The Client

One of Argentina's largest electricity distributors serves more than 3 million customers and provides approximately 20% of the country's electricity supply. As part of the nation's critical infrastructure, the company operates in a highly regulated environment where reliability, security, and compliance are essential.

The Challenge

Following a major security breach caused by a misconfigured cloud environment, the company suffered the deletion of resources across 28 AWS accounts, disrupting critical systems and business operations. Key challenges included:

  • Recovering from a large-scale cloud security incident
  • Restoring business operations rapidly
  • Building a secure multi-account AWS environment
  • Improving security governance and compliance

  • Amazon GuardDuty for threat detection
  • AWS Inspector and Detective for vulnerability management and investigation
  • AWS Firewall Manager and AWS WAF implementation
