Bring enterprise-grade security to operational technology
The stakes rise as industrial control systems converge with enterprise IT. Secure OT environments end to end, protecting uptime, safety and trade secrets across people, process and technology.
What is Operational Technology (OT) security?
Managing risks across IT and OT security environments
As industrial control systems (ICS) converge with enterprise networks and traditional IT environments, WWT's operational technology (OT) security solutions and services help ensure the safety and integrity of industrial operations including IoT assets that help control and monitor these environments.
Key challenges for OT / IT convergence
Blind spots
IT and OT teams monitoring different tools with little overlap, plus gaps attackers exploit before defenders notice.
Legacy systems
Thousands of undiscovered endpoints, and PLCs, SCADA and HMIs that cannot be patched without halting production.
Compliance
Multiplying frameworks, plus vendor and remote-support access paths that are rarely monitored.
Why you need to build an OT security program
OT breaches stop production
Ransomware targeting OT environments has increased by 49% year over year. They can take production lines offline for weeks. Every hour of unplanned downtime has a direct financial and reputational cost.
OT security meets the business need of operational continuity.
Your IT tools were not built for the plant floor
Standard EDR, SIEM, and vulnerability scanners can disrupt or crash industrial equipment. OT security requires purpose-built, passive, protocol-aware approaches.
OT security respects the constraints of industrial environments.
Compliance is the floor
Meeting compliance requirements means you're auditable, not necessarily secure. OT security includes continuous risk management, threat hunting, and adaptive control improvement.
Mature OT programs go beyond checkbox compliance.
Bad actors are already in critical infrastructure
Volt Typhoon, Sandworm, and other advanced persistent threat groups have demonstrated persistent access to energy, water, and manufacturing systems. The threat is present, patient, and targeted.
OT security defends against real world harm.

Our approach to a complete OT security framework
A security program built for operational reality
Our OT Security framework is designed around six clear outcomes, each tied to measurable risk reduction and operational continuity. These objectives form a complete program, not a checklist.
What we do
Discover, classify, and inventory every OT/ICS asset (from PLCs to sensors) across all sites, including air-gapped and remote environments. Build the foundation every security control depends on.
Segment OT from IT, close unused ports and remote-access paths, and remove default credentials. Every entry point closed is one less way in.
Deploy OT-native monitoring and anomaly detection that understands industrial protocols and identifies threats without generating operational false positives that disrupt production.
Build OT-specific playbooks and tabletop exercises so your team can contain and recover from incidents quickly, without halting production unnecessarily or extending downtime.
Map controls to NERC CIP, IEC 62443, NIST CSF 2.0, and sector-specific requirements, with continuous monitoring to sustain posture between audits and regulatory reviews.
Break down silos with a shared risk framework, joint SOC capabilities, and executive reporting that communicates risk in both operational and financial terms your board can act on.
How we do it
Assess
Rapid Visibility Assessment and Advanced Assessment. Current-state analysis and gap analysis.
Architect
Segmentation and high- and low-level design, proven in WISE before deployment.
Implement and sustain
Deployment, program development, governance, and OT-specific incident response playbooks.

Industries
OT security looks different in every industry
A water plant and a pharmaceutical line face the same attackers and almost none of the same constraints. We start with how your operation actually runs, then secure it without shutting it down.
Manufacturing
Protect production lines from ransomware without halting the factory floor.
Energy
Defend generation and pipeline controls from nation-state attacks.
Life Sciences
Safeguard validated production systems while maintaining compliance.
Utilities
Meet NERC CIP mandates while modernizing grid and water controls.
Healthcare
Secure medical devices and facility systems for patient care.
WWT Industry Solution Experience (WISE)
WWT's Demonstration lab for industrial IT/OT collaboration
OT security is successful when you can prove what works in complex industrial environments. WWT's WISE provides a safe place to test segmentation, validate controls, and assess how IT and OT systems respond to real-world threats without disrupting operations.

Frequently Asked Questions
Explore common questions about OT security, IoT security, and why industrial environments need to invest.
OT security solutions protect the industrial control systems (ICS), SCADA environments and connected IoT assets that run physical operations. These services include risk assessments, network segmentation, asset visibility and continuous monitoring, delivered end-to-end by WWT. We evaluate control maturity across IT and OT environments, then design and deploy protections validated in the Advanced Technology Center and WWT Industry Solution Experience (WISE) lab, a demonstration environment built specifically for industrial IT/OT collaboration.
OT security means protecting operational technology such as ICS, SCADA and PLC systems that control physical processes in plants, grids and pipelines. IoT security means protecting connected sensors and devices that monitor those environments. The two converge in practice, and WWT's OT security solutions and services address both.
IT/OT convergence removes the air gap that once protected industrial systems: when plant networks connect to enterprise IT and cloud services, legacy PLCs and SCADA systems become reachable by phishing and ransomware, the two most-reported OT intrusion vectors (76% and 50% respectively, per Fortinet's 2025 State of OT report), the same campaigns that target corporate IT. WWT bridges the gap with unified IT/OT risk assessment and segmentation strategies, like the micro-segmentation program it piloted across a manufacturer's 2,500 applications.
Manufacturing, energy, utilities and life sciences see the highest OT security impact. Manufacturing alone accounted for more than two-thirds of industrial ransomware victims in 2025, according to Dragos. These critical infrastructure sectors face regulatory pressure (NERC CIP, IEC 62443) and safety exposure. WWT has delivered OT security programs across each one.
OT security investment pays back through avoided downtime and breach cost. The average industrial-sector data breach costs $5.0 million (IBM, 2025), before counting production outages. Maturity works. 65% of organizations at the highest OT security maturity level reported zero intrusions in the past year, versus 46% at the lowest levels (Fortinet, 2025). WWT structures programs to capture that curve, starting with an OT risk assessment that benchmarks control maturity across IT and OT environments before any tooling spend.
