Digital Forensics & Incident Response
When a security incident occurs, every minute matters. Mishandled evidence, delayed containment, and unstructured response amplify both the technical damage and the regulatory exposure. 3R Infotech's Digital Forensics and Incident Response (DFIR) practice provides rapid, structured, expert-led support — from the moment you suspect a breach to the delivery of a court-admissible forensic report.
Our DFIR team brings deep technical capability and regulatory expertise, including chain-of-custody evidence handling, CERT-In compliant reporting, and experience across RBI-regulated breach notification requirements. We also provide proactive IR planning services so your organisation is ready before an incident ever strikes.
Digital Forensics
Forensic investigation requires precision, legal defensibility, and absolute chain-of-custody discipline. Our investigators are trained in forensic acquisition, analysis, and reporting standards that hold up to regulatory scrutiny and legal proceedings.
Forensic Investigation Capabilities
Endpoint & Device Forensics
- Forensic imaging of workstations, servers, and mobile devices

- Deleted file and artifact recovery
- Registry, prefetch, and event log analysis
- Browser and application artifact investigation
- USB and removable media forensics
- Anti-forensic technique detection
Network & Cloud Forensics
- Network traffic capture and protocol analysis
- Log correlation across SIEM, firewall, and proxy
- Email header analysis and phishing investigation
- Cloud environment forensics (AWS, Azure, GCP)

Incident Response
Our incident response methodology follows the NIST SP 800-61 framework, adapted for the Indian regulatory environment. We offer both reactive engagement (breach in progress) and retainer-based services that guarantee response times.
Incident Response Phases
-
Preparation — IR planning, playbook development, tabletop exercises, and retainer agreement
-
Identification & Triage — Rapid scoping of incident scope, initial containment actions, stakeholder notification
-
Containment — Isolating affected systems, preventing spread, preserving evidence integrity
-
Eradication — Removing threat actor presence, malware, and persistence mechanisms across the environment
-
Recovery — System restoration, configuration hardening, monitoring enhancement, and return to operations
-
Post-Incident Review — Root cause analysis, lessons learned report, and control improvement roadmap
