Digital Forensics Consulting

Digital forensics is the identification, preservation, examination and reporting of electronic evidence found on computers, mobile phones, servers, email accounts, cloud services and social media.

Nokta Guard examines digital evidence on forensic images, without altering the original, and presents findings in a report that non-technical readers can follow. The legal weight of the report is for the relevant court or authority to decide.

Examination

Digital forensics consulting is the preservation and examination of digital traces and the reconstruction of events on the basis of evidence. Each examination is planned around its scope, the nature of the incident and the legal process.

Highlights

Every examination is carried out with chain of custody preserved and hash verification.

Process

Initial assessment and scope

We listen to what happened, agree the questions the examination must answer and list the devices, accounts and people in scope.

Authorisation and confidentiality

The legal basis for each device (court order, company policy or owner consent) is confirmed in writing, and the work is covered by an NDA.

Evidence intake and chain of custody

Devices are received with a handover record, and who held the evidence, when and why is logged throughout.

Forensic imaging

A bit-for-bit copy of storage media is taken, using a write blocker where technically possible.

Hash verification

Hash values (e.g. SHA-256) of the source and the image are calculated, compared and recorded.

Analysis on a copy

Analysis runs on a working copy of the verified image; the original evidence is kept untouched.

Reporting

Methods, tools, hash values and findings are presented in an objective report that non-technical readers can follow.

Return and retention

Original evidence is returned with a handover record; working files are either not retained at all or kept for 3 or 6 months, as the client prefers, and then securely destroyed.

Why does digital evidence need a specialist?

The value of digital evidence depends on how it was obtained. Simply switching on a device, copying a file or logging in to an account can change timestamps and call the reliability of the evidence into question.

That is why an examination must follow forensic practice from the very first step. A wrong move can permanently damage the integrity of the evidence.

Our service areas

Our digital forensics services fall into four groups:

Device examinations: computers and laptops, mobile phones and tablets, USB drives and memory cards, external drives and storage devices, servers and enterprise systems.
Communications, records and trace analysis: email, social media, internet and user activity, deleted data, file and document metadata, video and audio recordings.
Evidence, reporting and expert opinion: evidence integrity assessment, digital forensics reports, expert opinion and technical consulting.
Data recovery: mobile devices (including chip-off), hard drives and SSDs, encrypted drives, USB drives and memory cards.

03 / 05

How we work

Every engagement starts by identifying the digital material relevant to the case. Without altering it, we create a bit-for-bit copy, the forensic image, through a write blocker. All analysis is carried out on that image; the original is left untouched.

Our approach is aligned with the principles set out in ISO/IEC 27037, the international guideline for identifying, collecting, acquiring and preserving digital evidence.

04 / 05

How do we protect the chain of custody?

We record every step from the moment we receive the material until the report is delivered: what was received, from whom and when, which procedures were applied and where it was stored. This record underpins the reliability of the report.

05 / 05

Our confidentiality commitment

A non-disclosure agreement is signed before work begins. Material is kept in a physically secured, access-restricted environment, returned to its owner when the work is complete, and working copies are either not retained at all or kept for 3 or 6 months, as the client prefers, and then securely destroyed.

FAQ

Frequently Asked Questions

How long does a digital forensic examination take?

It depends on the type of material, the volume of data and the scope of the examination. We share an estimated timeframe after the initial assessment.

Can your report be used in court?

Our reports are prepared using forensic methods and the chain of custody is documented. Whether and how a report is used in legal proceedings, and how much weight it carries, is at the discretion of the court or relevant authority.

Will the examination damage my device?

In standard examinations the contents of the device are not altered; we work on an image acquired with write protection. Advanced techniques that may permanently damage a device, such as chip-off, are applied only with your written consent.

Can deleted data always be recovered?

No, we never promise a guaranteed result. Recoverability depends on the device, the file system, how much time has passed and whether the data has been overwritten. We give you a realistic assessment after a preliminary review.

Can you review a forensic report submitted by the other party?

Yes. We technically assess an existing digital forensics report in terms of method and findings and, if requested, prepare an expert opinion.
