Digital Forensic and Incident Response

What is Digital Forensic and Incident Response (DFIR)

What is Digital Forensic and Incident Response (DFIR)

Digital Forensics and Incident Response (DFIR) helps organisations respond effectively to cyber threats such as ransomware attacks, data breaches, insider threats, business email compromise and advanced persistent threats (APTs). Security teams use DFIR to identify the source of an attack, assess its impact, preserve digital evidence and implement corrective actions to prevent similar incidents in the future.

Organisations use DFIR to minimise operational disruption, reduce financial and reputational risks and maintain regulatory compliance. DFIR analyses systems, networks, endpoints and digital artefacts to deliver actionable insights. These insights help organisations make informed decisions, strengthen their security posture and improve resilience against evolving cyber threats.
