As opposed to the British Security Service and US FBI, its jurisdiction is much more restricted, with state police agencies often taking the lead. External and offensive counter-intelligence, counter-terrorism, and some direct action is the general responsibility of Mossad, although military units will carry out specific counterterrorism actions.

Mossad, on foreign intelligence, also works with Aman, the military intelligence service. Shabak is the Israeli domestic counterintelligence organization.
