Software can be patched. Hardware, once deployed, often can't. A security flaw in a physical device may persist for years across thousands of units already in the field.
Crimson Wall's hardware penetration testing service addresses the unique security challenges of physical devices — whether you're a manufacturer assessing a product before launch, or an organisation evaluating devices deployed in your environment. Our specialists examine hardware from multiple angles, assessing both the physical device and the firmware that controls it.
What we assess
Firmware Security
Analysis of firmware for hardcoded credentials, cryptographic weaknesses, insecure update mechanisms, and exploitable vulnerabilities.
Communication Interfaces
Assessment of all communication protocols — UART, JTAG, I²C, SPI, WiFi, Bluetooth, and other interfaces that could provide attacker access.
Physical Tamper Resistance
Evaluation of physical security controls and the potential for hardware modification, debugging port access, and chip-level attacks.
Cryptographic Implementation
Review of how cryptography is implemented — including key storage, algorithm choices, and the robustness of secure boot mechanisms.
What you get
- A comprehensive security assessment of your device before it reaches the market or expands in deployment
- Identification of vulnerabilities that cannot be patched remotely once devices are deployed
- Design recommendations for improving security in future product iterations
- Evidence of security due diligence for regulators, insurers, and enterprise customers
- Avoidance of the reputational and financial damage of post-deployment hardware security incidents
Pre-deployment is the right time: Unlike software, hardware cannot be patched over the air in most cases. Discovering a critical firmware vulnerability after 10,000 units have shipped is an entirely different — and far more expensive — problem than finding it before launch.
