Post-Data Breach Investigations
Senior-Led Review Support Following Data Breaches & Cyber Incidents
A data breach does not end when the immediate incident is contained. Organisations must quickly understand what information has been compromised, identify affected individuals, assess regulatory obligations, and produce accurate, defensible evidence under significant time pressure.
DAS provides senior-led operational support for post-data breach investigations, combining experienced review professionals, defensible workflows, and technology-enabled review strategies to help organisations respond efficiently and confidently.
Supporting Organisations Through Complex Post-Breach Reviews
Modern data breaches often involve vast quantities of structured and unstructured information spread across multiple systems, custodians, jurisdictions, and languages.
Understanding exactly what information has been exposed requires more than simply searching files. It requires carefully designed workflows, experienced judgement, robust quality assurance, and operational governance that can withstand regulatory scrutiny.
While eDiscovery tools and investigation workflows provide valuable capabilities, post-breach review is not identical to traditional document review. DAS applies what is transferable, but our extensive experience across numerous post-breach matters has shown where specialised logic, additional workflow steps, and manual intervention are required. We design review processes that incorporate the strengths of existing technology while addressing the gaps that arise when identifying compromised information, affected individuals, and regulated data.
DAS supports organisations throughout the review process, helping legal, privacy, compliance, and cyber response teams understand the scope of compromised information while maintaining defensibility at every stage.
How DAS Supports Post-Breach Investigations
- Compromised Data Review: Review large volumes of potentially exposed documents, emails, databases, and electronic records.
- Identification of Affected Individuals: Identify individuals whose information may have been compromised.
- PII Review: Identify personal, confidential, privileged, commercially sensitive, and regulated information.
- Multilingual Data Review: Review compromised information across multiple languages and jurisdictions.
- Quality Assurance & Validation: Apply structured quality control processes.
- Regulatory Response Support: Support responses to regulators, legal advisors, and insurers.
- Risk-Based Categorisation: Classify compromised information by sensitivity and potential harm to support a proportionate regulatory response.
- Volume-Reduction Strategies: Apply targeted filtering, deduplication, and triage techniques to reduce dataset size before review.
Defensible Review Under Regulatory Pressure
DAS designs review workflows that prioritise governance, auditability, quality assurance, and operational documentation, enabling organisations to demonstrate a structured and proportionate response.
Technology Supports Accuracy, Not Assumptions
DAS remains technology‑agnostic, recommending tools based on operational suitability while ensuring experienced professionals oversee every review decision.
GenAI enhances identification, categorisation, summarisation, and riskindicator detection within the tools we already use.
Our approach recognises where technology accelerates accuracy and where post‑breach complexity requires human judgement, specialised workflows, and manual validation.
Where appropriate, DAS incorporates specialised post‑breach reporting capabilities that support the final identification of affected individuals and the preparation of structured, regulator‑ready outputs. These capabilities complement, rather than replace, defensible review workflows, ensuring validated findings, manual checks, and operational governance flow into a complete and reliable final report.
