mandate are standard institutional facts.
The CISF guards installations and infrastructure; it is not a border-guarding force (that is the BSF, ITBP, SSB) and not a primary internal-security or anti-Naxal force (that is the CRPF), though it does provide some VIP security.
CAPF that guards airports, metros, and vital installations (CISF Act, 1968); only force allowed to give private security consultancy.
