Threat intelligence is the knowledge-based approach to understanding adversaries, their capabilities, and their intentions through the systematic collection, analysis, and dissemination of threat data. It transforms raw security data into actionable insights that enable organizations to anticipate attacks, prioritize defenses, and respond faster to incidents. Unlike reactive security measures that wait for alerts, threat intelligence builds a proactive posture by mapping the threat landscape to your specific environment. At its core, effective threat intelligence answers three questions: who is targeting you, how they operate, and what you should do about it—making it the bridge between data and decision-making that defines modern security operations.
