Securing connected device fleets from silicon to cloud.
A connected device is never just a device — it is firmware, a provisioning process, a communication path, a cloud back-end and an update mechanism, each with its own failure mode. We assess and secure the whole chain, with particular depth where those devices sit in industrial environments.
- Device → cloud

Platform and API security
Frameworks we work to.
IoT security guidance is fragmented across sectors and regions. We work out which baselines apply to your market, then assess against one consolidated control set.
Component security requirements
Where the device is destined for an industrial environment, the technical capabilities it must demonstrate to be usable at a given security level.
How we support you
- Component capability assessment by foundational requirement
- Security level capability determination
- Hardware and firmware requirement allocation
- Secure boot and root of trust review
- Integrator security guidelines
- Gap remediation plan
Consumer and industrial IoT baseline requirements
Regional baseline expectations — no universal default passwords, disclosed vulnerability handling, update support periods and secure communications — that increasingly gate market access.
How we support you
- Applicable baseline identification by market
- Baseline gap assessment
- Credential and provisioning redesign
- Vulnerability disclosure policy and process
- Support lifetime and update commitment definition
- Declaration of conformity support
Provisioning, update and decommissioning
The operational reality of a fleet: how identity is issued, how updates are signed and delivered, how a compromised device is contained and how it is retired.
How we support you
- Identity and certificate lifecycle design
- Zero-touch provisioning security review
- Signed update and rollback mechanism assessment
- Fleet segmentation and containment approach
- Key management and secure element usage
- Decommissioning and data sanitisation process
Platform and API security
The other half of the system — device gateways, telemetry ingestion, command paths and the APIs that let an attacker reach thousands of devices at once.
How we support you
- Device-to-cloud authentication review
- Command and control path assessment
- API authorisation and tenancy isolation testing
- Telemetry integrity and data handling review
- Back-end monitoring and detection coverage
- Blast-radius analysis for platform compromise
What an IoT engagement covers.
The same seven services run across every practice, so you can compare scope without re-learning the menu.
Risk assessment
Threat modelling across the full chain — device, communications, back-end and the physical consequence of mass compromise.
Advisory & consulting
Product security strategy, baseline selection for target markets, and architecture review of provisioning and update design.
VA-PT & security testing
Firmware analysis, hardware interface review, communication and API testing — on samples and lab fleets, never on live critical deployments.
Compliance & audit readiness
Readiness against applicable IoT baselines and, for industrial devices, IEC 62443-4-2 capability requirements.
Implementation support
Secure boot, key and certificate management, provisioning redesign, update pipeline hardening and fleet segmentation.
Security operations
Fleet monitoring, anomaly detection across device telemetry, and incident containment for devices you cannot physically reach.
Training & capability
Embedded and platform security training for firmware, cloud and product teams.
