The 5 Questions Every Leak Investigation Needs to Answer
In this video, you will learn the five questions every data leak investigation must answer to be defensible — what the data is, where it originated, who accessed it, where it spread, and the fastest containment step — and why the visibility gap in most security stacks makes those questions impossible to answer instantly. You will also learn how combining DSPM baseline inventory with real-time data lineage replaces the high-stress scramble with surgical containment and audit-ready proof, so you move from "I think we're safe" to "here is the proof."

Q: What are the five questions every leak investigation must answer?
A: A defensible investigation answers what the data is, where it originated, who accessed it, where it spread, and what the fastest containment step is. If you can answer all five in real time, you have governance. If you cannot, you have a collection of noisy tools and you are guessing rather than investigating.
Q: Why isn't a "Confidential" label enough to assess a data incident?
A: Generic tags and regex patterns generate massive false positives because they match strings without understanding context. Knowing a file is marked confidential does not tell you whether it holds PII, unreleased financials, or core source code. If your investigation begins by manually opening a file to verify its contents, the strategy has already failed.
Q: Why does data provenance matter more than the destination?
A: Provenance drives risk scoring. A file uploaded to a personal drive might be a minor policy violation, but the same file originating from a core engineering repository is a critical incident. Traditional logs show the destination but rarely the source, so without provenance teams burn out chasing low-risk events while high-value data leaves the building.
Q: Why do legacy DLP tools lose track of data as it moves?
A: Legacy tools rely on file hashes and metadata, which break the moment a user renames a file or copies text into a new document. A sensitive Excel doc copied to the clipboard, pasted into an AI tool, and saved as a renamed PDF looks like a clean new file because the hash changed, even though the sensitive content is identical. Tracing lineage as data morphs across applications captures the full scope a hash-based tool misses.
Q: How does data lineage make compliance audits defensible?
A: Instead of handing an auditor a 40-page CSV of disjointed logs, lineage produces a single graph that visually demonstrates every step the data took and exactly where it was stopped. This turns a homework assignment into defensible proof that controls are working, letting you prove compliance with certainty rather than hoping you passed.
