Case Study: a large integrated delivery network achieves zero-downtime network segmentation with Cerecore

a large integrated delivery network achieves zero downtime segmentation with Cerecore

The customer, a large integrated delivery network, faced a complex cybersecurity challenge due to a flat network that lacked segmentation and visibility into east-west traffic. This posed a significant risk to its clinical systems. The organization needed to implement enterprise-grade network segmentation across its two active data centers without causing any downtime or user impact, all within a compressed timeline. They engaged CereCore for its IT infrastructure and networking services.

CereCore implemented a segmentation solution by first performing automated network discovery and analyzing over 500,000 traffic flows to create a streamlined firewall ruleset. Using a healthcare-aware, phased deployment strategy with firewalls initially in monitoring mode, CereCore delivered the project with zero downtime, zero user disruptions, zero performance degradation, and zero support tickets. The work was completed 30 days ahead of schedule, significantly strengthening the organization's security posture and operational visibility.
