What This Service Covers
4n6PI provides on-demand incident response and forensic investigation services built for organizations that need rapid activation, structured response, and legally defensible outputs. The retainer model ensures you have experienced DFIR capability available when a security event occurs without waiting weeks to find and qualify a vendor mid-incident.
Engagements align with NIST SP 800-61 and industry-standard incident handling practices. All evidence collection follows documented chain-of-custody procedures suitable for internal, regulatory, or legal proceedings.
Core Capabilities
Incident Triage and Scoping
Rapid initial triage to confirm the nature of an incident, establish scope, and prioritize containment actions. Response initiation within defined SLA, typically within 4 hours of activation.
Forensic Evidence Acquisition
Forensically sound acquisition from endpoints, servers, cloud environments, and network sources. Chain-of-custody documentation maintained throughout. Supports Microsoft 365, Azure, and on-premises environments.
Attack Vector and Timeline Analysis
Log analysis, artifact correlation, and timeline reconstruction to identify how an incident occurred, what systems were affected, and when the activity took place.
Stakeholder Communication
Structured communication to executive leadership, legal counsel, and compliance teams, translating technical findings into clear business impact language throughout the engagement.
Containment and Remediation Guidance
Risk-based containment and remediation recommendations including secure restoration guidance and post-incident hardening strategies to reduce recurrence risk.
Litigation and Regulatory Support
Documentation and reporting structured to support legal proceedings, regulatory disclosure requirements, and law enforcement referrals when required.
Deliverables
Detailed documentation of root cause, scope, impacted systems, and reconstructed timeline, suitable for internal, legal, and regulatory use.
Chain-of-custody aligned records, collection methodology notes, and supporting artifacts for all acquired evidence.
Prioritized, actionable steps to close the attack vector, remove persistence, and reduce risk of recurrence.
Clear, concise summary of findings and business impact written for leadership and legal stakeholders, not just technical audiences.
