OT, ICS, and IoT Security: Protecting connected operations
Operational Technology (OT) includes the systems that control physical processes—like SCADA, DCS, and PLCs—used in industries such as manufacturing, energy, and transport.
The Internet of Things (IoT) connects devices, sensors, and systems, while the Industrial IoT (IIoT) applies this to industrial settings, overlapping with OT.
As IT and OT converge, connectivity grows—but so does risk. This integration expands the attack surface, making OT/ICS and IoT security essential for protecting operations and safety

Why Specialised OT, ICS, and IoT Security is Essential
Industrial and IoT environments face threats that standard IT security tools simply weren’t built for. Most OT systems were designed decades ago with no security in mind — and connecting them to the internet has exposed that gap.
Ensuring Safety
Protecting against cyberattacks that could cause physical harm to personnel, disrupt essential services, or damage the environment.
Maintaining Uptime
Preventing disruptions to critical industrial processes and essential IoT services, which can lead to significant financial losses and reputational damage.
Regulatory Compliance
Adhering to industry-specific regulations and standards (e.g., NERC CIP, IEC 62443, NIST framework, and various IoT security guidelines).
Safeguarding Infrastructure
Protecting essential services society relies on, such as power grids, water treatment plants, smart city infrastructure, and transportation networks.
Protecting IP & Data
Securing sensitive operational data, proprietary industrial processes, and the vast amounts of data generated and transmitted by IoT devices.
Securing Attack Surface
Addressing the security of a rapidly expanding number of connected devices, many of which may have inherent vulnerabilities.
The Unique Challenges of Securing OT, ICS, and IoT Environments
Legacy Systems & Device Lifecycles
Legacy OT systems were built for reliability, not security. Many run outdated firmware with no patch support, long replacement cycles, and no visibility into who is accessing them.
Connectivity Risks & Expanded Attack Surface
The increasing integration of OT with IT networks and the internet, coupled with the sheer volume of IoT devices, dramatically expands the attack surface, exposing previously isolated systems to external and internal threats.
Proprietary & Diverse Protocols
OT networks often use specialised, sometimes unencrypted, communication protocols. IoT ecosystems involve a wide array of communication standards, many of which may have security weaknesses. Standard IT security tools may not understand or adequately protect these diverse protocols.
Operational Impact & Resilience
Security measures must be implemented without compromising the availability, reliability, or safety of industrial processes and essential IoT services. Downtime is often unacceptable
Targeted & Opportunistic Attacks
Critical infrastructure, industrial operations, and large-scale IoT deployments are increasingly attractive targets for sophisticated cyber adversaries, including state-sponsored actors, cybercriminals, and hacktivists.
Skill Gap & Asset Visibility
There is a recognised shortage of professionals who possess deep expertise in OT engineering, IoT technologies, and cybersecurity. Many organisations lack a complete inventory of their OT and IoT assets, making it difficult to identify, manage, and protect them effectively.
