IoT/OT Security Assessment
Before an attacker does
IoT/OT Security Assessment (ISA)
Penetration testing, security auditing and reverse engineering for IoT devices, connected machines and OT environments.
ISA - IoT/OT Security Assessment verifies the security of IoT devices, firmware, hardware, software, APIs, industrial protocols, OT networks and remote access using an attacker-led approach.
From machine to cloud, ISGroup identifies real vulnerabilities before they can be exploited and produces technical evidence for audit, compliance, certification, supplier qualification and risk management processes required by CRA, Machinery Regulation, RED Delegated Act, NIS2 and IEC 62443.
Before an attacker does, find out whether your connected machines, IoT devices or OT environment can be compromised.
Offensive approach
We assess products, firmware, software and IoT/OT architectures as a real attacker would.
Technical evidence
We produce results that can be used in audits, compliance, certifications and supplier qualification.
End-to-end coverage
We test from machine to cloud: hardware, firmware, APIs, protocols, OT networks and remote access.
Regulations require security to be demonstrated. We put it to the test.
European regulations are making it mandatory to demonstrate what was often implicit before: that devices, software, firmware, remote access and industrial architectures are designed and verified against real cyber risks.
To demonstrate that a connected machine, IoT device or OT environment is secure, you first need to test it as an attacker would.
ISA combines penetration testing, vulnerability assessment, security auditing and reverse engineering to verify the security of IoT devices, connected machines, software/hardware components and OT environments.
What we do and what we do not do
ISGroup does not replace certification bodies, legal consultants or notified bodies. We do not sell certified hardware, CE marking or regulatory consulting.
We work where deep technical expertise is required: penetration testing, security assessment, firmware analysis, reverse engineering, hardware/software testing, protocol testing, vulnerability assessment, source code review, forensic analysis and offensive validation.
The ISA service supports companies, OEMs, system integrators and industrial users in producing technical security evidence that can be integrated into compliance, audit, certification or supplier qualification processes.
Connected machines and OT environments
For OEMs, machine builders, manufacturing and system integrators.
Every new connection between a machine, OT network, cloud, dashboard, gateway or remote access channel can introduce unexpected attack surfaces. ISA verifies these risks with controlled offensive methodologies suitable even for critical industrial environments.
Relevant regulatory drivers: Machinery Regulation 2023/1230, IEC 62443 and NIS2 Directive.
- IT/OT networks and segmentation
- ICS, SCADA, DCS systems
- PLC and HMI
- Remote access and remote machine maintenance
- Telemetry and industrial cloud integrations
Substantial modification
Connections, remote access and integrations can introduce cyber and safety risks that must be documented before they become operational, contractual or regulatory exposure.
The Machinery Regulation defines a substantial modification as a physical or digital modification not foreseen by the manufacturer that affects machine safety by creating a new hazard or increasing an existing risk.
When a digital modification, remote access or IoT/OT integration affects the safety, behavior or control of a machine, it becomes essential to document and technically verify the risk introduced.
Industrial IoT, edge gateways and telemetry
For teams that develop or integrate gateways, sensors, edge systems, dashboards and predictive maintenance.
We verify the security of the entire data chain, from sensor to cloud: edge gateways, telemetry, remote access, industrial APIs, cloud backends and MQTT, Modbus, OPC UA protocols.
Relevant regulatory drivers: Cyber Resilience Act, RED Delegated Act, EN 18031 and IEC 62443.
IoT devices and products with digital elements
For companies that develop or market connected products.
The Cyber Resilience Act introduces cybersecurity requirements for products with digital elements across the entire design, development, production and vulnerability management lifecycle.
- IoT penetration testing
- Hardware penetration testing
- Firmware analysis and reverse engineering
- API, mobile app and backend security testing
Software, firmware, source code and reverse engineering
This is where ISGroup's technical depth makes the difference. We analyze firmware, binaries, source code, protocols, APIs, mobile applications, backends and hardware components to identify exploitable vulnerabilities in real-world scenarios.
- Source code review and secure coding review
- Firmware security assessment and firmware analysis
- Reverse engineering and binary analysis
- Embedded security and hardware/software testing
What we test
During an IoT/OT Security Assessment, ISGroup verifies, among other things:
- Secure communications and channel encryption
- Memory corruption and low-level errors
- Local and remote management interfaces
- Platform protection, storage and data persistence
- Cryptographic analysis and update mechanisms
- Authentication, authorization and access control
- Backends, infrastructure and mobile integration
- MQTT, Modbus, OPC UA, Profinet, BACnet, CAN bus, LoRaWAN, Zigbee, Z-Wave, Wi-Fi and Bluetooth protocols
This list is only a partial view: every assessment is shaped around the product's or environment's real attack surface.

Technical evidence for your regulatory processes
ISA produces technical evidence that can be used in audit, qualification, certification and risk management processes connected to CRA, Machinery Regulation, IEC 62443, NIS2, RED Delegated Act and EN 18031.
| Regulation | Who needs it | How ISA contributes |
|---|---|---|
| Cyber Resilience Act (CRA) | Organizations that develop or market products with digital elements | Penetration testing, firmware analysis, technical vulnerability management |
| Machinery Regulation 2023/1230 | OEMs and users of connected machines | Verification of cyber/safety risk introduced by connections and substantial modifications |
