NFIR Digital Forensic Investigation is a professional forensic investigation service offered by NFIR, a certified private investigation agency based in the Netherlands. The service covers a range of digital forensic use cases including data breach investigations, hacking attack analysis, fraud investigation, extortion tracing, corporate information leak detection, OSINT research, and integrity/transgressive behavior investigations. Investigations are conducted on a variety of digital data carriers including computers, laptops, mobile phones, USB sticks, external hard drives, mailboxes, digital documents, and files. The forensic process follows four structured steps: securing digital traces, identifying evidence, creating forensic copies, and producing a final report. NFIR operates under strict legal and procedural standards, working only with internationally approved hardware and software. A legitimate interest assessment is conducted before any investigation begins to ensure compliance with privacy regulations. Findings are compiled into reports suitable for use in legal proceedings or submission to regulatory bodies such as the Data Protection Authority. NFIR holds ISO-27001, ISO-27002, and ISO-9001 certifications, audited by BSI. The company operates under POB permit 1672 and is supervised by the Dutch Department of Justice and Security. All investigators hold a yellow pass and are CERT certified. NFIR cooperates with tactical investigators, privacy lawyers, bailiffs, and agencies including the Police, NCSC, and the Public Prosecution Service.
