# Overview

Nightfall helps organizations secure historical data in Google Drive through comprehensive DLP audits. The platform offers two audit types to enhance your data security posture:

1. **Posture Management**: Focuses exclusively on file permissions, identifying files with risky sharing configurations like external user access or public sharing.
2. **Posture Management & Data Discovery**: Provides complete protection by examining both file permissions and content for sensitive information like PII, PCI, PHI, secrets and credentials.

### Key Functionality

* **Customizable Scope**: Select specific drives, date ranges, and permission settings to target your audit.
* **Automated Remediation**: Configure actions that trigger automatically when violations are reported.
* **Comprehensive Scanning and Visibility**: Examines over 150+ file types using AI-powered detection. Review violations in the console and metrics such as total data scanned, highest risk users, assets and more.

## Prerequisites

You must ensure that the Google Drive integration is installed in your Nightfall tenant. To learn more about how to install the Google Drive integration, refer to this [Nightfall documentation](https://help.nightfall.ai/google-drive/getting_started/installation).
