SOC (Security Operations Center)
A Security Operations Center is a team (and facility) responsible for continuously monitoring, detecting, investigating, and responding to cybersecurity incidents. SOC analysts rely on threat intelligence, SIEM platforms, and playbooks to triage alerts efficiently.
A SOC is the team that watches. It receives the alerts every security control produces, decides which ones are real, and hands the real ones to responders or handles them itself. It runs in shifts because attackers do not keep office hours, and it is measured on how fast it notices and how rarely it misses.
The daily problem is volume. A mid-sized environment produces thousands of alerts a day, most of them benign, and every one names indicators: a source address, a destination domain, a file hash. The analyst’s first move on almost every alert is to find out whether those indicators are known.
Threat intelligence is therefore not a report the SOC reads but a lookup it makes hundreds of times a day, usually from inside the SIEM or the case tool. The quality that matters is the answer’s speed and its honesty about confidence: a wrong “clean” closes a real incident, a wrong “malicious” burns an hour.
Example
An alert fires on an outbound connection to an unfamiliar domain. The enrichment returns “registered 2 days ago, resolves to a listed C2 address, confidence high” in under a second, and the alert is escalated with the evidence attached instead of sitting in a queue for triage.
In isMalicious
isMalicious feeds SOC tooling through the API and the SIEM and OpenCTI integrations described at /solutions/soc, so a lookup runs inside the alert rather than in a browser tab, and the report page is there for the analyst who wants the full evidence.
Frequently Asked Questions
What is SOC (Security Operations Center)?
A Security Operations Center is a team (and facility) responsible for continuously monitoring, detecting, investigating, and responding to cybersecurity incidents. SOC analysts rely on threat intelligence, SIEM platforms, and playbooks to triage alerts efficiently.
How is SOC (Security Operations Center) related to SIEM (Security Information and Event Management)?
SOC (Security Operations Center) and SIEM (Security Information and Event Management) are both key concepts in threat intelligence. A SIEM aggregates, normalizes, and correlates log data from across an organization's infrastructure to detect threats and support incident response. Popular SIEMs include Splunk, Microsoft Sentinel, and Elastic Security. Threat intelligence enrichment significantly improves SIEM detection accuracy.

Threat Intelligence
Threat intelligence is evidence-based knowledge about cyber threats, including observed infrastructure, behaviors, campaigns, and likely intent. It combines source observations with context so security teams can make a specific detection, triage, containment, or response decision.
Incident Response
Incident response (IR) is the structured process of detecting, containing, eradicating, and recovering from a security incident, then conducting a post-incident review to prevent recurrence. The SANS PICERL model defines six phases: Preparation, Identification, Containment, Eradication, Recovery, and Lessons Learned.
