antiespionage
Against foreign spies
Antiespionage refers to efforts to detect, prevent, or counteract spying activities.
It describes measures taken by governments or organizations to protect secrets from foreign intelligence services or corporate competitors: antiespionage legislation, antiespionage units within the FBI.
The term overlaps with counterintelligence but emphasizes defensive rather than offensive operations.
