01
THE CHALLENGE

Create global security visibility and a repeatable incident-response model across distributed multinational operations.

02
THE CONTEXT

Regional technology and security teams operated across more than 10 countries with telemetry from cloud, endpoints, identity and on-premises environments.

03
THE STRATEGY

Prioritize telemetry, use cases, correlation, investigation, escalation and operational integration rather than treating SIEM as a standalone tool deployment.

04
THE ARCHITECTURE

Centralized Microsoft Sentinel and Splunk architecture integrating security telemetry, correlation rules, dashboards, alerting, investigation workflows and IAM-related processes.

05
THE IMPLEMENTATION

Rolled out the monitoring architecture, dashboards, correlation, escalation procedures and automated incident-response processes across multinational operations.

06
SECURITY & GOVERNANCE

Connected SIEM operations to NIST, ISO 27001, IAM, PAM, MFA, RBAC, vulnerability management, audit and incident-management practices.

07
RESULTS

Expanded threat visibility and contributed to an approximately 45% reduction in critical incident response time across multinational operations.

08
LESSONS LEARNED

A global SIEM program succeeds when detection, investigation, ownership and escalation are engineered as one operating model.
