About the DFIR & Threat Intelligence Practice:
The DFIR & Threat Intelligence Practice helps organizations prepare for, respond to, and recover from cyber incidents, turning front-line experience into intelligence that keeps clients ahead of the threat. Six specialized teams work as one across the full arc of an incident, from readiness planning through response, recovery, and threat research. We partner with client security and legal teams, cyber insurance carriers, breach counsel, and GuidePoint's regional and sales organizations to cut dwell time and limit business impact.
The six teams:

• DFIR (Digital Forensics & Incident Response) — Breach investigation, forensics, containment, and eradication when an incident is confirmed or suspected.
• IRA (Incident Response Advisory) — Readiness before an incident: IR planning, tabletop exercises, Blue Team enablement, and program maturity assessments.
• GRIT (GuidePoint Research and Intelligence Team) — Original threat research and intelligence that drives our investigations, Threat Actor communications, TI advisory, and as-a-Service capabilities.
• SD (Strategic Delivery) — Delivery management that keeps engagements staffed, on track, and consistent.
• R&R (Recovery & Restoration) — Post-incident rebuild that returns clients to safe, operational environments.
• Insurance & Counsel — The bridge to carriers and breach counsel through the claims and legal side of an incident.

What sets us apart: one integrated practice carries a client through the whole lifecycle with no hand-off gaps, including the demanding parts of an engagement that most providers cannot cover in-house, from GRIT's Threat Actor communications and negotiation support to R&R's full environment restoration and coordination with insurers and counsel. GRIT's research feeds live investigations so our response reflects how adversaries operate now, and established carrier and counsel relationships make GuidePoint a trusted partner across the incident response community.
