Capability comparison

Security Incident Response (SIR) and Threat Intelligence

Security Incident Response manages the security-incident lifecycle. Threat Intelligence provides indicators, correlation, and threat context that make investigations faster and more informed.

Security Incident Response (SIR) provides

Structured security-incident intake, prioritization, and response workflows
Security tool and SIEM integrations that create prioritized security incidents
Workflow and automation to help analysts investigate, contain, eradicate, and recover from incidents
Coordination between SOC analysts, security managers, IT teams, and remediation owners
Asset and business-impact context for prioritizing response work

Threat Intelligence provides

Indicators of compromise and structured threat data for investigation enrichment
Configured threat lookups, searches, and correlation for incident-response teams
STIX and TAXII support for sharing and operationalizing threat intelligence
Structured intelligence used to enrich and relate security investigations
Targeted campaign and threat-actor analysis beyond an individual incident

Consider it when

The SOC already has a repeatable security-incident process but analysts still perform manual indicator and threat lookups.
Threat feeds, STIX or TAXII sources, or a threat-intelligence team need to drive investigation decisions instead of living outside the response workflow.
The organization needs consistent correlation, campaign analysis, or threat-actor context alongside incident response.
Do not treat Threat Intelligence as a prerequisite for standing up SIR - add it when the team has usable intelligence sources and a process to act on them.

Where the capabilities overlap

Both support Security Operations teams responding to threats, but SIR manages the incident-response workflow while Threat Intelligence supplies the threat context and correlations used during that work.
Both can use security-tool data, but SIR turns signals into prioritized response cases while Threat Intelligence curates and analyzes indicators, campaigns, and external intelligence.

Security Incident Response (SIR) and Threat Intelligence can be adopted independently. The sequence shown is practical implementation guidance, not an installation prerequisite.

What it is (plain English)

A structured workspace for the security team to handle security incidents - phishing, malware, breaches - with guided playbooks, automated enrichment, and integration to security tools (SIEM, EDR). It brings the discipline of IT incident management to the SOC, with the CMDB providing asset context.

Problems it solves

Security incidents handled in email and chat with no consistent process.
Analysts manually pivoting between disconnected security tools.
No metrics on response times or incident volume/trends.
Slow, inconsistent triage without playbooks.

What must exist first

Platform Core Setup and CMDB Foundation (asset context for affected systems). Integrations to security tooling (SIEM/EDR) via Integration Foundation drive most of the value.

What the customer needs to provide

Your security tool stack (SIEM, EDR, threat feeds) and how it will connect.
Your current incident response process and severity model.
Playbook content for common incident types.
SOC team structure and escalation paths.

Where it can go next

Threat Intelligence enriches investigations; Vulnerability Response (VR) closes the loop on exploited weaknesses; can create/relate IT Incident Management records; orchestration/automation accelerates containment.
