Protecting the Systems That Keep a 24/7 Food Supply Moving
Refrigerated trucks that keep temperature-sensitive food and perishables moving rely on systems protected by Zero
Operational demands with zero tolerance for downtime
Secured across CRE’s complex hybrid network spanning on-prem data centers and a large fleet of endpoints
“Zero Networks gave us a level of visibility we hadn’t had before – both in what our network is actually doing and in our ability to stop malicious activity from spreading.”
Challenge
A leading American logistics and trucking company, C.R. England (CRE) has kept essential operations moving for more than 100 years. But like many large enterprises that grew rapidly over decades, C.R. England’s security team inherited a flat, largely unsegmented network with limited visibility.
Manually maintaining thousands of rules across a constantly changing environment and a network of CRE’s size wasn’t just difficult – it was functionally unsustainable for the growing needs of the business.
C.R. England needed a way to implement granular lateral movement control and gain comprehensive visibility into network activity, enabling scalable security in an environment with extreme uptime standards.
Solution
C.R. England turned to Zero Networks for a single platform that could answer three questions simultaneously – what is talking to what, what accounts are authenticating where, and what RPC operations are being called by whom – before enforcing controls on any of them.
Zero’s automated learning engine surfaced previously hidden risks, giving CRE’s security team real-time, end-to-end visibility into assets, identities, and communication paths before tailoring granular access policies to real network behavior.
By combining identity-based microsegmentation, RPC segmentation, and just-in-time MFA enforcement on every privileged access path, CRE closed long-standing security gaps without disrupting critical operations.
Result
With Zero Networks, C.R. England uncovered the first accurate, evidence-based picture of communication patterns across their datacenter – including services that had never been documented. Zero’s automated learning period delivered a complete service dependency map and exposed risky service account sprawl, enabling CRE to enforce granular access controls that automatically contain unauthorized lateral movement.
Administrative access to production servers now requires just-in-time MFA verification and east-privilege enforcement is grounded in observed behavior rather than stale provisioning decisions, proactively constraining blast radius while meeting uptime standards.
Stop lateral movement, start your weekend.
