Incident response
Ransomware & Data Breach Analysis
Preserve the record while the response moves: initial access, persistence, lateral movement, affected systems, potential data access and the limits of what can be known.
The engagement
Analyze evidence while operations recover
Containment and forensic analysis happen on the same clock. A response that restores systems but destroys volatile evidence can make later notification, insurance, regulatory and litigation decisions harder.
GDF integrates evidence preservation with operational response. The examination follows the intrusion across identity, endpoints, network, cloud and affected business systems, producing an evidence-based timeline and a decision record for counsel and leadership.
Scope
Rapid forensic triage
Prioritize volatile and short-retention evidence while containment and restoration decisions are underway.
Endpoint and server analysis
Examine execution, persistence, credential access, lateral movement and payload artifacts.
Identity and cloud examination
Review authentication, administrative, mailbox and cloud audit records across the incident window.
Network and security telemetry
Correlate firewall, EDR, DNS, proxy, VPN and other available telemetry with host findings.
Data-access assessment
Test claims of access or exfiltration against logs, staging artifacts, transfer records and known gaps.
Counsel and insurer reporting
Technical chronology, scope statements, limitations and briefings designed for parallel decision tracks.
Methodology
How incident response works
-
Stabilize
Preserve the evidence most likely to disappear while supporting safe containment priorities.
-
Scope
Follow identities, hosts, network paths and cloud events to bound the incident.
-
Test
Corroborate actor claims and internal assumptions against the available technical record.
-
Document
Maintain a dated chronology, findings, limitations and remediation evidence for later scrutiny.

Frequently asked
Common questions
Should we rebuild affected systems immediately?
Business needs may require restoration, but preserve relevant volatile data, images and logs first where feasible. The sequence should be agreed by response leadership.
Can you prove that data was not taken?
Usually no examiner can prove a universal negative. We identify evidence of access or transfer, the sources reviewed, their coverage and the blind spots that limit the conclusion.
Do you work with breach counsel and cyber insurers?
Yes. We provide independent technical facts; counsel and the insurer make legal and coverage decisions.
