Have you suffered a cyberattack? A data breach? Or perhaps you suspect a data leak or internal abuse? In these cases, you need a structured forensic investigation, not just a technical figure.

When it comes to computer forensics, you need a certified methodology, chain of custody, recognized tools, concrete experience, and above all, speed of action.

ISGroup does not offer hourly consultants. It offers complete, end-to-end forensic projects: from incident containment to the collection and analysis of digital evidence, up to legal support and regulatory compliance.

When a forensic investigation is needed

Typical scenarios

A professional forensic analysis is essential in situations such as:

• Data breach or suspected corporate data theft
• Suspicious employee behavior (off-hours access, log deletion, anomalous use of tools)
• Ransomware attacks with ransom demands or infrastructure compromise
• HR and legal investigations related to policy violations or internal disputes
• Compliance audits requested by Data Protection Authorities, DPOs, or certification bodies

Why a structured project beats an hourly consultant

Hiring an internal forensic analyst or relying on an hourly consultant may seem fast, but it is often ineffective:

Hourly consultant	ISGroup project
Single, often generic skill set	Multidisciplinary team: legal, technical, regulatory
Risk of wasting time or losing evidence	Guaranteed timeliness and formalized forensic processes
Dependence on standard commercial tools	Advanced and customized tools, even in unconventional environments
Poorly structured reports	Complete documentation, valid even in judicial contexts
No regulatory coverage	Guaranteed compliance with privacy and security regulations

With ISGroup, forensic analysis is not an isolated technical activity, but part of an incident management project that leads to a clear outcome: what happened, how, by whom, and what to do next.

How the forensic project works

Phase 1: Initial assessment

• Receipt of request and preliminary information gathering
• Needs analysis: ongoing incident, suspicion, audit, internal investigation
• Definition of objectives, timelines, and scope: technical, regulatory, legal
• Formalization of chain of custody, NDA, and data processing/retention processes

Phase 2: Customized execution

• Forensic acquisition of digital evidence (disk image, memory dump, logs)
• In-depth analysis (timeline, access, exfiltration, persistence, artifacts)
• Drafting of technical and legal reports, with evidence, hashes, and time references
• Debrief with stakeholders, support for remediation or escalation
• If requested: support for legal proceedings, with court-appointed or party-appointed experts

Phase 3: Measurable results

• Complete clarity on the event, impact, and responsibilities
• Documentation usable for compliance and legal actions
• Vulnerability identification and support for the improvement plan
• Delivery of forensic assets (copies, logs, signed reports) in a compliant manner

Frequently asked questions

• What is digital forensics and why is it really needed?
• Digital forensics is the set of techniques used to acquire, preserve, and analyze digital data for investigative purposes. It is essential for responding to cyber incidents, uncovering breaches, and proving what happened. It serves both technical and legal purposes.
• How quickly can a project be started?
• We can activate within 24 hours. Urgency is crucial in forensics: the more time passes, the more evidence can be altered or lost.
• Is it needed even if the IT team has already identified the incident?
• Yes. The IT team can detect anomalies, but only a certified forensic analyst can acquire and analyze data in a forensic manner, preserving legal and investigative value. Furthermore, it provides an impartial view.
• Can ISGroup operate in cloud environments or on mobile devices?
• Absolutely. We specialize in cloud-native forensics, containers, hybrid environments, as well as mobile devices and BYOD. We adapt tools and methodologies for every scenario.
• Is it possible to have reports valid for legal purposes?
• Yes. Every activity is documented according to legal best practices, with hashes, timestamps, chain of custody, and structured reports. Our analysts can also act as expert witnesses.
