Over-the-air (OTA) firmware updates are one of the most powerful tools in modern IoT development—and one of the most dangerous if implemented poorly. Without proper security, firmware updates can expose systems to cyberattacks, device takeovers, or complete network failures. At Cedarware, secure IoT firmware update architecture is a top engineering priority.

Why Secure OTA Updates Matter

Firmware updates allow manufacturers to:

●        Patch security vulnerabilities

●        Add new features

●        Improve performance

●        Fix bugs remotely

●        Extend product life

But unsecured updates can allow hackers to inject malicious code directly into your devices.
