Inspired Network Solution for Safe & Reliable Operations

We design safe, reliable and secure network solutions.  We are experts in Operational Technology (OT) and Information Technology (IT) and we speak the language of both the Factory Floor and Corporate IT. By taking each group’s priorities and objectives into consideration, we bridge the OT/IT gap.  

A 3-step process to make your Operational Technology (OT) network and systems safe:

Step 1: OT / Cyber Audit

A complete audit of all OT equipment and security is the first step to assess the current system. An audit includes survey, report and recommendations on:

  • Ethernet network device review
  • Non-ethernet networks and bridging review
  • Inventory of all OT equipment including:
    • PLCs, HMIs and Smart devices (models, features, firmware versions)
    • Servers/PCs (OS and applications)
  • Environmental controls assessment
  • Patch Management
  • Cybersecurity Evaluation
  • Backup and Disaster Recovery process review

Step 2: Remediation

Based upon the results of the OT / Cyber Audit, we will guide you through the next steps to improve the security of your network, systems and processes. We will design the OT network solution specific to your facility by analyzing the tradeoffs of cost, administrative overhead and security risk.

  • Virtualization
  • Thin client solutions
  • Switch/router configuration

Step 3: On-Going Monitoring & Support

Our team of OT and IT professionals can assist with keeping your systems running and respond to threats if needed.  We focus on achieving your goals for up-time, optimizing performance and managing recovery.
