What is the difference between counterintelligence and counterespionage?

Counterintelligence is the intelligence discipline, which attempts to protect our intelligence from falling into enemy hands. It seeks to detect, identify, and neutralize enemy intelligence threats. There are several ways the enemy attempts to gain our intelligence. The most well-known is through espionage (spying), but also includes intercepting communications, satellite imagery, open sources, etc. Counterespionage is counterintelligence activities, which specifically targets spies.
