What is Threat Intelligence

Threat intelligence is the systematic examination of factual data on cyber threats, empowering security professionals to interpret incidents within their own environments and craft precise countermeasures for identified vulnerabilities.

Built on raw data—much like open source intelligence—this practice delivers critical insights (for example, who your adversaries are, what drives them and what resources they possess, and which signs of compromise to watch for), all of which inform smarter security decisions.

As industries accelerate their digital transformations, the need for strong cyber defenses continues to climb. Statista forecasts the global Cyber Threat Intelligence market will exceed $44 billion by 2033, underscoring the value of data-driven protection in corporate strategy. Likewise, the Recorded Future 2023 State of Threat Intelligence survey found that roughly 70.9 percent of organizations have dedicated teams focused on gathering and interpreting threat data.

In the following sections, you’ll gain a comprehensive look at how a mature threat intelligence program can uncover, assess, and neutralize cyber risks—ensuring a proactive security posture. You’ll learn about its fundamental elements, why it matters, and how to integrate it into your organization to prevent intrusions and attacks.
