Defensible Data Handling Across the Breach Response Lifecycle

TCDI has supported hundreds of cyber incidents, ranging from business email compromise and ransomware to inadvertent disclosure and insider threat matters. From our London office, we combine AI-enabled data mining, specialist review and a Lean Six Sigma operating model to help you move from data processing through notification list creation with confidence and cost certainty.

From Data Processing to Notification List Creation

Every breach response engagement follows a clear path from data processing through notification list creation. Here is how we manage each stage, keeping you informed every step of the way.

The bulk of data exposed in a cyber incident doesn’t contain personal information, which is why disciplined data reduction is the single biggest way to control cost and timing. We leverage AI-enabled data mining workflows with human-in-the-loop verification to defensibly cull data before it reaches review.

Workflows are tailored to the matter at hand, weighing the following items:

  • Industry
  • Data types
  • Source systems
  • Custodian roles
  • Jurisdictional considerations
  • Insurance limits

Doing so allows us to design a culling strategy that surfaces what matters most while setting aside what doesn’t.

Once data reaches review, we leverage AI to identify PII within the context of each document. This minimises false positives and ensures reliable extraction outcomes.

Our review team then performs quality control, confirming individuals were correctly identified and PII has been discovered in full. We validate accuracy by manually reviewing samples and stratifications of PII entries, so the dataset arrives at notification with a defensible record behind it.

Our team handles the full range of data exposed in cyber incidents:

  • Personally Identifiable Information (PII)
  • Protected Health Information (PHI)
  • Personal Financial Information (PFI)
  • Payment Card Industry (PCI) Data
  • Confidential Business Information
  • Exposed Structured Data Sets

Where data must remain in country, we work with trusted in-country partners for review under the guidance of our London team. Where data can be transferred lawfully, the project is managed by our US-based review teams.

Once review is complete, we build consolidated, deduplicated notification lists for counsel’s review and action. AI-assisted matching and quality control checks confirm records are ready to support notification under UK GDPR, the DPA 2018 and ICO reporting obligations.

At the end of the engagement, you’ll receive:

  • Final Notification List
  • Support Analytics
  • Clear Audit Trail of How Decisions Were Reached

Control Costs without Compromising Defensibility

Breach response costs can spiral quickly when data volumes aren’t managed well. We have built our process around predictable pricing and disciplined data reduction, so the cost of a response stays proportionate to the matter.

» Defensible Culling First
We mine and reduce data before review, where the highest costs live, so you pay to review what matters.

» AI-Enabled Efficiency
Automated PII identification and AI-assisted notification list creation cut manual hours without cutting corners.

» Volume-Based, Transparent Pricing
Fixed-fee structures and defined pricing bands provide cost predictability.

» A Team that Scales with the Matter.
From single incidents to portfolios, our operating model adapts without rebuilding from scratch.
