For over 20 years, NSI Global has provided digital forensic services, digital forensic incident response, cyber incident investigation, electronic evidence preservation and forensic analysis for corporate organisations, government agencies, law enforcement bodies, law firms, insurers, regulators and authorised case-managed matters.

Digital forensics is the specialist process of identifying, preserving, extracting, analysing and reporting on data from electronic devices, cloud accounts, communications platforms and digital systems in a forensically sound manner.

Our digital forensic practice is led by NSI Global’s founder, Navid Sobbi — who has given expert forensic evidence in Australian courts — and is delivered in-house by credentialed examiners. Meet our forensic lead

NSI Global’s digital forensic work is conducted by experienced specialists, including legally qualified and court-experienced forensic examiners who understand the technical, legal, evidentiary and security requirements involved in sensitive investigations. We have supported criminal prosecutions, internal corporate investigations, civil litigation, and family law matters.

Our team assists in matters involving cyber incidents, business email compromise, ransomware, insider threat, employee misconduct, intellectual property theft, unauthorised access, spyware, malware, deleted data recovery, mobile devices, cloud accounts, eDiscovery, litigation support and evidence preservation.

NSI Global provides digital forensic support where there is a lawful, authorised and appropriate instruction pathway. In domestic violence, family law, child safety, criminal, civil, AVO/protection order or other sensitive legal matters, NSI Global must deal directly with the lawyer, case officer, investigator, insurer, law enforcement body, government agency, recognised support organisation or authorised representative.

What Is The Unique NSI Digital Forensic Methodology?

Our Key Digital Forensic Services include:

Our digital forensics team holds advanced qualifications, including Master’s degrees in cyber security, digital forensics and information security. We image every device before examination and work only from the copy, using the forensic tools courts and law-enforcement agencies rely on — Cellebrite, Oxygen, MobilEdit, X-Ways, just to name a few — with documented hash values and a full chain of custody, so findings hold up for courts, regulators and insurers. We examine data from all device types, including smartphones, computers, tablets, smart watches and cloud accounts.

Frequently Asked Questions

Is digital forensic evidence admissible in Australian courts?

Yes, provided it is collected and preserved using a forensically sound methodology with a defensible chain of custody. This is the standard NSI Global's forensic process is built around.

What's the difference between digital forensics and standard data recovery?

Standard data recovery focuses on retrieving lost files. Digital forensics goes further — preserving evidence to a legally defensible standard, documenting the process, and producing findings suitable for court, regulatory, or investigative use.

How quickly should a forensic expert be engaged after a suspected breach?

As early as possible. Evidence on live systems and devices can be altered or lost through normal use, which is why early, forensically sound preservation is critical to protecting what's recoverable.

Can NSI Global assist with domestic or family law matters?

Yes, where the matter is engaged through a legal representative or case officer, ensuring the right protections are in place for all parties involved.

Does NSI Global work with law enforcement and government agencies?

Yes. NSI Global has provided digital forensic services to government departments, law enforcement, law firms, and corporate organisations across Australia for over 20 years.

What happens after a digital forensic examination?

You receive a comprehensive report detailing the findings, methodology, and chain of custody, prepared to a standard suitable for legal or litigation use where required.
