Secure Boot 2026 · Industrial device security
Certificates expire. Your product lifecycle must continue.
Assess the 2026 Microsoft Secure Boot transition, strengthen your chain of trust and plan long-term security for embedded products.
Request an engineering assessment →What changed — and what did not.
Microsoft is transitioning UEFI Secure Boot certificates originally issued in 2011. Certificates began expiring in June 2026; another Windows boot-signing certificate expires in October 2026. This does not automatically stop devices booting or ordinary Windows updates. Devices without updated trust material may miss future early-boot security protections. Compatibility depends on OEM firmware and each boot chain.
Where ArivEmb can help.
We assess actual platform exposure before proposing firmware changes or an operating-system migration.
Bootloader and update engineering
OEM-coordinated UEFI updates where supported, verified Linux boot chains, firmware signing, pilot testing and recovery validation.
Windows IoT lifecycle assessment
Review support deadlines, product constraints and whether maintained Windows, Yocto Linux or another platform is appropriate.
Root of Trust and key ownership
Hardware-backed key storage, secure provisioning, U-Boot verified boot, MCUboot, anti-rollback and controlled debugging.
Secure OTA and recovery
Signed firmware updates, recovery paths, interrupted update testing and deployment safety for field devices.
CRA and long-term maintenance
SBOMs, vulnerability remediation processes, validation evidence and a defined product-security maintenance plan.
Start with the device
What we need for a first assessment.
Do not send confidential firmware, signing keys or customer data in an initial enquiry.
- Device type, OEM and processor or SoC
- Operating system, version and bootloader
- UEFI/BIOS or firmware versions, if available
- Number of affected devices and update limitations
- Test hardware availability and required support horizon
Engineering assessment
Is your industrial product affected?
Bring us your platform details. We will determine whether this transition applies and identify feasible remediation or modernization paths.

Not every IoT product relies on Microsoft certificates. Zephyr and FreeRTOS microcontrollers with separate secure boot chains are normally outside this particular UEFI transition. Some remedies require OEM firmware support or authorized updates. ArivEmb is an independent provider, not affiliated with Microsoft; CRA engineering is not a certification or legal compliance guarantee.
