Embedded security and secure boot
Embedded security for devices that must protect firmware, updates, data and access. Support covers secure boot, firmware signing, key management, hardening, secure OTA and attack surface reduction.
Protect the firmware chain
For a connected product, security starts at boot and reaches updates, logs, credentials, exposed ports and maintenance procedures.
- Secure boot, signature verification, anti-rollback and firmware protection.
- Key, certificate, credential and secret handling in memory or storage.
- Hardening of services, debug ports, local interfaces and update channels.
- Risk analysis and technical priorities for existing devices.
What it includes
Controlled startup with image verification and recovery policy.
Signed updates, rollback, package integrity and update logs.
Reduce exposed ports, services, debug access and risky configurations.
Map critical issues and practical priorities to reduce exposure.
Working method
- Review goals, constraints, existing code, systems and business priorities.
- Define risks, architecture, measurable checkpoints and an execution plan.
- Implement or debug in verifiable steps on real data, code or hardware.
- Deliver code, documentation and decisions the team can maintain and evolve.

Frequently asked questions
Is this useful for products that are not connected?
Often yes, especially if firmware, data or debug access can be copied or altered.
Can we run an audit before implementation?
Yes. An initial audit avoids choosing mechanisms that do not fit the hardware or product lifecycle.
