What We Do
Quorum Cyber’s Digital Forensics and Incident Response (DFIR) team helps organisations respond to ransomware, cloud compromise, business email compromise, insider threats, and complex enterprise intrusions with the experience and operational expertise needed to regain control during complex cyber incidents.
Combining forensic investigation, threat intelligence, frontline SOC visibility, and deep Microsoft security expertise, our specialists rapidly identify malicious activity, determine what is at risk, and support effective containment and recovery.
Incident Response
Lead and coordinate the response to active cyber incidents, helping organizations contain threats quickly, reduce operational disruption, and stabilise critical business operations.
Digital Forensics
Investigate how attackers gained access, what activity took place, what systems, identities, or data were affected. We help organisations understand the scope and impact of the incident while preserving critical evidence.
Threat Containment & Recovery
Identify and contain ongoing malicious activity while supporting remediation, recovery, and restoration of business services. Our teams help organizations recover safely while reducing ongoing risk.
Ransomware Negotiation
Support organisations through ransomware extortion events with intelligence-led assessments, controlled communications, and strategic guidance informed by real-world attacker behavior and frontline SOC visibility.
Enhanced Monitoring (TMDR)
Enhance visibility across endpoints, identities, email, and cloud environments using Microsoft security telemetry and investigative tooling to support containment and response decisions in real time.

Our Response
Every incident is different, but our approach follows a structured, intelligence-led process designed to contain threats, reduce disruption, and support operational recovery.
Identify: establish visibility, assess the scope of the incident, and determine what systems, identities or data may be affected
Contain: take immediate action to stop ongoing attacker activity, limit spread, and stabilise critical business operations
Investigate: Conduct forensic analysis and threat hunting to understand how the incident happened, what actions were taken, and whether the threat is still in the environment
Recover: support remediation, recovery, and restoration of services while helping teams safely return to normal operations
Strengthen: help organisations address gaps exposed during the incident to improve resilience and reduce future risk
Throughout the engagement, we work closely with technical teams, executives, legal counsel, cyber insurers, and external stakeholders to support informed decision-making under pressure.
