See what Copilot, Gemini, ChatGPT Enterprise and Claude would surface before rollout, and keep them scoped after go-live.
An assistant answers with whatever each user can already open. BigID maps that reach, fixes the oversharing and unlabeled sensitive data inside it, and gives security the evidence to sign off the rollout.
Broad links, external shares, stale guests and unlabeled sensitive files, mapped to the people who can open them
Through go-live
Oversharing fixed at the source
Access right-sized, labels synced to Microsoft Purview, stale data disposed, and exclusions set for what stays off-limits
After launch
The assistant kept in scope
New shares, new sensitive data and new agents caught as they appear, with activity tracked for people and agents alike
Where AI assistant rollouts are now
An assistant is as well scoped as the access underneath it
Copilot, Gemini, ChatGPT Enterprise and Claude retrieve through each user's existing permissions, so years of broad sharing, inherited access and unlabeled sensitive files become answerable in a sentence. The rollout is usually already on the calendar, and several teams have a stake in it. BigID runs readiness as one project from one view of sensitivity, access, identity and AI assets, so each of them works from the same findings.
For IT and the Microsoft 365 or Workspace team
A rollout that moves in phases. Readiness by site, department and data type shows where the assistant can go live now, so licenses reach users while remediation continues behind them.
For security
Evidence to sign off, and controls after. What each assistant can reach, what was fixed at the source, and the monitoring that keeps reach small once everyone is switched on.
For privacy and AI governance
Assessments grounded in the real data. AI and privacy assessments per use case, exclusions for the material that stays out of answers, and the agents built on each assistant inventoried.

BigID Fine-Grained Access Control Demo: Review Permissions & Reduce Data Exposure
Reviewing who can reach sensitive files, down to the individual permission, then tightening access before an assistant can surface it.
The rollout already on the calendar, with BigID at every stage
Readiness work runs alongside the rollout plan. Exposure is measured at assessment and brought down before the pilot, the pilot tests what real users can retrieve, and after go-live the same controls keep reach small as data and access keep changing.
By assistant
Ready for every assistant the business adopts
Each assistant reaches data through its own connectors, and all of them respect the permissions underneath. Fixing access, labels and stale data at the source readies the estate for every one of them, and BigID assesses each assistant's reach on the same findings.
Microsoft 365 Copilot
Microsoft Graph: SharePoint, OneDrive, Exchange, Teams, plus Copilot connectors and Copilot Studio agents
Oversharing and broad links found across SharePoint and OneDrive
Labels synced into Purview Information Protection for Purview DLP to enforce
Sources behind third-party connectors assessed too
Gemini for Google Workspace
Drive, shared drives, Gmail, Docs, Sheets and Slides, through Workspace sharing
"Anyone with the link" and domain-wide sharing found and closed
Sensitive files in shared drives classified and ranked
Access activity on Drive monitored after go-live
ChatGPT Enterprise
Connectors to sources such as SharePoint, Google Drive, Box and Dropbox, plus uploaded files and custom GPTs
Every source behind an enabled connector assessed for exposure
Sensitive data kept out of files and knowledge that users upload
Custom GPTs inventoried with the data they draw on
Claude
Connectors and MCP servers to sources such as Google Drive, Microsoft 365 and Slack, plus project knowledge
Sources behind each connector and MCP server assessed for exposure
Project knowledge checked for sensitive content before it is shared
BigID itself operated from Claude over MCP, for reports and remediation
Capabilities
Everything the readiness project needs, from first assessment to steady state
Assistant readiness draws on access governance, data security posture, lifecycle management and AI governance. BigID runs them as one project on one set of findings, so what the assessment finds is what remediation fixes and what monitoring keeps fixed. Each group links to the hub with the full detail.
Oversharing and exposure assessment
Start with what a prompt could return. BigID compares actual access with intended access across every source an assistant can index, classifies the sensitive data inside, and shows where the two overlap, by user, team and department.
Broad links and external shares revoked, and access right-sized in bulk or file by file
Access reviews delegated to data owners, with each attestation recorded
Sensitivity labels applied from classification and synced into Microsoft Purview
AI exclusions for legal holds, investigations and M&A, whatever the permissions
Redundant, obsolete and trivial data disposed of, so there is less to search and surface
Assistant, connector and agent governance
An assistant arrives with connectors, and soon with agents built on top of it. BigID inventories them with the identity each runs under and maps what each can reach.
Assistants and models in use discovered, sanctioned and shadow
Agents and connectors built on each assistant inventoried, with the identity each runs under
What each agent can reach mapped against what its function requires
AI-generated content classified, with retention and access matching its sources
AI and privacy assessments per use case, aligned to the EU AI Act and the NIST AI RMF
Post-rollout monitoring and response
Data and access keep changing after go-live. BigID replaces the one-time cleanup with continuous controls for people and agents.
Access activity monitored across the sources an assistant reads
Unusual behavior flagged for users and for agents
New broad shares, sensitive files and agents checked against policy as they appear
Access revoked dynamically, without waiting for the next review
Agents that investigate an exposure and remediate it, from BigID or from the assistant itself
Readiness reporting for the go/no-go
The rollout needs a sign-off, and the board will ask how it is governed. BigID shows where the assistant can go live now and the evidence behind each decision.
Readiness by site, department and data type
Exposure trends from assessment through steady state, for the steering committee and the board
Evidence for auditors: what was reachable, what changed, and who approved it
Reports asked for in natural language, from BigID or over MCP
Coverage
Every source an assistant can index
An assistant's reach is the sum of its connectors. BigID covers the sources they draw on, across Microsoft, Google, collaboration apps, file shares, cloud and the AI data stores behind retrieval.

Before you commit
What CISOs ask before signing off the rollout
We already run Microsoft Purview. What does BigID add?
BigID works with Purview and extends its reach. Discovery and classification cover the sources beyond Microsoft 365 that an assistant also draws on, labels sync into Purview Information Protection so Purview policies enforce them, access and activity context sits beside every finding, and enriched signals flow into Purview DSPM.
We are rolling out more than one assistant. Do we repeat this for each?
The core work is done once. Every assistant retrieves through the same permissions, so fixing access, labels and stale data at the source readies the estate for all of them. Each assistant's connectors add sources, and BigID assesses readiness per assistant on the same findings.
Our go-live date is fixed. Where do we start?
With the sites and departments that carry the most sensitive data. The readiness view shows where the assistant can go live now and where remediation comes first, so the rollout can proceed in phases while exposure is brought down behind it.
