Firmware, OTA & Lifecycle Security
A product is not secure at launch unless it can remain secure in the field.
Device Prophet reviews firmware update and lifecycle-security architecture, including signed updates, rollback protection, staged rollout, recovery behavior, vulnerability handling, support windows, and customer evidence.
Typical scope
- · Signed firmware update design
- · Rollback and downgrade prevention
- · Recovery and anti-bricking strategy
- · Update authorization model
- · Vulnerability response process
- · SBOM / VEX usage where useful
- · Lifecycle-support evidence for customers and regulators
Security automation and release evidence
For products with ongoing firmware releases, we can help design security gates and evidence workflows around signed firmware, update approval, vulnerability triage, SBOM/VEX handling, release documentation, and lifecycle support.
The goal is not "automated compliance." The goal is a repeatable engineering process that produces the evidence needed for customers, regulators, and internal product-security governance. This typically includes signing workflow design and the release signing process and key-handling model - not putting signing keys in CI/CD.
Outcome
You receive a written analysis of your firmware-update and lifecycle-security architecture with remediation options, evidence-package guidance, and engineering decisions to make before scaling production.
Our review process may use AI-assisted research and mapping to speed up standards analysis, requirement discovery, and preparation. Final findings and technical recommendations are reviewed by human embedded-security expertise.
