BigID gives security teams real-time visibility into sensitive files uploaded to or accessed by Claude, so teams can detect exposure the moment it happens.
Discover, classify, and understand the sensitive data employees share with Claude. Identify exactly what information was uploaded, who uploaded it, and respond before AI data exposure becomes a security incident.
BigID connects to Claude combining real-time activity data from Claude with BigID's classification engine. The result is a continuous, accurate record of what's being shared with Claude, and an automatic alert whenever that data is sensitive.
The Problem
Sensitive data is moving into Claude
with no oversight.
Claude has become part of everyday workflows. Employees upload spreadsheets, contracts, financial reports, customer records, and other business files to speed up analysis, drafting, and decision-making.
Sensitive data enters Claude unnoticed
Employees can share business-critical data with Claude before security teams know it happened.
Security teams don't know what was exposed
Without monitoring, teams may not know who shared the file, when it happened, or what Claude could access.
Risk isn't the file—it's what's inside it
Spreadsheets, contracts, reports, and customer files can contain PII, financial data, secrets, or confidential information.
Investigations start from zero
When an incident occurs, teams need a clear answer to what Claude accessed and what sensitive data was involved.
The Solution
BigID's Claude integration delivers
real-time visibility into sensitive data.
BigID combines real-time Claude activity with BigID’s classification engine, giving security teams a continuous record of what is shared with Claude and automatic alerts when that data is sensitive.

What Makes BigID Different
Go beyond upload monitoring
with classification depth.
BigID does more than tell teams that a file moved into Claude. It helps analysts understand what sensitive data was inside, who shared it, when it happened, and whether Claude accessed or referenced it.
Know exactly what was exposed
Identify the exact sensitive attributes inside a flagged file, including PII, financial records, regulated data, and confidential business information.
Not every file is equally risky
Monitor files Claude accesses or references, not only files directly uploaded by a user.
Understand the full scope of exposure
Trigger security alerts the moment a sensitive file interaction with Claude occurs.
Investigate with complete context
Give analysts timestamp, user, file, activity, and sensitive data context without manual follow-up.
Monitoring Claude Activity in BigID
Understand every sensitive file
shared with Claude.
Activity Explorer provides a complete history of sensitive files uploaded to Claude, helping teams understand exposure over time, support investigations, and demonstrate compliance.
✓
Track every sensitive upload
See every file uploaded to Claude alongside the user, timestamp, and activity details, creating a complete record of sensitive data shared with AI.
✓
Know exactly what was exposed
Automatically classify each uploaded file to identify the sensitive attributes it contains, including PII, financial records, regulated data, intellectual property, and confidential business information.
✓
Support investigations
Reconstruct incidents with a chronological history of uploads, users, file activity, and sensitive data context so analysts can quickly understand the scope of exposure.
✓
Simplify compliance audits
Provide an exportable audit trail showing when sensitive data was shared with Claude, who shared it, and the business context needed for compliance reporting.
✓
Prioritize response
Focus investigations on the uploads that matter most by combining sensitive data classification, user activity, and policy-based alerts to reduce AI data risk faster.
Automatic Alerts
Sensitive Claude uploads
flagged the moment they happen.
BigID includes a built-in policy, Sensitive File Upload to Claude, that continuously monitors activity and triggers a security alert when sensitive data is uploaded to Claude.
Timestamp
Know exactly when the sensitive file was uploaded or accessed.
User
Identify who uploaded or shared the file with Claude.
File Details
See what was shared and open a live preview in the BigID Data Catalog.
Sensitive Attributes
Understand exactly which sensitive attributes are present, enabling faster response.
Before and After BigID
Replace Claude blind spots
with real-time control.
BigID helps security teams move from guessing what sensitive data was shared with Claude to knowing exactly what was uploaded, who uploaded it, what was exposed, and what needs action.
Sensitive Data Visibility
Sensitive files enter Claude unnoticed.
Sensitive uploads are identified immediately with data classification context.
Exposure Context
Security teams do not know what sensitive data was exposed.
Teams can see exactly which sensitive attributes were shared, including PII, financial data, regulated data, and confidential information.
Manual Review
Analysts manually inspect files after the fact to determine risk.
BigID automatically classifies uploaded files and flags sensitive data as activity occurs.
Investigations
AI investigations lack clear evidence, ownership, and timeline context.
Every sensitive upload includes timestamp, user, file activity, and classification context for faster investigation.
AI Risk Response
Security teams react to AI data exposure after risk has already spread.
Teams prioritize response based on sensitive data, user activity, and policy-based alerts.
