Expert services for device security architecture
Some risks cannot be fixed with a checklist. Secure boot, key provisioning, trusted execution, debug locking, update recovery, and anti-cloning controls depend on early architecture decisions.
Device Prophet provides expert technical reviews and advisory services for embedded, IoT, and connected-product teams that need more than a generic compliance report.
Six focused engagements
Pick a specific architecture concern, or start broad with Device Security Architecture Review.
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
A structured architecture-risk report generated from the Digital Auditor's findings. Covers secure boot, key handling, firmware updates, debug exposure, anti-cloning, and regulatory-readiness mapping.
Free. No payment required. Available as a PDF download from the audit results page after you run the assessment.
Implementation Advisory & Security Automation
For teams that need help turning review findings into engineering practice: CI/CD security gates, firmware release workflows, SBOM/VEX handling, vulnerability-response evidence, signing-process design, security test integration, and product-security documentation.
Quoted based on scope and existing tooling.
Engagement models
Free assessment
Automated preliminary architecture risk check.
Technical triage
Short expert review of assessment results.
Fixed-scope review
Focused review of a specific product or subsystem.
Deep-dive audit
Broader expert assessment with written findings.
Implementation advisory
Secure boot, OTA, key management, provisioning, automation.
Retainer
Ongoing fractional embedded-security architecture.
Most expert engagements are quoted after technical triage. Small fixed-scope reviews are typically suitable for focused technical questions. Larger product-security reviews depend on product complexity, available documentation, required deliverables, and the level of engineering support needed.
Implementation support available
We define and validate the security architecture. We can work directly with your engineering team on secure boot, TrustZone partitioning, fuse and lifecycle strategy, key provisioning, OTA design, and validation. Where broader BSP, driver, or board-support work is needed, we coordinate with trusted embedded partners while remaining responsible for the security architecture.
