What is Threat Intelligence?
Threat intelligence is analyzed, contextualized information about current and emerging cyber threats, including threat actor profiles, attack campaigns, malware families, and TTPs, that enables security teams to make informed, proactive defensive decisions.

How Threat Intelligence Works
Raw threat data (a list of malicious IPs, a malware sample) becomes intelligence when analyzed, contextualized, and made actionable. Intelligence has four tiers: strategic (high-level trends for executive decisions, such as "ransomware targeting healthcare increased 40% this year"), operational (specific planned or ongoing campaigns), tactical (TTPs used by specific actors), and technical (IOCs for detection systems).
Sources include commercial feeds (Recorded Future, CrowdStrike Intel), open-source (VirusTotal, MISP community feeds, AlienVault OTX), government (CISA advisories, FBI Flash alerts), and internal telemetry. Intelligence platforms (TIPs) aggregate and normalize these sources, letting analysts query actor profiles, relate indicators to campaigns, and understand confidence levels.
Intelligence-driven security shifts the SOC from purely reactive to proactive: hunting for techniques used by threat actors targeting your industry before those techniques trigger alerts.
Threat Intelligence in SOC Operations
You use threat intelligence continuously: enriching alerts with actor attribution, checking IOC reputation during investigation, and using threat actor TTPs to guide hunting hypotheses. An analyst investigating a suspicious process should query threat intelligence to see if involved IOCs are attributed to a known group. That context dramatically changes severity assessment and response priority.
