Series 18 – Episode 3 – security for embedded systems

In the rapidly evolving world of industrial technology, cybersecurity has become a critical concern for businesses across various sectors. swissbit is at the forefront of addressing these challenges with its Security Upgrade System.

Marx brings a unique perspective to the company's innovative approach. With a background in physics and extensive experience in embedded development and cybersecurity, Marx understands the complex landscape of protecting industrial and IoT devices.

The company's security solution addresses a common and dangerous scenario in industrial settings. Imagine an IoT device monitoring critical parameters in a remote location. Unbeknownst to the operators, an attacker could potentially retrieve credentials and send fake data, compromising the entire system's integrity and reliability.

swissbit’s security upgrade kit offers a powerful solution. By utilising advanced flash controllers, the system can protect data storage with unprecedented security. The kit allows for granular control over data access, including read-only protection and hidden data segments. This means critical configuration files, AI models, and log files can be securely stored and protected from unauthorised access.

One of the most significant advantages of the system is its ease of integration. The security upgrade can be implemented across various platforms, from Raspberry Pi to industrial controllers and IoT gateways.

The solution is particularly crucial for industries with critical infrastructure, including electricity, renewable energy, oil and gas, and water production. With the upcoming Cyber Resilience Act mandating stricter security measures, swissbit provides a practical way for companies to enhance their system security without complete redesign.

The company's innovative approach has already gained recognition, winning the Electronics Excellence Award at embedded world 2025. This accolade underscores swissbit’s commitment to making advanced security accessible to companies of all sizes.

Marx emphasises that cybersecurity is not about rocket science but about implementing best practices. The key is creating unique credentials, protecting critical assets, and staying ahead of evolving threats. As attack models change and insider risks become more complex, solutions like swissbit’s become increasingly important.

For companies struggling with cybersecurity in embedded systems, swissbit offers more than just a product – it provides a comprehensive approach to protecting critical infrastructure. With upcoming developments in post-quantum cryptography and secure storage, the company positioning itself as a critical partner in the fight against cyber threats.

Businesses interested in enhancing their system security can explore swissbit’s solutions through the website, community portal, and GitHub repository, where example codes and integration guides are available.
