Cyber ​​Resilience Act Summit
2025-10-13 - 2025-10-14
With the Cyber ​​Resilience Act (CRA), the European Union has established a minimum level of cybersecurity for all connected products. The CRA covers all products sold in the EU that contain “digital elements.” This includes the entire spectrum of embedded systems —from consumer electronics and household appliances to complex high-end industrial systems—if they can be connected to a network or even to another device.
The CRA has been in force since the end of 2024, and implementation must be completed in several steps by the end of 2027 at the latest. Embedded systems developers, as well as project managers and product managers, are therefore asking themselves: How do I proceed to ensure that my products meet the CRA requirements?
At the Markt&Technik CRA Summit, top-class speakers will demonstrate which strategies can be used to make embedded systems of varying complexity “CRA-safe.”
At the event, Zephyr Project’s functional safety expert Nicole Pappler will be giving a talk on “Preparing open source projects for the CRA”.
About the talk: With the entry into force of the EU Cyber ​​Resilience Act (CRA), manufacturers of connected products face new regulatory requirements for cybersecurity across the entire product lifecycle. The Zephyr project, an open-source real-time operating system (RTOS), addresses these requirements through targeted technical and organizational measures.
The key elements include:
Automated creation of software bills of materials (SBOMs) for transparent component tracking
Long-term security support (LTS) with regular vulnerability fixes
Integration into CVE award processes for structured security communication
Vendor-neutral governance and community-driven development that promotes industrial adoption
Zephyr thus provides a robust open source foundation for the development of secure, auditable, and CRA-compliant embedded systems.

Zephyr on Arduino? Arduino on Zephyr? // Zephyr Tech Talk #028
2025-11-20 15:00 - 16:00
Tune in on Thursday, Nov. 20 (9:00 AM EST / 3:00 PM CET) for a new Zephyr Tech Talk live stream!
Arduino has been around for over two decades and its simple programming model has been helping countless makers and developers bring their ideas to life. But what happens when you want the ease of Arduino alongside the power and flexibility of a real-time operating system?
In this new Tech Talk episode, we will be chatting with Martino Facchin and Leonardo Cavagnis from Arduino about the bridges that exist between Zephyr and Arduino, from being able to use Arduino APIs and libraries with any Zephyr-supported board, to how the official Arduino cores are leveraging features such as Linkable Loadable Extension (LLEXT). Whether you’re an Arduino veteran curious about real-time applications or a Zephyr user excited by Arduino community and hardware ecosystem, join us live and ask your questions to our speakers.
Zephyr Tech Talks are live streams organized by and for the Zephyr community. Join us live to ask your questions directly to our guests, or catch the recording anytime afterward.
