Embedded & Firmware Security Solutions
Secure boot, signing and key management designed in at architecture time.
Security that was designed in
Firmware security tends to arrive late — usually when a customer asks how images are signed, or when a device is found to be physically reachable by people nobody vetted. Retrofitting a boot chain at that point is expensive, and the pieces required are nearly always the same.
The chain, end to end
A verified boot chain where each stage authenticates the next. Image signing with RSA or ECC, wired into the pipeline so every build is signed without a manual step. Keys generated and held in an HSM, never present in a build artefact. Anti-rollback so a device refuses an older, vulnerable image. Attestation so it can prove in the field what it is running.
Assessment of what already exists
For devices already designed or already shipped, we start with a review: attack surface, update path, debug interfaces, key handling, and what an adversary recovers from hardware they physically hold. The result is a prioritised list of what to fix, in the order that reduces risk fastest.
Where this comes from
This is not a separate practice bolted on. It comes out of defense and medical programmes where firmware provenance had to be demonstrable, and out of the toolkit our own engineers use on that work.
Secure boot chains
Each stage verifies the next before handing over control, from ROM to application.
Code signing
RSA and ECC signing wired into the existing build pipeline, with no manual step to forget.
HSM and key management
Private keys stay in hardware. They never reach a developer machine or a build artefact.
Vulnerability assessment
Review of an existing device — attack surface, update path, debug interfaces left open, secrets in the image.
Compliance support
Evidence and documentation for FIPS and ISO processes, produced alongside the work rather than reconstructed later.
Secure communications
Mutual TLS and attestation so a device can prove what it is and what it is running.
