Fusion in the context of Cyber Threat Intelligence (CTI) is frequently misunderstood. It is often perceived as the mere aggregation of disparate intelligence sources or the management of various random intelligence inputs. However, true fusion is a disciplined and strategic process that starts well before any data collection begins. It is the deliberate act of identifying a specific threat or theme that you want to understand in greater depth and then methodically managing and deploying your collection assets to gather relevant intelligence.
