Hardening a sprawling factory network

The Challenge

Years of organic growth left the client with flat network segments, ageing firewall rules and undocumented OT devices bridging the corporate and plant networks.

Our Approach

We audited the architecture, firewall rulebase, wireless and VPN against CIS benchmarks, mapped IT/OT trust boundaries, and delivered a prioritised segmentation and hardening roadmap.

The Outcome

The client implemented proper IT/OT segmentation, cleaned up its firewall estate and adopted a repeatable hardening baseline — dramatically shrinking the blast radius of any future compromise.
