Global OT-Security and Network Monitoring Rollout

Network Security OT-Security

  • Takeover of the project, at a point, where less than 3 months were left until the shareholders expected to have the activity closed
  • Development of the required high-level network changes, alignment with global sites and creating the detailed action plan and management of change documents
  • Fast-track selection and procurement of missing hardware parts and handling the global delivery
  • Performing rollout at all sites and integration into the Azure dashboards of the customer
  • Phase 1 was delivered a week ahead of time with 100% of the sites onboarded (instead of expected 70%)
  • Phase 2 (after June 2023) was concerned with optimization of the visibility into the OT networks and defining alerts for the SOC
  • Also afterwards different additional measures like hardening were implemented
