Cloud Security & IAM Case Study

The Client

A leading electric distribution company in Argentina, serving approximately 9 million residents across 20 districts in Greater Buenos Aires and the Autonomous City of Buenos Aires.

The Challenge

Operating in a highly regulated and business-critical environment, the organization needed to significantly improve its security posture and governance framework. Key challenges included:

Lack of standardized security practices across a complex infrastructure
Need to comply with SOX regulations
Limited governance over access control and change management processes
Exposure to operational and security risks
Need to enforce least privilege access across all services
Lack of centralized monitoring, logging, and audit capabilities

The organization required a structured approach to enhance security, ensure compliance, and improve traceability and incident response.

The Solution

Netrix implemented a comprehensive security transformation program aligned with AWS best practices and enterprise governance requirements. Key components included:

AWS Security Journey Assessment aligned with the Well-Architected Framework (Security Pillar)
Delivery of a prioritized remediation roadmap and executive-level security insights
Implementation of AWS WAF to strengthen perimeter security
Deployment of Amazon GuardDuty for threat detection
Establishment of SOX governance and compliance controls
Definition of new IAM policies, roles, and governance model enforcing least privilege
Centralization of logs and audits to support Security Operations Center (SOC)

Identity & Access Architecture

AWS IAM for fine-grained access control
AWS IAM Identity Center for centralized workforce access
AWS Organizations to enforce multi-account governance and guardrails
AWS Directory Service integration with corporate identity systems

Customer Identity & Access (CIAM)

Amazon Cognito for customer authentication
Amazon Verified Permissions for fine-grained authorization policies

The Implementation

Initial assessment to identify gaps and high-risk areas
Structured remediation aligned with AWS security standards
Phased implementation of security controls and governance
Integration of monitoring, logging, and incident response capabilities
Establishment of a scalable, multi-layered identity and access model

The Results

Outcome Area	Delivered
Security Posture Improvement	40% improvement in security maturity Reduction of 85 critical security findings to zero
Risk Reduction & Threat Detection	Early detection of vulnerabilities and threats in exposed applications Reduced operational and security risk
Governance & Compliance	Implementation of centralized security governance Alignment with SOX requirements and AWS best practices Full traceability through integrated logging and audit systems
Operational Efficiency & Scalability	Improved incident response times Standardized and auditable security framework Enhanced scalability through structured, multi-account architecture
