Personal Data Discovery: Find Where a Person's Data Lives Across Your Systems
The hardest part of a DSAR is not writing the reply, it is finding every place a person's data actually lives. Obtainer is a personal data discovery tool that surfaces those locations across your systems and compiles them into one reviewable manifest you can work from.

Helps you comply, not legal advice
In short
Personal data discovery is the work of finding every place an organization holds data about a specific person so you can answer a data subject access request completely. It is the real gap most teams cite, because personal data is scattered across CRMs, help desks, email, files, and databases, and missing a source means an incomplete response. Obtainer is a personal data discovery tool that surfaces where a person's data lives across your systems and compiles it into one source-system manifest you can review, so you see the full picture in one place instead of hunting through each tool by hand. Every record stays behind a human redaction gate, so you stay in control of what is disclosed and nothing is released automatically. Obtainer helps you comply. It is not legal advice, and the judgment of what is in scope stays with your team. It is self-serve DSAR fulfillment from $49/mo, focused on discovery and drafting rather than a sprawling governance suite like OneTrust or DataGrail.

What you get
Data discovery, built for privacy, legal, and ops teams
Close the completeness gap
Discovery completeness is the gap buyers cite most. Obtainer surfaces where a person's data lives so a source is less likely to be missed.
One reviewable manifest
Every located record rolls into a single source-system manifest, so you see everything in one place instead of stitching exports together.
Source badges you can trust
Each item is tagged with the system it came from, so your team can trace, verify, and decide what belongs in the response.
Findings, not disclosures
Discovery surfaces data for your review, it does not release it. A human redacts and approves before anything is disclosed.
How it works
From an intake request to a ready-to-review response in four steps
Start from a verified request
Begin discovery only after the requester is confirmed, so you gather data for the right person.
Surface the locations
Obtainer finds where the person's personal data lives across your systems and lists each source.
Compile the manifest
Every located record is compiled into one reviewable manifest with source badges, so nothing sits in a silo.
Hand it to review
Your team reviews, redacts, and decides scope. Obtainer helps you comply. It is not legal advice.
Frequently asked
Questions teams ask about data discovery
What is personal data discovery?
Personal data discovery is the work of finding every place an organization holds data about a specific person, so you can answer an access or deletion request completely. It spans structured systems like CRMs and databases and unstructured stores like email and files. Missing one source means an incomplete response, which is the most common way a DSAR goes wrong.
How do you find all of a person's data across systems?
You either search each system by hand, which is slow and easy to leave gaps in, or you use a tool that connects to your systems and surfaces where the person's data appears in one pass. Obtainer discovers those locations across your connected systems and compiles them into a single source-system manifest you review, rather than hunting tool by tool.
What is the difference between data discovery and data mapping?
Data mapping is a standing inventory of what data types you hold and where, kept up to date for governance. Data discovery, in a DSAR context, is finding one named person's data right now to answer their request. A map helps, but people's data moves and copies, so a live discovery pass is what makes a specific response complete.
Does data discovery delete or change my data?
No. Discovery only locates and lists where a person's data lives; it reads, it does not act. Nothing is disclosed, deleted, or altered from the discovery step. A human reviews the manifest and approves any disclosure or erasure at a separate gate, so you stay in control of what is released or removed.
Run a data subject access request end to end
Obtainer finds where a person's data lives across your systems, compiles it into one manifest, drafts the deadline-safe response, and tracks the GDPR and CCPA clock. You review, redact, and approve what gets disclosed. Helps you comply; not legal advice.
