The Cybersecurity and Infrastructure Security Agency’s (CISA) Enhanced Cybersecurity Services (ECS) program is an intrusion detection, prevention, and analysis capability that is available to all U.S. -based entities. ECS partners with accredited service providers who build and maintain classified systems capable of protecting ECS customer networks against malicious activity. CISA shares indicators of compromise through ECS where the systems detect and/or block potential malicious activity on an organization’s network. The ECS program embeds privacy protections into all of its operations.”]
