## Description

Control how files are shared externally in Google Chat and Hangouts.

## Rationale

Files often contain confidential information, and some organizations, particularly in regulated industries, need to control the flow of this information within and outside of their organization.

## Impact

Users will not be able to share files via chat externally.

## Audit Procedure

1. Log in to https://admin.google.com as an administrator
2. Select `Apps`
3. Select `Google Chat and classic Hangouts`
4. Select `Chat File Sharing`
5. Under `Setting`, verify `External filesharing` is set to `No files`

### Expected Result

`External filesharing` should be set to `No files`.

## Remediation
