What is CTI?
CTI, or cyber threat intelligence, is intelligence about cyber threats. It is a process that starts from raw data, enriches it and analyzes it to produce contextualized, reliable information useful for decisions: who might attack us, how, and what should we do?
CTI follows a cycle: direction (defining needs), collection, processing, analysis, dissemination, then feedback. This cycle distinguishes CTI from a mere accumulation of feeds: it aims at action, not archiving.
Why it matters for your organization
CTI lets you move from a reactive posture to an anticipatory one. Rather than waiting for the incident, you understand the actors relevant to your sector, their modes of operation and their targets, which steers defensive priorities.
Well integrated, it feeds several functions: it supplies detection with indicators and techniques, informs vulnerability management about what is actually exploited, and gives leadership a view of risk grounded in real threat rather than assumptions.
The three levels of CTI
- Strategic: high-level trends and risks for decision-makers.
- Operational: campaigns, threat actors and their intentions.
- Tactical: indicators of compromise and techniques (TTPs) for detection.
Where organizations most often fall short
The most widespread mistake is confusing CTI with a subscription to feeds. Buying indicators without analyzing them or tying them to your needs produces noise, not intelligence. Useful CTI starts from specific decision questions and is judged by its ability to change an action, not by the volume of data ingested.
