Useful intelligence explains not only what has been observed, but why it matters to a particular organization, how confident the assessment is, and what action the recipient can take.
CTI may be strategic for leaders, operational for campaign and incident planning, tactical for understanding attacker behavior, or technical for identifying specific infrastructure and artifacts. A raw feed of addresses, domains, or file hashes is data; it becomes intelligence only after analysis and contextualization.
Sharing formats such as STIX and transports such as TAXII let communities exchange structured intelligence at machine speed, but the deciding factor is the intelligence requirement: what the organization needs to know, for which decision, and by when. A program that cannot name its requirements collects noise, not intelligence.
