IoT & Embedded Device Penetration Testing

Expert-led, manual security testing for connected devices, from consumer IoT to industrial embedded systems.

Connected devices expand your attack surface in ways that traditional penetration testing doesn’t cover. Firmware vulnerabilities, insecure hardware interfaces, weak cryptographic implementations, and unprotected network protocols all represent real attack paths, and most automated tools can’t touch them. Our CREST-accredited consultants bring hands-on hardware and firmware expertise to every IoT and embedded device engagement, testing the full system the way a real attacker would.

Service Overview

IoT & Embedded Device Penetration Testing

An IoT and embedded device penetration test is a structured, expert-led security assessment of a connected device and its surrounding ecosystem, covering the device hardware, firmware, companion applications, network communications, and back-end cloud or server infrastructure. Unlike web or infrastructure testing, embedded device assessments require physical access to hardware, specialist tooling for firmware extraction and analysis, and consultants with experience in low-level systems and embedded architectures.

The consequences of a compromised IoT device extend beyond data theft. Where devices have access to critical infrastructure, operational technology networks, or physical systems, the impact of a successful attack can be severe. For consumer devices handling personal data, the regulatory implications of poor security design are increasingly significant.

Our Test Process

Our IoT Testing Process

Every IoT / Embedded device penetration test goes through a rigorous process to ensure you get the best possible results. Below we outline the key stages our testing goes through:

Understand Your Requirements

IoT engagements require more upfront scoping than other service types. We work with you to understand the device architecture, the ecosystem it operates within, the interfaces it exposes, and what a successful assessment looks like, before agreeing scope and timeline.

Manual, Expert-Led Testing

Every assessment is carried out by consultants with hands-on expertise. We use specialist tooling to support our work, but every finding is the result of manual investigation, not automated output. This means validated vulnerabilities and accurate impact assessment.

Reporting Tailored To Your Organisation

Our reports are written for those who need to act on them, whether that's an engineering team working on pre-release or a security team managing deployed devices in a corporate environment. Technical findings include full exploitation detail & clear remediation guidance.

Post-Test Remediation Support

Our consultants don't disappear when the report is delivered. They remain available to answer any questions you may have and assist with remediation prioritisation. Where compliance evidence is required, we can provide additional documentation to support audit requirements.
