DHS Enhanced Cybersecurity Services (ECS)
Enhanced Cybersecurity Services (ECS) is an intrusion prevention and analysis capability that helps U.S.-based companies protect their computer systems against unauthorized access, exploitation, and data exfiltration. ECS works by sharing sensitive and classified cyber threat information with accredited Commercial Service Providers (CSPs). These CSPs in turn use that information to block certain types of malicious traffic from entering customer networks. All U.S.-based public and private entities are eligible to enroll in ECS. Program participation is voluntary and is designed to protect government intelligence, corporate information security, and the privacy of participants.
