Advanced Electronic Discovery

Standard electronic discovery finds and produces what is still there. NSI Global applies the Digital Forensic Incident Response Electronic Discovery Model (DFIR-EDM), a nine-stage method that adds forensic recovery of deleted and obscured material to that process — so that what was removed is recoverable, not simply absent.

• Stage 1 — Technical Planning. We establish what data exists, where it lives and what it is held on, before anything is touched. Scope errors at this stage are the most expensive to correct later.
• Stage 2 — Project Definition. Scope, legal obligations, timelines and deliverables are agreed with counsel, so the work is matched to what the matter actually requires.
• Stage 3 — Collections. Data is captured from devices, accounts and systems using forensically sound methods, with chain of custody maintained from the moment of capture. Planning and collection move together: what is found in collection often refines the scope.

From here the matter runs on two parallel tracks.

• Stage 4 — eDiscovery. Collected material is processed, de-duplicated, indexed and made searchable.
• Stage 5 — Hosted Review. The processed set is made available in a secure review platform, so legal teams can assess relevance and privilege directly.
• Stage 6 — Digital Forensics. In parallel, we forensically examine the collected material for deleted, hidden, altered and obscured data — what a standard discovery process would never surface. This is the stage that distinguishes DFIR-EDM.
• Stage 7 — Expert Services. Findings are documented as expert reports and affidavits, setting out the material examined, the method applied, the limitations and what can and cannot be concluded. Our examiners can give evidence on them.
• Stage 8 — Trial. We support the matter through hearing, including expert testimony where required.
• Stage 9 — Data Destruction. On conclusion, data is destroyed to an agreed standard and the destruction is certified, so holdings do not outlive the matter that justified them.
