Digital Evidence That Holds Up in a Dispute, Not Just on a Screen

A company discovers that an employee has transferred confidential documents to a competitor. Another suspects a supplier has falsified certifications for years. A third realises, too late, that the partner about to join the business already had an undisclosed commercial dispute in another country. In all three cases, the first signs surface online: emails, metadata, digital traces, public profiles. The challenge is not finding them. It is making them usable.

When a digital discovery is not enough

Faced with a suspicion, most companies do what anyone would: a Google search, a screenshot, a check on social media. This level of verification can confirm a hunch, but it rarely survives a legal challenge or a formal dispute. A screenshot without a documented chain of custody can be contested. Metadata read without the right tools can be deemed unreliable. A social media profile deleted in the meantime becomes evidence no one can verify anymore.

The distinction that matters is between information and evidence. Information guides an internal decision. Evidence must be presentable to a judge, an auditor, a board of directors, and withstand the question: "How did you reach this conclusion, and who can confirm it?"

Where companies lose evidentiary value

Three recurring blind spots, based on our experience:

Timing. Digital traces are volatile: content gets removed, profiles get edited, servers change. Every day of delay between the suspicion and the collection reduces what remains available.

Undocumented method. Knowing what was found is not enough. You also need to know how it was found, when, and with which tools — otherwise the evidence is worth no more than an unverified claim.

Confusion between similar digital identities. Names, companies and online profiles can overlap due to coincidence or homonymy. An investigation conducted without rigorous cross-checking risks building a case on the wrong identity — an error that invalidates the entire effort, even when the initial instinct was correct.

How we build a digital investigation that holds up

Our approach combines open source intelligence (OSINT) with digital forensics methodology, so that every piece of evidence collected can be traced back to its source and acquisition date. In practice, this means:

Certified acquisition, not improvised screenshots: every piece of digital data is collected using tools that preserve its integrity and verifiability over time. Cross-checked identity verification, to rule out homonyms or false matches before drawing any conclusion. Documented chain of custody, from first access to final report delivery, so the evidentiary trail can be reconstructed by an independent third party — legal counsel, an auditor, an authority. Connection to cybersecurity analysis, when an investigation reveals technical vulnerabilities, unauthorised access or data exposure, giving the client a complete risk picture rather than just an isolated event.

We work consistently alongside our clients' in-house or external legal teams: digital evidence only holds value if it is built, from day one, with its eventual use already in mind.

What to do before acting

When facing a well-founded suspicion — a leak, an anomaly, an inconsistency surfacing during due diligence — three steps help preserve what could otherwise be lost:

Do not intervene directly on the systems or profiles in question. Any undocumented access risks altering the traces or being challenged as tampering. Establish an internal timeline of events immediately, even informally: who noticed what, and when. This will help reconstruct the sequence with whoever conducts the investigation. Bring in specialist expertise before acting, not after. Evidence collected correctly from the start avoids having to explain, later, why it is no longer available or no longer reliable.

A digital discovery can shape an internal decision within minutes. Turning it into evidence that holds up in a dispute requires method, time and traceability — three things that rarely align with the urgency of the moment the suspicion first arises.
