Digital Forensic Services

Defensible Digital Forensic Investigations

CISO Global collects, preserves, and analyzes digital evidence to determine what occurred, which systems and data were affected, and what conclusions the evidence supports.

Investigators document how evidence is collected, preserved, handled, and analyzed from intake through reporting to help protect its integrity for legal, regulatory, insurance, and incident response matters.

When to Use Digital Forensics

Organizations use digital forensics to preserve and examine electronic evidence, establish an incident timeline, determine the scope of activity, and document findings for internal or external review.

A forensic investigation may be appropriate for:

Investigating a breach, ransomware event, business email compromise, or data-loss incident
Examining suspected insider activity, employee misconduct, or unauthorized access
Providing technical findings to legal counsel, law enforcement, regulators, insurers, or auditors
Determining which systems, accounts, or data were affected
Preserving relevant data before systems are rebuilt, restored, or materially changed

Digital Evidence We May Examine

The investigation scope, available data, legal authorization, and systems involved determine which evidence sources the team reviews.

Potential evidence sources include:

Endpoint, server, and file-system data
Security, audit, application, and system logs
Email and collaboration-platform data
Identity, authentication, and access records
Cloud, SaaS, and infrastructure logs
Network and firewall data
Storage devices and removable media

Evidence Integrity Controls

Evidence handling begins with a defined scope and documented authorization. Investigators preserve original evidence where applicable, document collection and transfer activity, and maintain records showing how the evidence was handled throughout the investigation.

Evidence integrity controls include:

Forensically sound data collection
Preservation of original evidence and working copies
Documented evidence handling and chain of custody
Clear reporting of findings, methods, and limitations

Scope and Preserve

Confirm the investigation objectives, authorization, systems, users, and data in scope
Identify and preserve relevant evidence
Document collection and evidence handling

Examine and Analyze

Review available evidence for signs of compromise or unauthorized activity
Correlate events across systems, accounts, and timelines
Identify relevant activity, affected assets, and investigative limitations

Document and Report

Develop a clear investigative timeline and narrative
Connect findings to the supporting evidence
Prepare technical and executive-level reporting for the approved stakeholders

An inventory of evidence collected and reviewed

Documented evidence-handling and chain-of-custody records

An incident or activity timeline

Findings linked to supporting evidence

Identification of affected systems, accounts, or data where the evidence allows

A report covering methods, findings, conclusions, and limitations

Incident response or remediation recommendations, when applicable

Digital Forensics and Incident Response

When an incident requires both forensic analysis and response support, CISO Global can coordinate the investigation with its broader Incident Response Services. Forensic findings can then guide containment, remediation, recovery, and post-incident reporting.

Documented Evidence Handling

Investigators document collection, preservation, transfer, and analysis activities throughout the engagement.

Integrated Incident Response

Forensic findings can directly inform containment, remediation, recovery, and post-incident reporting.

Reporting for Multiple Stakeholders

Reports connect conclusions to supporting evidence and explain the methods, findings, and limitations for technical and executive audiences.

Authorized External Coordination

At the client’s direction, investigators can coordinate technical information with legal counsel, insurers, law enforcement, regulators, and other approved parties.

Protect the Integrity of Digital Evidence

Work with digital forensics experts who understand chain of custody, evidence-handling requirements, and defensible investigative methods.

How do you help protect digital evidence integrity?

CISO Global uses documented collection, preservation, transfer, and analysis procedures to help protect evidence integrity. The final determination of admissibility is made by the applicable court or authority.

Do you support legal proceedings and expert testimony?

CISO Global may provide expert consultation or testimony when the engagement scope, investigator availability, jurisdiction, and applicable requirements allow.

How do you maintain chain of custody?

We document evidence collection, preservation, transfer, storage, and analysis to maintain a clear record of how evidence was handled throughout the investigation.

Do you work with law enforcement agencies?

At the client’s direction, our investigators can coordinate technical information and evidence submissions with law enforcement or federal agencies when required by the engagement.

Can forensic investigations support insurance claims?

Digital forensics can provide technical findings, incident timelines, evidence records, and impact documentation that insurers may use when evaluating a claim.
