Your manufacturing floor and industrial systems were built to run, not to be secured. As IT and OT networks converge, the attack surface grows — and standard IT security tools can damage the very systems they’re meant to protect. Fairway IT brings OT-aware security practices that keep your operations running and your industrial environment protected. From OT asset discovery to IT/OT network design, we address the full security lifecycle of your industrial environment. Manufacturing is the Most Ransomware-Targeted Sector for 3 Consecutive Years Passive, non-intrusive discovery of every device on your OT network — PLCs, HMIs, SCADA servers, sensors, and field devices — without disrupting production systems. Identify security gaps across your industrial control environment — unpatched firmware, default credentials, unnecessary remote access, and protocol vulnerabilities — with risk-ranked findings. of OT Environments Have Experienced a Security Incident in the Past Year Average Cost of an OT/ICS Security Incident Including Downtime Design and implement OT/IT network segmentation — firewalled DMZs, unidirectional data diodes, and Purdue Model-based zoning — to isolate critical control systems from corporate and internet traffic. Assess and improve your OT security posture against IEC 62443, NIST SP 800-82, and CMMC requirements — with a gap analysis report and prioritized remediation roadmap. of OT Devices Have Unpatched Critical Vulnerabilities We map your OT network using passive monitoring only — identifying every device, protocol, and communication path without sending a single packet to production systems. We assess identified assets against IEC 62443 and NIST 800-82, scoring vulnerabilities by exploitability and operational impact — so you know exactly what to fix first. We design and implement network segmentation, access controls, and monitoring solutions — staging all changes with your operations team to ensure zero production impact. We provide ongoing passive monitoring of your OT environment, proactive threat briefings, and regular posture reviews to stay ahead of new vulnerabilities and attack techniques. Operational technology (OT) refers to hardware and software that monitors or controls physical equipment, processes, and events — including industrial control systems (ICS), SCADA systems, programmable logic controllers (PLCs), and manufacturing execution systems. OT environments require specialized security because they were designed for availability and reliability, not security, and standard IT security tools can disrupt or damage industrial processes if applied incorrectly. IT/OT convergence is the integration of traditional enterprise IT networks (corporate systems, email, ERP) with operational technology networks (factory floor, control systems, sensors). While convergence improves efficiency and data visibility, it also exposes OT environments to threats from the IT network — including ransomware, phishing, and supply chain attacks. Managing the security boundary between IT and OT is critical to preventing attackers from reaching industrial systems. Yes — and the frequency and severity are increasing. Manufacturing is now one of the top targeted sectors for ransomware, and attacks on industrial systems can cause physical damage, production shutdowns, safety incidents, and regulatory violations. High-profile attacks on pipelines, food manufacturers, and utilities have demonstrated that OT environments are actively targeted. The risk is not theoretical. OT security must be approached differently than IT security. We start with passive network monitoring and asset discovery — so we can map the environment without touching any systems. Then we implement network segmentation to isolate OT from IT, deploy OT-aware security monitoring, and build incident response procedures that account for production continuity. Nothing is deployed on production systems without explicit testing and approval. Several frameworks apply depending on your industry. NIST SP 800-82 is the guide for ICS security. IEC 62443 is the international standard for industrial cybersecurity. CMMC/NIST 800-171 applies to defense contractors with OT environments. For manufacturers without a specific regulatory mandate, NIST CSF and IEC 62443 provide the strongest baseline for OT security programs. Fairway IT can assess your environment against whichever framework is most relevant to your business. Standard IT security isn’t enough for OT environments — and the wrong approach can do more damage than the threat it’s meant to prevent. Let’s start with a conversation about what you have, what’s exposed, and what a right-sized OT security program looks like for your operation. No long-term contracts required.
