When to Call NSI Global First
A device holds evidence you may need.
Before anyone resets, repairs or "cleans" a phone or computer involved in a dispute, fraud or allegation. The first actions decide what can be proven later.
Digital Forensics and Digital Evidence Services
Something said in private has become known.
A leaked board discussion, a competitor acting on internal strategy.
Technical Surveillance Counter Measures
A matter is heading to court and the digital evidence will be tested.
Reports that set out method, limitations and the basis for each opinion survive cross-examination. Ones that don't, don't.
Litigation Support
You suspect a device is being monitored.
Deleting the app or resetting the phone destroys the proof and warns whoever installed it.
Forensic Spyware and Malware Detection
You are about to sign with someone you don't fully know.
A counterparty, acquisition target, senior hire or distributor. What the data room leaves out is usually what matters.
Enhanced Due Diligence
Regional events are changing your risk.
Escalation, sanctions or instability in a market where you operate, assessed with sources and confidence stated.
Geopolitical Intelligence
