DFIR

Digital Forensics and Incident Response

Definition

Digital Forensics and Incident Response combines the disciplines of investigating cyberattacks to determine what happened (forensics) and containing and remediating the threat (incident response).

Buyer context

DFIR teams collect and analyze digital evidence from compromised systems, reconstruct attack timelines, identify the scope of a breach, and support legal proceedings or regulatory reporting. Many SOC providers offer DFIR as an add-on or retainer service for when incidents escalate beyond routine alert triage.
