Why It Matters

The core goal is to immediately remediate any exposed customer data within your Azure environment, ensuring compliance with GDPR requirements and protecting customer privacy. Fixing customer data exposure in Azure is critical for organizations handling EU customer information, as it helps you respond to potential data breaches within the required 72-hour notification window and implement proper access controls.

Primary Risk: Data exposure of customer information

Relevant Regulation: GDPR (General Data Protection Regulation)

Swift remediation prevents regulatory fines, maintains customer trust, and establishes a framework for ongoing data protection compliance.

Prerequisites

Permissions & Roles

  • Azure Security Administrator or Contributor
  • Storage Account Contributor privileges
  • Azure Policy Contributor access

External Tools

  • Azure CLI or PowerShell
  • Cyera DSPM account
  • Microsoft Purview account

Prior Setup

  • Azure subscription active
  • Resource groups configured
  • Network security groups defined
  • Identity and access management configured

Introducing Cyera

Cyera is a modern Data Security Posture Management (DSPM) platform that discovers, classifies, and continuously monitors your sensitive data across cloud services. Using advanced AI and Named Entity Recognition (NER) models, Cyera automatically identifies customer data patterns, assesses exposure risks, and provides actionable remediation workflows to ensure Azure environments remain GDPR-compliant and secure.

Step-by-Step Guide

1
Assess the exposure scope

Use Cyera's AI-powered discovery to identify all locations where customer data is exposed. Review access logs, storage account permissions, and network configurations to understand the full impact.

az storage account list --query "[].{name:name, resourceGroup:resourceGroup}"

2
Implement immediate containment

Revoke public access permissions, update network security group rules, and apply Azure Policy restrictions to prevent further exposure. Use Azure Private Endpoints where appropriate.

3
Apply data protection controls

Enable Azure Storage encryption, configure Azure Key Vault for key management, and implement Microsoft Purview Data Loss Prevention policies to prevent future exposures.

4
Monitor and validate remediation

Set up continuous monitoring with Cyera to ensure the exposure has been fully remediated. Configure alerts for any new customer data discoveries and establish automated response workflows.
