A leading Italian energy operator
An integrated network infrastructure, built on MPLS and SD-WAN, that holds together more than 100 sites and the most critical production plants, with the operational resilience and centralised visibility an energy infrastructure demands.
Italian energy operator
Integrated management of critical infrastructures for energy production and distribution across a distributed territorial footprint.
It is one of the leading operators in the national energy sector, with an organisation spanning multiple operating entities and more than 100 sites distributed across the country. Behind this scale lies the daily management of critical infrastructures for energy production and distribution: numerous production sites and a dense network of interconnections, where reliability and operational continuity are not a goal but a prerequisite.

The industry scenario
According to the Cybersecurity & Data Protection Observatory of the Politecnico di Milano, centrally managed SD-WAN and MPLS architectures significantly shorten the time to detect network anomalies and strengthen the overall resilience of the infrastructure — decisive factors for those operating on distributed, critical assets.

Challenge
Resilience across a distributed infrastructure
For the group, operational continuity is not a technical topic but a strategic necessity: the proper functioning of production activities and the resilience of critical infrastructures that cannot afford downtime depend on it. What makes the picture complex is the sheer scale of the perimeter — more than 100 sites distributed across the country — and the need to make them work as a single system: interconnected, reliable and governed from one centre.
Areas of intervention
The complexity is concentrated on four closely interlinked fronts:
More than 100 distributed sites
The starting point is the size of the perimeter: more than a hundred sites scattered across the country, to be brought back into a single coherent infrastructure instead of many separate networks to manage one by one.
Stable, secure interconnection between sites and data centers
Connecting the sites to the data centers continuously and securely, so that data travels without interruptions and without exposure along the way.
Reliability, resilience and continuous monitoring
High availability standards, the ability to withstand failures and constant oversight of the network, to catch and resolve anomalies before they affect operations.
Unified, centralised management
Governing network and security from a single point, with consistent policies across all sites, instead of fragmented site-by-site management.
Retelit's solution
An integrated, redundant network infrastructure for operational continuity
Retelit designed a dual-track network architecture that brings MPLS and SD-WAN into dialogue over a complex, distributed infrastructure base. The goal: to provide resilience where it is needed, restore visibility over everything and ensure that operational continuity does not depend on a single path.
Services activated and technologies
Network infrastructure
MPLS and SD-WAN with redundant architectures
The MPLS network connects around 50 peripheral sites in a primary-secondary logic, with triple connectivity on the most critical sites; the SD-WAN network covers just as many sites with a similar structure, adding dynamic optimisation of application traffic. Both converge on the primary and secondary data centers and, thanks to multi-link and alternative paths, stay up even when one route is interrupted.
Managed services
Proactive monitoring and unified management
Retelit centrally oversees the entire network infrastructure and the data centers, with real-time visibility over performance and anomalies and full management of the devices across every perimeter. Firewalls and security policies are governed from a single point, simplifying control over a wide, fragmented geographical footprint.
Security and governance
Unified perimeter protection and end-to-end control
Traffic protection is end-to-end, with policies applied uniformly across all sites: an approach that reduces the risk of critical service disruptions and meets the stability standards that a complex energy infrastructure cannot negotiate.
Results
Operational resilience and centralised visibility across a distributed infrastructure
With a single integrated network infrastructure, the group oversees more than 100 sites and its data centers as one system: operational continuity becomes a starting condition and monitoring shifts from reactive to proactive.
On critical sites, redundant multi-link architectures hold up even in the event of a failure: the risk of disruption is reduced and communications between the periphery and the data centers remain stable.
Centralised visibility over performance, anomalies and device status makes it possible to intervene before a problem manifests, cutting resolution times.
Dynamic traffic optimisation and simpler provisioning make the network more efficient and quicker to adapt when demand changes.
Managing firewalls and security policies from a single point, across all sites, strengthens perimeter protection and keeps regulatory compliance aligned.
