Shin Bet, also known as the Israel Security Agency (ISA), is Israel's internal security service. Its primary responsibility is safeguarding Israel's security by preventing terrorism, foiling espionage, and protecting vital infrastructure. Unlike the Mossad, which operates primarily abroad, Shin Bet focuses on internal threats, working closely with the Israel Defense Forces (IDF) and the Israel Police. The agency's methods often involve intelligence gathering, surveillance, and interrogation, sometimes generating controversy due to the sensitive nature of its work in maintaining national security.
