Chain of custody for digital evidence: a practical guide
Why Safrix

Purpose-built for investigations, not repurposed from e-discovery.

Teams evaluating Safrix often ask how it compares to Relativity, Nuix, Exterro or Case IQ. The honest answer is that most of them solve a different, heavier problem. Safrix is a focused, defensible place to run a sensitive investigation, from intake to report.

Two different categories

Relativity, Nuix and Exterro are e-discovery and digital-forensics platforms, built to ingest and analyse very large volumes of data for litigation and forensic casework. They are powerful, specialist and priced for that scale.

Case IQ and Safrix are investigation case management: the workflow around a case, not the mass processing of data. If your job is to run a defined sensitive matter and keep it defensible, you want the case layer, not a forensic engine.

Where each fits

Relativity

The dominant e-discovery and document-review platform for large-scale litigation, handling cases of millions of records with AI-assisted review.

Best when: You are reviewing very large document sets for a lawsuit.

With Safrix: For a contained internal investigation, that is more platform, cost and specialist skill than the job needs. Safrix runs the case and keeps the evidence defensible without an e-discovery engine, and can hold exhibits exported from a review tool.

Nuix

A forensic data-processing and link-analysis engine for investigators and digital-forensic specialists working with large or complex datasets.

Best when: You are processing devices or large datasets forensically, at scale.

With Safrix: Safrix is the case record around that work, not a replacement for the forensic engine. Feed its findings into Safrix as defensible, hashed evidence with a full chain of custody.

Exterro

A broad enterprise suite combining e-discovery, digital forensics and data-governance and privacy in one platform.

Best when: You need an enterprise data-risk platform across the whole data lifecycle.

With Safrix: If you specifically need investigation case management, Safrix does that one thing simply, rather than adopting a large multi-module platform for a single function.

Case IQ

Mature, widely used investigation case management for HR, ethics, fraud and misconduct. The closest comparison, and US-based.

Best when: You want a broad workplace-incident platform covering many case types.

With Safrix: Safrix differs by focus and depth, not breadth: cryptographic chain of custody and a tamper-evident audit as first-class, an insider-risk angle, and Australian data residency with cloud or on-premise deployment.

The difference

What makes Safrix different.

Defensibility as a primitive

Chain of custody and a tamper-evident audit trail are built into the core, not a bolt-on activity log. Every finding can be traced and verified.

Insider risk in the case

Explainable behavioural risk signals are surfaced inside the investigation, so teams prioritise with the reasoning on record.

Australian sovereignty

Data residency in Australia, with cloud or on-premise deployment, for regulated and government teams. A genuine gap for US-hosted platforms.

Right-sized and focused

Opinionated around sensitive investigations rather than a general everything-platform, so it is fast to stand up and simple to run.

When Safrix is the right tool, and when it is not

A good fit

Teams running sensitive internal investigations (integrity, insider risk, fraud, misconduct) who want a defensible, sovereign, focused system of record from intake to report.

Not the right tool

Large-scale litigation document review or device-level digital forensics. Pair Safrix with a specialist e-discovery or forensic tool, and keep Safrix as the defensible case record around it.
