NSI Global is an Australian-owned intelligence, counterintelligence, and risk advisory firm founded in 2004 by Navid Sobbi. Our work helps clients establish facts, examine suspected compromise and assess risks affecting their information, people and operations.
In 2022 NSI Global acquired the Geopolitical Intelligence Group (GIG), a geopolitical risk advisory firm founded by Navid Sobbi in Canberra in 2018, which continues to operate as its geopolitical intelligence subsidiary.
Our clients trust us with their most sensitive challenges. Confidentiality is the cornerstone of every relationship we hold, and as a matter of principle we do not identify our clients.
Navid Sobbi continues to lead NSI Global as Chief Executive Officer and remains personally active across the firm’s core practices, including counterintelligence, technical surveillance countermeasures (TSCM), digital forensics, geopolitical risk and intelligence advisory. Within NSI Global’s Digital Forensics practice, he also serves as lead examiner.
He holds a Bachelor of Laws, a Master of Intelligence and a Master of International Security and Counterterrorism, majoring in Digital Forensics. He also holds a Diploma of Security Risk Management, Government Fraud Control and Investigative Services. He remains personally involved in complex digital forensic examinations, expert reporting and court-related matters.
Navid has prepared expert forensic reports and given expert evidence in numerous matters before Australian state and federal courts. These include matters before District and Supreme Courts, the former Federal Circuit Court of Australia and Family Court of Australia, their successor the Federal Circuit and Family Court of Australia, the NSW Court of Appeal and the NSW Court of Criminal Appeal.
His forensic work has principally been undertaken on instructions from law firms, law enforcement agencies, state Offices of the Director of Public Prosecutions and the Office of the Commonwealth Director of Public Prosecutions. He has also accepted direct instructions from individual and corporate clients in appropriate matters. His reports document the evidence examined, methodology applied, limitations encountered, findings reached and basis for any opinions expressed, allowing the work to be independently scrutinised and, where required, tested under cross-examination.
Published decisions referring to his work include Peek v Wheatley [2025] NSWSC 554 and the subsequent appeal, Wheatley v Peek [2025] NSWCA 265. In that matter, Navid acted as a joint court-appointed digital forensic expert to examine an Apple iPhone, prepared an initial and supplementary report, and was cross-examined. Both judgments recorded that there was no dispute concerning his evidence.
His professional affiliations include:
Navid also co-authored the chapter “Cyber Crime Applications” in Applications in Intelligence-Led Policing: Where Theory Meets Reality (2018; ISBN 9781720476542). The book examines the practical application of intelligence-led policing across Australia, Europe and North America and the role of intelligence analysis in preventative policing.
The wider NSI Global team includes practitioners drawn from intelligence, law, cybersecurity, engineering and specialist technical disciplines. Team members hold postgraduate and specialist qualifications across intelligence, law, digital forensics, cybersecurity and security risk management. Each engagement is assigned to practitioners with operational experience and technical expertise relevant to the matter.
We define the purpose and scope of the engagement, assign practitioners with relevant experience and explain the basis and limitations of our findings. Work is delivered in-house, with the agreed reporting and communication arrangements set out at engagement.
Accreditations and sector affiliations relevant to government and defence engagements are provided to vetted clients under NDA.
