About

My name is Piotr Wichrań. I work at the intersection of technology, evidence, and liability.

I am a court-certified IT expert witness, licensed private investigator, and OT/IT cybersecurity specialist. I support matters where technology becomes part of a dispute, incident, investigation, or evidentiary process.

How I Work

My starting point is not technology itself, but a simple question:

what can be reliably established based on the available digital material?

In practice, this involves assessing:

• data integrity,
• acquisition methodology,
• chain of custody,
• forensic procedures,
• evidentiary limitations,
• logical validity of conclusions.

Experience

I have prepared more than 2000 expert reports and analyses in cases where methodology, evidentiary integrity, and accuracy of conclusions were critical.

My work combines three perspectives:

• court expert witness — methodology, evidentiary reliability, procedural value,
• private investigator — fact-finding, discretion, pre-litigation support,
• OT/IT and cybersecurity specialist — systems, incidents, architecture, and operational risk.

Areas of Practice

Digital Risk

Assessing situations where technology creates operational, legal, or reputational exposure.

Evidentiary Integrity

Supporting cases where preservation, integrity, and procedural value of digital material are essential.

Digital Forensics

Analysis of computers, mobile devices, storage media, logs, electronic documents, and user activity.

Incidents & IT Disputes

Supporting companies, executives, and legal teams in incidents, technical disputes, and conflict situations.

Professional Approach

I do not provide mass-market IT services.

I work in matters where the following are critical:

• discretion,
• methodology,
• precision,
• accountability,
• evidentiary value,
• communication understandable to executives and legal teams.

When It Makes Sense to Contact Me

It is worth reaching out if:

• a cybersecurity incident requires preservation of digital material,
• an expert report needs independent review,
• data, logs, devices, or electronic documents may become evidence,
• an IT dispute requires technical and procedural analysis,
• executives or legal teams need an independent digital risk expert.
