About NSI Global
Trusted Advisors
For more than two decades, NSI Global has managed complex, sensitive assignments for organisations that cannot afford to be compromised. We deliver the clarity our clients need to remain secure, compliant and resilient in an era of escalating physical, digital and geopolitical risk.
Our specialists provide counterintelligence and technical surveillance countermeasures, digital forensics and incident response, geopolitical and travel intelligence, offensive cyber security, enhanced due diligence and litigation support. We work across the government, defence, law enforcement, legal and corporate sectors, protecting our clients from financial loss, reputational damage and the compromise of their people, premises and information.
Our Commitment
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.
Our practitioners work continuously to stay ahead of illicit technology and tradecraft, investing in both our people and our technical capability. As threats evolve, so do our countermeasures — ensuring our clients always have access to current intelligence, forecasting and remediation.
For more than two decades, NSI Global has protected, served and informed the futures of the organisations we work with. It is why we remain one of the most trusted risk and intelligence advisory firms operating across Australia and the UAE.
Founder & Leadership
NSI was founded in 2004 by Navid Sobbi, who continues to lead the firm as Chief Executive Officer. Navid holds a Bachelor of Laws, a Master of Intelligence, and a Master of International Security and Counterterrorism, and remains personally active as a forensic practitioner and lead examiner.
Our wider team is drawn from intelligence, legal, cyber security, engineering and technical disciplines, and holds postgraduate qualifications across intelligence, law, cyber security and security risk management. Every engagement is delivered by practitioners chosen for their operational experience and specialist expertise.

Every NSI Global professional is bound by a strict code of ethical, confidential and legal conduct, and we hold ourselves to the standards expected by the government, defence and corporate clients we serve.
