Securing IoT devices across foundry and fabrication operations.

A global mining operator runs essential operations on IoT devices (controllers and sensors) across foundries and fabrication systems. BTA deployed Cisco Secure Workload with ERSPAN collectors to secure the IoT estate without disrupting production.

The problem

IoT devices were connected to the corporate network, and the team lacked visibility into traffic flows. Without that visibility, configuring firewall rules for proper segmentation was not practical. The IoT devices ran specialized operating systems incompatible with standard agents.

How BTA delivered

BTA deployed Cisco Secure Workload to monitor and analyze network traffic, with ERSPAN collectors capturing unsampled flow data over a 4 to 5 week period. BTA then built deterministic permit-and-deny policies based on customer-defined manufacturing groupings and produced human-readable policy reports mapping to firewall rules.

Outcomes in production

Segmentation was successfully applied across dozens of applications and hundreds of IP devices, covering 20 separate manufacturing processes that represent the customer's complete steel production supply chains. Deployment completed without incident or downtime.

What makes us different

We're architects who execute.

Three principles every BTA engagement runs on. Visible in the work itself.

  • We architect, deploy, and stay through Day-2.

    Every engagement is end-to-end. We design the target environment, deploy it in stages, and remain on hand through the operational handoff.

  • We train your team to own the outcome.

    Training is part of every engagement. By the close of an engagement, your operators can run, maintain, and defend the system to an auditor.

  • We measure success when your team runs it alone.

    An engagement closes when your team is operating the solution without us in the room. SIMPLE methodology enforces this exit criterion on every project.
