In today's Coredump Session, Memfault’s François Baldassari and Chris Coleman unpack the sweeping impact of new IoT security regulations like the CRA and the Cyber Trust Mark. From shocking real-world exploits to smart compliance strategies, they explore what these changes mean for hardware teams and the future of connected devices. If you ship firmware or build IoT products, this one’s essential listening.

Key takeaways:

• IoT security is no longer optional—new regulations like the CRA and Cyber Trust Mark make it mandatory.
• Most connected devices today are still dangerously undersecured, with outdated stacks and poor OTA support.
• Open source platforms like Zephyr can make compliance easier by pooling security resources across companies.
• OTA (over-the-air) updates are now a requirement in both US and EU regulations.
• The CRA introduces SBOM (Software Bill of Materials) requirements to track vulnerabilities in dependencies.
• Observability, encryption, and secure boot need to be built in from the start—not as last-minute add-ons.
• Compliance will vary based on device criticality, but self-certification will be the norm for most companies.
• Ignoring security costs more in the long run—both in reputation and risk.
