Digital forensics is the technical process of collecting, preserving, analyzing, and reporting digital evidence from computers, mobile devices, and online systems. The goal is to keep evidence intact and explain findings clearly for legal use.

Technical questions about Digital Forensics, Evidence Preservation, and Criminal Investigation
We preserve chain of custody through a certified, documented process from collection to court. Every access is logged, forensic copies are validated, and storage is controlled so the evidence remains unchanged and traceable.
A technical assistant supports one party and helps legal teams understand the technical facts of the case. An expert witness is appointed by the court and must provide an independent technical opinion based on the evidence.
The process usually has four steps: acquisition, preservation, analysis, and reporting. We first create a forensic copy, then verify integrity, analyze relevant artifacts, and produce a clear report that documents methods and findings.
It depends on the number of devices, data volume, and technical complexity. A simpler case may take days, while larger or encrypted cases can take several weeks. We define scope and expected timelines at the start and keep clients updated during the process.
Our team maintains current Cellebrite certifications and follows ISO 27001-aligned information security practices. This technical training is combined with over 23 years of criminal investigation and forensic analysis experience.
Often yes, but recovery depends on time, storage type, and whether data was overwritten. We assess each device and extract what is technically recoverable, including deleted messages, files, and metadata when available.
Digital forensics in Portugal follows the Criminal Procedure Code and applicable data protection rules. Our work is based on certified chain-of-custody procedures, procedural confidentiality protected by law, and procedural cost framing under Portaria no. 10/2008, dated 03 January.
