CASE STUDY 001 · DATA PROTECTION
Reducing false positives without losing SSN coverage
Problem. Generic nine-digit pattern matching flags reference numbers along with potential customer identifiers.
Approach. Combine format checks with surrounding field context, destination risk, and verified business use; evaluate precision and misses on a labeled synthetic corpus.
Tradeoff. Contextual detection improves specificity but can miss data in unusual exports. Introduce staged audit and block policy changes with exception governance.

From DLP alert to evidence-based exfiltration assessment
Problem. A high-severity content match does not demonstrate that a sensitive file left the environment.
Approach. Correlate DLP control outcomes with web/email delivery, endpoint operations, identity activity, file metadata, and approved destinations.
Tradeoff. Telemetry gaps, asynchronous logging, and exceptions can change confidence. Report confirmed, attempted, and unknown outcomes separately.

Designing an exception review lifecycle
Problem. Permanent exemptions weaken controls while requiring engineers to judge business necessity beyond their context.
Approach. Identify a business owner, record scope and expiry, route approvals, review continued need, and revoke stale exceptions.
Tradeoff. Efficient approval needs auditability and least privilege without bypassing appropriate data-owner judgment.
