IT/OT Assessments: Full OT Visibility, Reduced Risk, and a Practical Modernization Roadmap

Get a complete view of your OT environment, and a prioritized plan to improve uptime, strengthen cybersecurity, and modernize with confidence.

Let’s Talk

Why Manufacturers Choose an IT/OT Assessment

Most organizations struggle to align IT and OT teams because OT environments grow organically over time. The result is risk exposure, reliability challenges, and a lack of clear ownership. We see common issues including:

  • Limited visibility into OT assets and “what’s talking to what”
  • Cybersecurity blind spots in flat or underspecified OT networks
  • Unplanned downtime from communication failures or packet loss
  • Obsolescence across PLC/HMI/SCADA, servers, and networking gear
  • Inconsistent systems after acquisitions or site expansions
  • Misalignment between IT, OT, and operations teams

These pain points consistently appear across mid‑size and enterprise manufacturers in industries like Food & Beverage, CPG, Life Sciences, and Data Centers.

Bridging the Gap: The IT/OT Assessment Advantage

Core Drivers Shaping Client Demand

Across industries, organizations are facing escalating pressures that make a clear IT/OT strategy essential.

Cyber risk and insurance pressure for asset visibility and segmentation

Upcoming modernization needs across controls and networks

Multi‑site standardization initiatives

Uptime, throughput, and OEE improvement targets tied to reliability

Pressure to reduce unplanned downtime and improve visibility

Leadership demand for clear, defensible investment plans

What You Get: Decision- Ready Deliverables

A detailed, system-wide list of all operational technology assets, including hardware specifications, firmware and software versions, lifecycle and end‑of‑life status, and configuration information. The inventory also includes health indicators such as device errors, communication quality, resource utilization, and any abnormal behaviors. The goal is to create a reliable baseline that supports risk assessment, lifecycle planning, and modernization decisions.

Comprehensive physical and logical maps that show how all devices, controllers, and systems connect within the production environment. This includes identification of unmanaged switches, undocumented connections, segmented networks, and isolated equipment. Communication pathways are reviewed to identify bottlenecks, overloaded links, redundant paths that are not functioning properly, and single points of failure that could cause downtime or instability.

A focused evaluation of cybersecurity exposures unique to OT environments. This includes insecure protocols, insufficient segmentation, weak authentication practices, and outdated or unpatched systems. Access control structures, identity management, and boundary protections are examined for gaps. All findings are aligned to widely recognized frameworks such as NIST and ISA/IEC 62443 so that remediation efforts follow established best practices.

An analysis of the core issues that affect operational reliability and production stability. This includes identification of root causes behind unplanned downtime, intermittent network failures, latency in control communications, and device performance problems. Environmental contributors, misconfigurations, aging components, and poorly maintained assets are also assessed to determine their impact on daily operations.

A structured and actionable plan that highlights the most important steps for improving security, stability, and performance. Items are grouped into quick wins, short‑term actions, and long‑term strategic initiatives. Each recommendation includes estimated effort, expected benefits, and priority level to support budgeting, planning, and alignment with operational goals.

A forward-looking roadmap that outlines the recommended architecture direction, phased modernization activities, and potential timelines. The roadmap includes guidance on replacing legacy systems, adopting more scalable architectures, integrating data more effectively, and strengthening cybersecurity maturity. High-level budget considerations help guide long-term investment decisions.

A clear and accessible summary that communicates the technical findings in a business-focused manner. This section quantifies operational and cybersecurity risks, highlights the most critical issues, and explains the potential business impact. The summary enables leaders and stakeholders to quickly understand the situation, prioritize decisions, and support modernization and remediation efforts.

How the Assessment Works

We keep production impact low and coordination tight across IT, OT, and operations.

Designed Around Production: We use low‑impact methods and coordinate with operations and maintenance teams to avoid or minimize downtime.

Outcomes and Impact

  • Stronger Cyber Posture
    • Gain clarity on vulnerabilities and reduce attack surface with segmentation, micro‑segmentation, layered network defense zones, and monitored access controls.
  • Improved Uptime & Reliability
    • Identify and resolve root causes of instability, misconfigured devices, communication losses, and aging infrastructure that adds risk and reduces efficiency.
  • Insurance & Audit Readiness
    • Receive documentation aligned to NIST and ISA/IEC standards, supporting cyber insurance renewals and auditor expectations.
  • Real‑World Resilience Example
    • A food & beverage facility maintained full production during a cyberattack because previous assessment‑driven segmentation (including a DMZ) prevented OT compromise.

Who Does the Assessment Help?

  • IT & Security Teams
    • Eliminate OT blind spots, enforce segmentation, and support compliance and insurance requirements.
  • Plant & Operations Leaders
    • Stabilize production, improve uptime, and get clarity on where and how to invest.
  • Controls & Automation Engineers
    • Identify risks across mixed‑vintage PLC, HMI, and SCADA systems and plan modernization.
  • Maintenance & Reliability Teams
    • Receive practical, prioritized fixes and documentation that simplifies long‑term support.
  • Executives (CIO/CTO/COO)
    • Align operations, cybersecurity, and modernization through a clear, data‑backed roadmap that provides predictable costs and reduced risk.
