Case studies

Practical outcomes for high-stakes data and security challenges.

Explore how Nightingale Data Solutions helps organisations recover what matters, respond with confidence, and build stronger digital operations.

Selected outcomes

Experience that translates into action

Every engagement is handled with care, clear communication, and a focus on decisions your team can act on. Our forensic analysis work covers digital evidence recovery, computer forensics, mobile and email investigations, insider threat reviews, ransomware response, and cyber security incident analysis.

Data Recovery

Restoring critical business records after a storage failure

A fast-growing organisation faced a failed storage system containing finance, operations, and customer records. Our recovery team stabilised the media, created forensic images, and rebuilt the accessible data without risking further damage.

The challenge

A degraded storage system with business-critical files, limited backup coverage, and a narrow recovery window.

Our approach

  • Preserved the original media and assessed failure conditions
  • Created verified working copies for safe recovery
  • Recovered priority folders and validated files with stakeholders

The outcome

Recovered the priority business dataset and returned the organisation to normal operations with a practical backup improvement plan.

Cyber Security

Containing an endpoint incident and strengthening the security baseline

After suspicious activity appeared across several employee devices, our cyber security team helped the organisation contain the incident, understand the attack path, and reduce the likelihood of a repeat event.

The challenge

Unusual endpoint behaviour, incomplete visibility, and uncertainty about whether sensitive systems had been accessed.

Our approach

  • Triaged affected endpoints and preserved relevant evidence
  • Mapped indicators of compromise and likely attack paths
  • Prioritised remediation, monitoring, and response improvements

The outcome

The organisation regained confidence in its environment and left with a clearer incident response process and measurable security priorities.

Digital Forensics

Reconstructing a timeline after suspected insider data theft

A professional services firm identified unusual transfers from a privileged user account shortly before an employee departure. The investigation needed to establish what happened while preserving evidence suitable for internal review and potential legal action.

The challenge

Conflicting user accounts, incomplete audit records, and a requirement to separate authorised business activity from unauthorised copying.

Our approach

  • Preserved laptops, removable media, and relevant cloud audit records
  • Examined file access, browser, USB, and authentication artefacts
  • Built a time-sequenced activity timeline and documented evidence handling

The outcome

The firm received a defensible chronology of events, a clear list of affected information, and focused recommendations for access and offboarding controls.

Mobile Forensics

Recovering evidence from a damaged mobile device

A damaged smartphone contained messages, location history, and media relevant to a sensitive workplace investigation. The device could not be reliably operated, and repeated attempts to access it risked changing valuable artefacts.

The challenge

Physical damage, limited device availability, and the need to protect personal data outside the agreed investigation scope.

Our approach

  • Documented the device condition and established an evidence-handling record
  • Used a controlled acquisition workflow appropriate to the device state
  • Filtered and reviewed relevant communications, locations, and media with investigators

The outcome

Relevant evidence was recovered and presented in an organised report while maintaining a clear audit trail and proportionate privacy controls.

Email Forensics

Tracing a business email compromise

An organisation discovered that supplier payment instructions had been altered during an active email compromise. We analysed the mailbox and message headers to distinguish genuine correspondence from attacker-controlled activity.

The challenge

Spoofed messages, forwarding rules, suspicious sign-ins, and uncertainty about which recipients had received manipulated instructions.

Our approach

  • Preserved relevant mailbox content and authentication logs
  • Analysed headers, routing information, rules, and sign-in history
  • Mapped the communication timeline and identified affected conversations

The outcome

The organisation understood the compromise path, corrected the affected processes, and strengthened mailbox monitoring and payment-verification controls.

Incident Response

Preserving evidence during a ransomware investigation

A mid-sized organisation experienced widespread file encryption across shared systems. The priority was to contain the incident without destroying evidence needed to understand the entry point, scope, and recovery options.

The challenge

Operational pressure to restore services quickly, multiple affected endpoints, and a risk that well-intended remediation could overwrite forensic artefacts.

Our approach

  • Advised on isolation and prioritised evidence preservation before recovery actions
  • Collected and examined endpoint, server, and security-control artefacts
  • Correlated indicators to identify affected systems and likely intrusion stages

The outcome

The response team gained a reliable incident picture, a prioritised containment plan, and evidence-informed recommendations for resilient recovery.

Forensic Audit

Validating disputed access to confidential records

An organisation needed an independent review after confidential records appeared to have been accessed outside normal working patterns. The engagement focused on facts, reproducibility, and a report that decision-makers could understand.

The challenge

Large audit datasets, inconsistent timestamps across systems, and a need to avoid assumptions before the evidence was reconciled.

Our approach

  • Collected access logs, identity records, endpoint artefacts, and relevant system exports
  • Normalised timestamps and compared activity across independent sources
  • Produced a structured findings report with limitations and confidence levels

The outcome

The organisation received a clear, evidence-led assessment that supported its internal decision-making and guided improvements to logging and least-privilege access.
