IoT & IIoT Security

As organisations increasingly adopt Internet of Things (IoT) and Industrial Internet of Things (IIoT) technologies to optimise operations, they also open the door to new and complex cyber threats. At [Your Organisation Name], we help our clients protect their connected environments—ranging from industrial control systems to smart building technologies—through robust and adaptive security measures.

Securing IoT and IIoT isn’t just about firewalls and passwords. It requires an ecosystem-wide approach, built on visibility, control, and resilience. Our process is grounded in well-defined stages and flows that support long-term governance and compliance.

Our IoT/IIoT Cybersecurity Approach

We start by mapping the entire digital footprint of your OT/IoT infrastructure. This helps us identify vulnerabilities, define access policies, and build a zero-trust architecture tailored to your business. Each of the following components plays a crucial role in our approach:

Access Control & Identity Management (IAM for OT/IoT)

We enforce role-based and device-specific access controls across your IoT environment. IAM ensures only authorised personnel and devices can access sensitive functions. We integrate with your existing identity providers and extend policies to legacy OT systems where possible.

Asset Discovery and Management

You can’t protect what you can’t see. We implement automated discovery tools to continuously inventory all IoT and IIoT devices. These assets are categorised, tagged, and monitored—helping identify anomalies and shadow IT.

Compliance & Governance

From GDPR and NIS2 to sector-specific regulations, compliance frameworks are deeply embedded into our process. We work with your risk and compliance officers to align technical controls with regulatory requirements. Our governance model defines clear roles, responsibilities, and escalation paths.

Network Detection & Response (NDR)

Real-time threat detection is critical. We deploy NDR systems that leverage behavioural analytics and machine learning to detect anomalies on your network. Our platform isolates threats quickly and provides incident timelines for forensic analysis.

Privileged Access Management (PAM)

IoT and IIoT systems often require elevated privileges for maintenance or configuration. PAM helps ensure that high-level access is limited, monitored, and logged. We also deploy just-in-time access mechanisms for critical updates.

Vulnerability Management & Risk Assessment

We perform ongoing vulnerability scanning and threat modelling across all assets. Each finding is risk-rated based on the potential impact and likelihood, allowing us to prioritise remediation efforts. Our assessment includes:

• Regular scanning and patching schedules

• Supply chain vulnerability checks

• Context-aware risk scoring

Secure Remote Access (e.g. ZTNA)

Zero Trust Network Access (ZTNA) replaces traditional VPNs with access models that verify each session, device, and user individually. This is vital for external vendors or engineers accessing OT environments remotely. ZTNA ensures encrypted, least-privilege access by default.

Network Segmentation & Microsegmentation

We design your network to isolate critical systems from less sensitive environments, preventing lateral movement in case of a breach. Microsegmentation enables policy enforcement at the workload level, further reducing the attack surface.

Our Process Flow

To ensure a structured implementation, we follow this security lifecycle:

1. Assessment & Inventory – Identify assets and risks

2. Policy Definition – IAM, PAM, segmentation rules

3. Implementation – Deploy tools and enforce controls

4. Monitoring & Response – Real-time detection and alerting

5. Review & Optimisation – Continuous improvement and governance alignment

Let’s Make IoT & IIoT Secure by Design

Securing your connected infrastructure is no longer optional—it’s essential for operational resilience, regulatory compliance, and long-term innovation. Whether you’re deploying new IoT sensors or modernising legacy OT systems, we can help you secure them from the ground up.
