Computer Forensics & DFIR

From cyberattack to courtroom: we respond to the incident, acquire the evidence with chain of custody and defend it before the court.

Computer forensics turns a cyberattack into evidence defensible before the courts. We combine judicial expert analysis with DFIR (Digital Forensics & Incident Response): we respond to the incident, acquire digital evidence with chain of custody (UNE 71505/71506) and turn it into an expert report we ratify in court. In Madrid and across Spain.

[ WHAT IS DFIR ]

Digital Forensics & Incident Response

DFIR is the discipline that combines two worlds judicial expert work needs: digital forensics, acquiring, preserving and analyzing evidence without altering it, and incident response, detecting, containing and eradicating the ongoing attack.

When we act fast and methodically, the same work that stops the cyberattack produces the technical evidence that sustains your case before the courts. The expert and the response team work together from minute one.
