Secure Development and Application Security

Specialised System and Device Testing

Assurance for complex systems beyond standard testing

Modern products are no longer “just software”. They are devices, radios, protocols, firmware, cloud backends and industrial environments stitched together. In these systems, standard scanning and generic penetration testing often miss what matters most: protocol abuse, firmware flaws, insecure update chains, exposed debug paths and the weak assumptions that adversaries exploit in the real world.

Specialised System and Device Testing gives you deep, tailored assurance before deployment, acquisition or large-scale rollout.

Designed for organisations building or operating complex systems where standard testing approaches fall short — including IoT, industrial, wireless or telco devices.

Specialised Testing, defined

A bespoke security assessment approach designed for systems where off-the-shelf tools and standard methods are insufficient.

Specialised testing combines expert-led analysis with tailored attack development, grounded in established security principles and sector-specific standards. It identifies weaknesses across device firmware, protocols, interfaces and architectures and translates them into clear, actionable remediation guidance.

All specialised testing engagements follow the same principle: understand the system’s critical assumptions, test the attack surfaces that matter most and validate fixes before deployment.

When Specialised Testing supports your goals

Assess critical technologies before they reach production environments, customers or national infrastructure.

Focus testing on the attack surfaces adversaries are most likely to use: update chains, debug access, wireless protocols and local services.

Apply specialised methods for industrial systems, operational technology and telecommunications, where safety, uptime and resilience are as important as confidentiality.

How it works

  • Scope what “critical” means

    Define the system boundaries, threat scenarios and impact. Identify the components and interfaces that must hold under pressure.

  • Select the right access mode

    Choose the fastest path to impact based on your stage and constraints: black-box realism, grey-box depth under tight timelines or white-box coverage with full artefacts.

  • Test the real attack surfaces

    Investigate the areas where complex systems fail in practice: boot and update trust, exposed debug interfaces, protocol misuse, wireless onboarding, local APIs, device identity and cloud linkage.

  • Strengthen and retest

    Deliver prioritised remediation and verify fixes, including regression-proof guidance so fixes remain effective as systems evolve.

Our core capabilities

Custom tests for non-standard systems

Bespoke assessments designed for systems that require a one-of-a-kind approach. Typical targets include SCADA and industrial environments, mobile payment implementations such as HCE, IoT devices, digital meters, kiosks, payment gateways and wireless systems using Zigbee or Z-Wave.

Device and firmware security testing

Full-stack testing for devices that ship firmware and connect to the world, from consumer IoT and routers to mobility and regulated environments. We focus on the surfaces that drive real compromise at scale: boot and update chains, secrets and storage, radio and proximity, debug and test interfaces, local services and APIs, sensors and actuators and the cloud, mobile and identity layer.

Industrial and OT security assessments

Specialised expertise for operational technology and industrial control environments, where safety and process uptime define risk. This includes OT network architecture, segmentation strategies, protocol and boundary assurance and resilience planning aligned with critical infrastructure realities.

Telecommunications and Mobile Network Security

Deep technical testing for telco infrastructure and mobile networks, covering the ecosystem across interconnect, RAN and core. We assess exposure, configuration hardening, protocol risks and structural gaps — then help prioritise mitigations that close real-world attack paths.

The results that matter

  • Clear understanding of the weakest links in complex systems
  • Issues uncovered beyond standard scanning and generic testing
  • Practical remediation guidance for firmware, protocols and architectures
  • Reduced exposure across the interfaces attackers target most
  • Confidence to deploy, scale or integrate systems securely
