Cyber Threat Intelligence

Cyber Threat Intelligence (CTI) is the practice of collecting, processing, and analyzing data to understand a threat actor's motives, targets, and attack behaviors. This evidence-based knowledge, which includes specific indicators of compromise (IoCs) and details on tactics, techniques, and procedures (TTPs), provides the necessary context for an organization to make informed decisions about its security. By transforming raw data about emerging or existing threats into actionable intelligence, CTI enables organizations to shift from a reactive to a proactive security posture, allowing them to anticipate, prevent, and more effectively respond to cyber attacks.
