Device Security
Security testing from the chip to the cloud
Connected devices ship with firmware, wireless stacks, APIs, and cloud backends - every layer is an attack surface. We test the entire device ecosystem, from the hardware up through the supporting infrastructure, to find vulnerabilities before they reach the field.
What we test
The full device stack
Our IoT and device security assessments cover the hardware, firmware, communications, APIs, and cloud infrastructure that make up modern connected products.
Firmware Analysis
We analyze firmware images for hardcoded secrets, insecure update mechanisms, and integrity-breaking conditions. We also evaluate the security of the firmware update process itself - from delivery to installation.
Hardware Security
Physical device testing including debug interface exposure, JTAG and UART access, chip-level analysis, and tamper resistance. We assess whether an attacker with physical access can extract secrets or modify device behavior.
Wireless and Protocol Testing
We evaluate wireless stacks including Wi-Fi, Bluetooth, Zigbee, cellular, and proprietary protocols. We build test infrastructure in-house to thoroughly assess wireless security - including protocol gateways and base stations.
Device API and Interface Security
Whether unidirectional or bidirectional, the APIs on both the device and its supporting services present security risks. We evaluate end-to-end communications between nodes and services for authentication, authorization, and data integrity.
Embedded Systems
Security assessments for RTOS environments, bare-metal applications, and constrained devices. We understand the unique challenges of testing systems with limited memory, processing power, and no traditional OS.
Cloud and Edge Infrastructure
Device-level testing is only part of the story. We audit the cloud backends, device management platforms, and edge computing infrastructure that IoT products depend on - identifying exposures across the full deployment.
Our approach
Testing for the full device lifecycle
Our assessments go beyond short-term go-to-market needs. Connected devices may operate for years or decades, often in environments where they cannot be easily updated. We evaluate security across the entire product lifetime - from secure provisioning and secret management through long-term credential rotation and end-of-life decommissioning.
We combine automated analysis with hands-on manual testing. Automated tools help us triage and identify focal areas, but the real findings come from interactive security testing by engineers who understand device architectures.
How we work
Our process
Step 1
Scoping
We map your device ecosystem - hardware, firmware, protocols, APIs, and cloud infrastructure - to define the attack surface and prioritize testing objectives.
Step 2
Kickoff
We set up test environments, acquire device samples, and work with your engineering team to understand the architecture, communication flows, and security controls.
Step 3
Execution
Layer-by-layer testing from hardware through cloud - firmware extraction, protocol analysis, API testing, and infrastructure review. Critical findings are reported immediately.
Step 4
Reporting
Detailed findings with reproduction steps, severity ratings, and recommended mitigations. We present to both security and engineering stakeholders and support remediation efforts.
