What is Device Firmware Update?

A device firmware update is the process of installing a newer version of firmware, the low-level software embedded in hardware components, to improve security, fix bugs, enhance stability, or add new functionality. Unlike operating system updates, firmware updates modify low-level software such as BIOS or UEFI firmware, and the firmware embedded in SSDs, network adapters, docking stations, and peripherals.

Firmware updates are an important part of endpoint security because outdated firmware can contain exploitable vulnerabilities, including platform firmware flaws that may affect a device before the operating system loads.

Why are device firmware updates important?

Firmware is low-level software embedded in hardware that initializes, controls, or supports the operation of specific device components. If firmware contains known vulnerabilities or defects, attackers may exploit them to gain unauthorized access, establish persistence, or disrupt system operation, depending on the affected component and vulnerability.

Regular device firmware updates help organizations:

  • Patch known security vulnerabilities.
  • Improve hardware reliability and performance.
  • Maintain compatibility with newer operating systems.
  • Fix stability and hardware specific issues.
  • Support organizational security policies and applicable compliance requirements that require vulnerability remediation or secure system maintenance.

Organizations should include firmware updates in their risk-based patch and vulnerability management processes alongside operating system and application updates.

Device firmware update vs. software update

Feature  Device firmware update  Software update 
Updates  Embedded firmware  Operating systems, applications, drivers, and other software 
Purpose  Improve hardware functionality, security, and compatibility  Add features, fix bugs, improve security, and enhance user experience 
Examples  BIOS/UEFI firmware, SSD firmware, Thunderbolt controller firmware, network adapter firmware  Windows updates, macOS updates, Microsoft Office updates 
Hardware dependency  Targets software embedded in or closely associated with hardware  Targets operating systems, applications, drivers, or other software components 
Frequency  Varies by hardware vendor and component  Varies by software vendor, product, and release cycle 

Challenges of managing firmware updates at scale

Firmware updates are often more complex than software updates because they are hardware-specific and depend on factors such as device model, manufacturer, firmware version, and compatibility requirements.

IT administrators commonly face challenges such as:

  • Tracking firmware versions across diverse devices.
  • Scheduling updates without disrupting users.
  • Verifying update success.
  • Coordinating updates across devices from multiple hardware vendors.
  • Maintaining consistent security across distributed workforces.

Where supported by the device platform and management solution, centralized endpoint management can improve update visibility, deployment consistency, and reporting.

How Hexnode helps simplify endpoint update management

Firmware packages are typically developed and distributed by hardware manufacturers. Hexnode UEM centralizes supported operating system and application update management while providing remote firmware deployment for compatible Zebra printers running Link-OS 5.0 or later.

From a unified console, administrators can automate supported OS update policies across Windows, macOS, Android, and iOS devices. Hexnode also supports maintenance windows for certain Windows and macOS application update workflows, while compatible Zebra printer firmware can be remotely deployed using Hexnode. This centralized approach helps reduce manual administration and improve consistency across supported device management workflows.

Conclusion

Device firmware updates are an essential part of endpoint lifecycle management. Keeping firmware current helps reduce security risks, improve hardware stability, and maintain compatibility with evolving software platforms. Where supported, combining manufacturer-provided firmware updates with centralized endpoint management can improve deployment consistency, visibility, and operational efficiency.

FAQs

Yes. An interrupted or incompatible firmware update can leave a device unusable, which is why organizations should follow manufacturer guidance and verify compatibility before deployment.

Organizations can use hardware inventory tools, manufacturer management utilities, or endpoint management solutions that support firmware reporting for compatible devices.
