Digital forensics and incident response (DFIR) services help organizations identify the extent of, and deal with security incident investigations, forensic response and triage, and security breaches. They generally offer a combination of digital forensics (DF), incident response (IR) and related proactive and reactive security services. DFIR is mostly delivered as a retainer-based service, and is intended to work with the end user’s in-house DFIR processes and procedures.
