Strengthen your cybersecurity posture with the very best tools. Our experienced technicians leverage advanced tools and a robust tech stack help you confidently stay ahead of evolving threats.

We use proven security testing methods—including vulnerability assessments, penetration testing, and configuration reviews—to identify gaps before they turn into incidents. For OT security and operational technology environments, we prioritize visibility and low-impact monitoring so critical systems stay stable and available. The result is a prioritized remediation roadmap that supports long-term cybersecurity risk management—not just a one-time checklist.

Support your business goals with a true partnership. We work with your internal teams to gain context, understand challenges, and tailor solutions for the best outcomes.

From day one, we align security recommendations to what matters most: uptime, compliance, and operational efficiency. Our approach supports smoother audits and risk assessments by documenting decisions, controls, and progress in a way stakeholders can actually use. Whether you're preparing for a cybersecurity audit or improving OT cyber security, we make security a shared plan—not an added burden.

Gain clear insights and knowlegeable advisory support. With years of hands-on expertise across critical sectors, iON serves as a true extension of your team with experts ready to help every step of the way.

We understand how security needs differ across IT and OT, and we help you balance protection with safety and performance requirements. Our team can guide incident response in cybersecurity, vendor risk planning, and ongoing OT risk management so you’re prepared before something goes wrong. We offer managed cybersecurity services that scale with your organization as your needs change.

OT security and IT security differ in both purpose and priorities. IT security is designed to protect data and focuses on confidentiality, integrity, and availability. OT security is focused on keeping physical processes running safely and reliably, with availability and safety taking precedence above all else.

OT environments often rely on legacy systems, specialized protocols, and equipment with long lifecycles that cannot be easily patched or taken offline, making traditional IT security approaches impractical or even dangerous. As IT and OT systems become more connected, effective security requires recognizing these differences and applying controls that protect operations without disrupting production or putting people at risk.

OT security solutions protect industrial environments without disrupting operations, safety, or uptime. At a high level, they focus on gaining visibility into OT assets, controlling access, limiting the spread of threats, and detecting abnormal behavior early. Effective strategies use methods that respect the constraints of legacy systems and industrial processes.

• Asset discovery and visibility tools that passively identify OT devices, communications, and critical dependencies.

• Network segmentation and zoning solutions that restrict lateral movement and isolate high-risk or high-value systems.

• Secure remote access tools that tightly control and monitor internal and third-party access to OT environments.

• Threat detection and monitoring platforms that recognize abnormal activity in industrial protocols and workflows.

• OT-focused risk and incident response solutions that prioritize safety, availability, and rapid recovery over traditional IT-centric controls.

OT infrastructure refers to the hardware, software, and networks used to monitor, control, and automate physical processes in industrial environments. Unlike IT infrastructure, which manages data and business applications, OT infrastructure directly interacts with machinery, equipment, and safety systems that keep operations running. It is commonly found in industries such as manufacturing, energy, utilities, and transportation, where uptime and safety are critical.

Examples of OT infrastructure include:

• Industrial control systems (ICS) such as SCADA, DCS, and PLCs

• Sensors and actuators that measure and control physical conditions

• Industrial networks and protocols like Modbus, DNP3, and OPC

Human-machine interfaces (HMIs) used by operators to manage processes

OT security protects the systems that keep operations running safely and reliably. When OT environments are compromised, the impact goes far beyond data loss—disruptions can halt production, damage equipment, create environmental or safety risks, and undermine trust in the organization.

OT systems are central to business continuity and revenue. For many companies, production infrastructure is the engine of the business, and even short outages can lead to significant financial loss and regulatory consequences. iON protects your OT infrastructure to ensure your critical operations remain resilient, controlled, and secure as connectivity and cyber risks continue to grow.

Having a dedicated OT security person or team is important because OT environments operate under very different constraints than traditional IT systems. Decisions that are routine in IT (such as patching, scanning, or taking systems offline) can disrupt production or create safety risks in OT. Someone with hands-on OT experience understands these realities, including legacy equipment, industrial protocols, and the need to prioritize availability and safety over rapid change.

OT support services can fill gaps that most organizations can’t staff internally. OT security requires continuous monitoring, specialized tooling, and experience responding to incidents that affect physical processes, not just networks. 

Partnering with an experienced OT security provider like iON gives organizations access to proven processes, industry-specific knowledge, and on-demand support. We help internal teams reduce risk, avoid costly mistakes, and maintain secure operations without slowing the business.
