# IoT & OT Cybersecurity

Tailored consulting that secures your ecosystem of connected devices, networks and industrial systems, from sensors to SCADA.

## What’s included

### IoT & OT cybersecurity strategy

A cybersecurity strategy built specifically for IoT and OT environments, covering connected devices, networks and industrial control systems.

### Regulatory compliance for IoT/OT

- Compliance with standards such as NIST SP 800-82, ISA/IEC 62443 and GDPR.
- Compliance frameworks aligned with national and international best practice.

### IoT & OT vulnerability scanning

- Continuous scanning of connected devices and OT systems, including control systems, sensors and actuators.
- Unpatched devices, insecure channels and misconfigurations found before they lead to breaches.

### Wireless & network security testing

- Testing of wireless networks common in IoT, such as Wi-Fi, Zigbee and LoRaWAN.
- Review of protocols and configurations across interconnected industrial networks.

### Risk assessment for IoT/OT

- In-depth assessments of devices, sensors, networks and OT systems such as SCADA and PLCs.
- Threats like unauthorised access, data breaches and malware identified across IoT and OT.

### IoT/OT incident response

- Response plans designed for IoT and OT environments.
- Rapid recovery and forensics for OT incidents, including attacks on critical infrastructure.

### Penetration testing for IoT/OT

- Ethical hacking of firmware, communication protocols and access controls.
- Assessment of physical and network attack paths to SCADA, PLCs and embedded systems.

### IoT/OT device security review

- Hardware and firmware analysis of individual devices.
- Review of device authentication, encryption and data protection.

Standards and technologies

- ISA/IEC 62443
- GDPR
- SCADA
- PLC
- Wi-Fi
- Zigbee
- LoRaWAN

## Why OT needs a different approach

Industrial systems control physical processes, so an attack can stop production, damage equipment or put lives at risk. The Gulf has seen this first hand: Shamoon hit regional energy companies, and Triton was built to attack the safety systems of an industrial plant in the Kingdom.

|  | IT security | OT security |
| --- | --- | --- |
| Top priority | Confidentiality of data | Safety and availability |
| System lifespan | 3 to 5 years | 15 to 30 years |
| Patching | Regular and fast | Rare, during planned shutdowns |
| Protocols | Standard internet protocols | Modbus, DNP3, Profinet, OPC UA |
| Testing | Active scanning is normal | Active scanning can crash devices |

## The Purdue model and segmentation

Most OT programmes use the Purdue model to separate field devices (levels 0 and 1), control and supervisory systems (levels 2 and 3) and the business network (levels 4 and 5). A well-designed industrial DMZ between IT and OT is one of the most important protections. We combine Purdue with IEC 62443 zones and conduits to design segmentation that holds.

## Our safe approach

We never run aggressive scans on live control systems. We prefer passive monitoring, work in planned maintenance windows, coordinate with operations and safety teams, and test in a lab or staging environment wherever possible.

## Why CYBRT

### Riyadh-based, Gulf-focused

Headquartered in Riyadh, working with organisations across Saudi Arabia and the Gulf.

### Certified consultants

Our team holds CISA, CISM, CRISC, CGEIT, CDPSE, CCSP, CCSK, COBIT and ISO 27001 Lead Auditor certifications, among others.

### Regulation-ready

We work with NCA and SAMA frameworks alongside ISO, NIST and PCI-DSS, so controls map straight to what auditors expect.

### End to end

Six connected services, from strategy and awareness through testing, operations, cloud and technology.

## Frequently asked questions

### Which OT security standards do you work with?

NIST SP 800-82 and ISA/IEC 62443 for industrial systems, plus GDPR where personal data is involved. We build compliance frameworks that align with national and international best practice.

### Can you test SCADA systems and PLCs?

Yes. Our IoT/OT penetration testing and risk assessments cover SCADA, PLCs and embedded systems, including firmware, protocols, access controls and physical attack paths.

### Which wireless protocols do you test?

Wi-Fi, Zigbee and LoRaWAN, along with the network protocols and configurations that connect industrial devices.

### Who must comply with NCA OTCC?

Organisations covered by ECC that own, operate or use OT systems, particularly in critical national infrastructure sectors.

### Is our OT network safe if it is air-gapped?

True air gaps are rare. Remote access, USB drives, engineering laptops and undocumented links often connect OT to the outside world.

### What is the difference between IoT and OT?

OT controls industrial physical processes. IoT covers connected devices more broadly, from sensors to cameras. Industrial IoT sits where the two meet.
