A computer forensics investigator is the individual responsible for the practice of identifying, extracting and considering evidence from digital media, such as computer hard drives. Digital evidence is both fragile and volatile and requires the attention of the investigator, which should be a qualified specialist, to ensure that materials of evidentiary value can be effectively isolated and extracted in a scientific manner that will bear the scrutiny of a court of law.

The vernacular of digital or computer forensics investigator is forensicator.
