Espionage, spying, or intelligence gathering is the act of obtaining secret or confidential information (intelligence). A person who commits espionage is called an espionage agent or spy. Any individual or spy ring, in the service of a government, company, criminal organization, or independent operation, can commit espionage. The practice is clandestine, as it is by definition unwelcome. In some circumstances, it may be a legal tool of law enforcement and in others, it may be illegal and punishable by law.
