In this post, we’ll explore a Cyber Threat Intelligence (CTI) Maturity Model, designed to help organizations systematically enhance their threat intelligence capabilities. We’ll break down five maturity levels—ranging from initial, ad hoc practices to fully optimized and AI-driven CTI—and examine each level’s People, Process, and Tools requirements. We’ll also discuss transition milestones, standards alignment, real-world examples, and how to scale for different industries and business sizes.
