Rapid Incident Response and Digital Forensics
During a Live Cyber Incident

Engagement Overview

This use case demonstrates how CyberXpert helped a UK regulated organisation contain a live cyber security incident, establish forensic clarity, and provide defensible assurance to senior leadership under significant operational and regulatory pressure.

Context

A UK-based organisation operating within a regulated sector identified indicators of a cyber security incident affecting critical systems and sensitive information. Given the nature of the environment, there was immediate concern around operational disruption, regulatory exposure, and potential data compromise.

Senior stakeholders required rapid assurance, clear evidence, and structured decision support aligned with UK regulatory expectations.

Challenge

Early indicators suggested possible unauthorised access, however internal capability was limited in determining the scope, root cause, and potential impact of the incident.

There was uncertainty around whether attacker access persisted, whether sensitive data had been accessed or exfiltrated, and how to respond in a controlled and defensible manner under significant time pressure. Delayed or incorrect decisions risked operational disruption, regulatory scrutiny, and loss of stakeholder confidence.

Approach

CyberXpert was engaged to provide immediate incident response and forensic support.

Immediate Containment and Stabilisation
Initial triage focused on rapid containment actions to stabilise affected systems and prevent further escalation while maintaining evidential integrity.

Forensic Investigation and Analysis
Structured digital forensic analysis was conducted to reconstruct an accurate timeline of events, determine the method of compromise, assess the scope of impact, and confirm whether any data exposure or exfiltration had occurred.

Stakeholder Assurance and Decision Support
Clear, evidence-based communication was maintained throughout the engagement to support legal, regulatory, and executive decision-making. Findings were presented in a structured and defensible format suitable for senior leadership review.

Following resolution of the incident, the organisation entered into an Incident Response Retainer to ensure rapid access to specialist support and strengthen future response readiness.
