01
Exposed surface
Issue
Remote access, vendors and network flows remain permeable even after the assessment.
Solution
Introduces zones, conduits and filter rules coherent with the real OT context.

Infrastructure Protection
When protecting without stopping production
OT protection is needed when the baseline is clear but a coherent design of segmentation, access and monitoring sustainable by the plant team is still missing.
02
Sustainable hardening
Issue
Configurations and technical baselines are not aligned with real operational windows.
Solution
Plans hardening in phases compatible with plant continuity.
03
Operational monitoring
Issue
Without monitoring routines and runbooks, signals and deviations remain invisible.
Solution
Defines procedures, escalation paths and checkpoints to react in an orderly way.
operating method
How we work: 4 progressive measures in sequence
01
Segmentation design
Network segmentation design following the IEC 62443 zones/conduits model.
02
Implementation
Configuration of industrial firewalls, VLANs, DMZ and inter-zone access policies.
03
Monitoring and detection
Deployment of OT network monitoring solutions for anomaly and threat detection.
04
Incident response plan
Definition of OT incident response procedures: escalation, containment, recovery.
expected output
What we build to protect OT infrastructure
We translate assessment findings into concrete measures, sustainable configurations and monitoring routines the team can maintain.
Configurations, access, services and technical baselines to strengthen without breaking operations.
Procedures, escalation paths and checkpoints to react in an orderly way to signals and anomalies.

// design.segmentation
Segmentation design
analisi: Definition of zones, conduits and filter rules between OT and IT levels.
criticità: Flat architectures, permissive rules, missing isolation between critical areas.
output: Target design with industrial firewalls and verifiable rules.
// design.hardening
Hardening baseline
analisi: Standard configurations for HMI, servers, switches and industrial devices.
criticità: Heterogeneous configurations, default passwords, unnecessary services.
output: Progressive technical baseline, applicable in phases.
// ops.remote_access
Secure remote access
analisi: Vendor, maintainer and internal team access to plants.
criticità: Always-on VPNs, shared accounts, missing logs.
output: Jump host + MFA + centralized log model.
// ops.monitoring
Monitoring and runbook
analisi: Relevant events, thresholds, escalation and response procedures.
criticità: Lost signals, ambiguous roles, ad-hoc reaction.
output: Shared runbook with clear escalation and checkpoints.
