CASTEL GROUP
Renaming, Standardisation and implementation of a MCO for over 100 firewalls.
Context
The CASTEL group had a park of over 100 firewalls managed in a heterogeneous way, with non-uniform rules and nomenclature. This situation complicated daily management and network security monitoring across all sites.
Requirements
Implement a unified naming and configuration convention for all firewalls.
Simplify maintenance and support, while enhancing visibility into network status.
Ensure reactive and appropriate MCO (Maintenance in Operational Conditions) for such a large fleet.

Approach

Approach
Initial Audit Analyse of the existing situation (names, rules, configurations) and survey of each site's needs to define a suitable standard.
Standardisation Development of a naming and configuration charter, integrating network segmentation, security best practices, and CASTEL requirements.
Rename Phased deployment of the new nomenclature, correction of obsolete rules and alignment of configurations.
MCO Implementation of centralised supervision, 24-hour support and a rapid alert process to effectively handle requests and incidents.
Performance Implementation of SLAs for support and resolution times based on priority, urgency, and complexity.

Results
Simplified management A clear naming convention makes it easier to identify equipment and resolve requests and incidents across the entire network.
Enhanced security Harmonised and updated rules reduce vulnerabilities and improve traceability of changes.
Downtime reduction A reactive and structured MCO prevents prolonged interruptions and limits operational impact.
Increased visibility Centralising configurations and incident reports provides a better understanding of the overall network status.
