Maintenance for the company’s diverse, interconnected production lines was both costly and time-consuming, requiring constant on-site maintenance visits. Determined to reduce expenses without compromising security or performance, they sought a remote maintenance solution. Several IT providers claimed that a secure and efficient remote maintenance solution simply wasn’t possible.

Under a dedicated OT security mandate, CLUE executed a three-pronged approach:

• Centralized, granular access
  CLUE created a secure remote-access environment that requires internal approval for every connection via a strict “four-eyes” principle—ensuring no external provider can initiate a session independently.

• Efficient microsegmentation
  By segmenting the network into security zones aligned with IEC 62443 and the Purdue Model, the company now strictly regulates who accesses which systems, and for how long.

• Streamlined rollout & management
  Standardized templates and automated provisioning enabled a smooth deployment of secure gateways across all facilities, minimizing reliance on core IT teams and speeding up maintenance.

• Significant cost reduction
  Eliminating 800+ annual engineering trips saved time and significant travel costs.

• Boosted security & compliance
  Production lines are now protected by a robust, centralized framework that meets strict corporate and industry standards.

• Greater transparency & control
  All remote sessions are monitored and tightly regulated, giving the company complete visibility into every access request.
