Incident Response

Incident Response

A rapid and coordinated response to a cyber incident can determine whether an organization minimizes the impact on operations, data, and reputation. Incidents such as ransomware attacks, system breaches, data leaks, or compromised email accounts require expert intervention, forensic analysis, and crisis management.
