The real workflow
Where Gemini enters the work
Agency teams may connect several client mailboxes, drives, knowledge sources, and project systems to a common assistant workflow.
Gemini can work with prompts, uploads, live audio or screen context, and connected Google or third-party services depending on device, account, region, and settings.
Client content may enter through uploads, connected Google services, live screen sharing, or a work account whose policies differ from a personal account.
Gemini access is shaped by what the user shares, device permissions, connected apps, Gemini Apps Activity, and other Google settings that may remain active independently.
The presence of this path does not prove an incident. It identifies the boundary that should be checked before more sensitive context or authority is added.
Tool-specific boundary
Inspect the real access points.
What may carry context
prompts, files, images, audio, video, and shared screens
connected Google and third-party apps
device permissions and Gemini Apps Activity
Settings to verify
Gemini Apps Activity and auto-delete
Connected apps and public links
Google app device permissions and Saved Info
Why this context matters
The consequence for agencies
Agency risk compounds when staff, contractors, shared tools, and reused credentials create paths between otherwise separate client environments. In this case, exposure can trigger contractual disputes, notification duties, account reviews, project delays, and costly investigation even when no malicious intent was involved.
Client data is not yours to expose simply because it helps complete a task. The practical question is whether the client authorized this tool, this account type, this data category, and this specific access path.
Every client remains isolated, access is attributable to a named operator, and the agency can deliver consistent evidence without revealing another client.
Context decision
Three questions before adding access
Can this operator or tool reach any repository, mailbox, drive, cache, token, or transcript belonging to another client?
Are credentials and AI sessions issued per client and person rather than shared across the agency?
Can the agency deliver useful proof to this client without including another client's names, paths, findings, or configuration?
Evidence goal: Create a separate client evidence record covering operator identity, workspace isolation, credentials, approved systems, review history, and delivery status.
A repeatable review
Four steps, no sensitive data required
- 1
Write down the exact Gemini account, workspace, project, device, and connected service used in this workflow.
- 2
Confirm which Google account is active, what Keep Activity does, and whether the client approved connected-app use.
- 3
Assign the decision and next review to the client service owner or agency security lead; do not leave the access boundary as an unwritten assumption.
- 4
Use a dedicated work profile with minimized permissions and synthetic client examples. Record the result without copying private content or raw credentials into the report.
Controls to apply
Reduce access before adding trust
Use a dedicated work profile with minimized permissions and synthetic client examples.
Use separate client workspaces and least-privilege accounts instead of one shared personal AI context.
Minimize, redact, or synthesize data before it reaches the assistant.
Keep a simple register of approved tools, client constraints, access dates, and deletion steps.
Decision rule
Know when a formal baseline is justified
If a task contains client-confidential material, do not proceed on assumptions. CapitalGuard becomes useful when the work also involves repositories, connected tools, repeat client workflows, or evidence that must be shown back to the client.
CapitalGuard is relevant when the workflow includes repositories, recurring private work, credentials, connected systems, commands, or evidence that must be shared with another person. It does not inspect this account from the page or guarantee that an incident cannot occur.
