Systems and security engineering services
Implementation, integration, investigation and review across cryptographic software, Linux systems and embedded security.
Discuss a projectThree areas of engineering
Choose the area that fits your problem. Implementation and independent review are both available.
Cryptographic software & integration
Signing, PKCS#11 and HSM integrations, provider testing and key-use workflows.
Linux internals & diagnostic tooling
Investigate library and kernel behavior, build diagnostic tools, and repair low-level integrations.
Embedded security & trusted computing
Design, implement or review secure boot, device identity, key protection and firmware updates.
Cryptographic software & integration
Building a signing service, changing a PKCS#11 provider or connecting an application to an HSM? Work through the integration between your application, cryptographic library and key infrastructure.
A typical task
Implement a signing flow that selects the right key and mechanism, handles provider failures and has checks your team can run. An investigation can reproduce an incompatibility or compare providers before you decide what to change.
Signing and PKCS#11 projectsLinux internals & diagnostic tooling
Unexpected Linux behavior, a difficult failure or a missing diagnostic tool? Bring the workload or low-level integration that is blocking progress.
A typical task
Build or adapt a diagnostic tool, repair an integration, or trace the library, provider and kernel paths used by a workload. The work can follow a problem across application and kernel boundaries.
Linux diagnostic toolsEmbedded security & trusted computing
Working on the trust path between a device and its service? Get help with secure boot, provisioning, protected keys, updates or attestation policy.
A typical task
Provision a device identity used by a backend service, protect its key, and carry that trust through signed updates and recovery. Review how verified or measured boot fits the chosen platform.
Embedded review topicsEmbedded architecture review topics
Explore a particular part of your device architecture, or discuss ongoing engineering support.
Device Security Architecture Review
Trust boundaries, threat model, lifecycle, regulatory mapping.
Secure Boot & Root of Trust
Boot chain, signing, rollback, fuses, recovery.
Trusted Execution & Key Protection
TrustZone / TEE, secure elements, TPM / HSM, identity, attestation.
Firmware, OTA & Lifecycle Security
Signed updates, rollback prevention, vulnerability response, evidence.
Anti-Cloning & Product Integrity
Debug locking, RDP, flash encryption, anti-counterfeit.
Fractional Embedded Security Architect
Ongoing senior security architecture support on retainer.
Device Security Gap Report
The optional Digital Auditor provides a preliminary architecture assessment from your answers, with a free report and PDF. It helps prepare a design discussion; runtime behavior and hardware attestation need their own evidence.
Start Free Design AuditSigning, release and security automation
Integrate a signing service, add security tests or improve firmware update checks.
Discuss implementation supportHow the work starts
01
Describe the problem
Share what you are building and where you need help. A short outline is enough to start.
02
Agree the work
Set the deliverables, access, checks and fee before starting. Implementation or investigation can be agreed directly.
03
Build and hand over
Receive the agreed changes or findings, with checks and handover notes. Any follow-on work is agreed together.
What are you working on?
Share the problem and the result you need. An initial conversation can help decide whether implementation, investigation or a review is the useful next step.
