The essential role of cybersecurity – today and beyond

We live in a connected world where digital devices have become part of almost every aspect of our daily lives. From our homes and workplaces to our commutes and way of producing goods: connected devices simplify tasks, create efficiencies, and support the way we live and work. Connectivity is no longer a luxury - it has become a fundamental backbone of modern society.

As our world becomes more interconnected, protecting it becomes increasingly essential. Trust is the foundation of the connected world; without it, the systems and services we depend on could not function. In recent years, cyberattacks have increased steadily, and the rise of artificial intelligence is further accelerating this trend. Combined with established attack methods, AI provides malicious actors with more powerful tools to identify and exploit system vulnerabilities. In this environment, cybersecurity is not optional - it is a prerequisite for modern life.

Think of a smart home, where IoT devices such as cameras, thermostats, connected energy meters, and voice assistants promise convenience, efficiency, and automation. Without robust cybersecurity measures, these devices can become entry points for cyberattacks, putting personal privacy, safety, and even household energy systems at risk.

In the automotive sector, modern vehicles are equipped with sophisticated technologies like advanced driver assistance systems (ADAS), vehicle-to-road connectivity, connected infotainment platforms, and Software‑Defined Vehicle architectures. A breach in any of these systems could compromise not only sensitive driver data but also critical vehicle functions, directly impacting passenger safety. There is no physical safety without cybersecurity measures.

Beyond individual households and vehicles, cybersecurity is equally vital for critical infrastructure such as energy supply networks and power grids. As these systems become increasingly digitized and interconnected, cyber incidents could disrupt electricity distribution, affect industrial operations, or even cause large-scale outages.

Robotics and automation continue to evolve, bringing new opportunities while also introducing additional considerations for cybersecurity. From industrial robots on factory floors to service robots in healthcare and logistics, compromised robotic systems could lead to production failures, physical damage, or safety hazards for humans working alongside them. Looking ahead, the emergence of humanoid robots operating in public spaces, workplaces, and private homes will amplify these risks even further. As these systems increasingly interact with people, handle sensitive data, and make autonomous decisions, ensuring their cybersecurity will be essential to safeguard trust, physical safety, and societal acceptance.

On an even larger scale, it is essential that government-issued digital IDs, banking systems, and secured communications are well protected against cyber threats to prevent identity theft, fraud, and systemic disruption. Cybersecurity remains a crucial layer of defense in an ever-evolving and rapidly changing digital landscape.

Preparing for a post-quantum world

Quantum computers use the principles of quantum physics to process information in entirely new ways, giving them the potential to solve certain complex problems far faster than today’s computers. This future capability will unlock major breakthroughs. But this also means that many of today’s encryption methods could eventually be broken, making early preparation essential. As devices and digital services stay in use for many years, quantum‑resilient technologies like post‑quantum cryptography (PQC) are crucial to ensure long‑term protection against tomorrow’s attacks. With pioneering certified PQC solutions and advanced secured microcontrollers, Infineon is helping industries safeguard their data and systems well into the quantum era. Learn more about PQC here.

Regulations enable cybersecurity

International regulations and standardization are crucial for the success of cybersecurity. As an industry leader, Infineon actively contributes to initiatives such as the European Cyber Resilience Act (CRA), which aims to establish clear and enforceable cybersecurity requirements for digital products being sold within the EU market. By leveraging its extensive expertise in hardware-based security, Infineon helps shape the standards that address emerging cyber threats while supporting interoperability, scalability, and long-term reliability. At Infineon, the security and reliability of our products are central to our development approach. All our solutions are designed in accordance with the requirements of the EU Cyber Resilience Act, providing customers with products that meet contemporary regulatory standards and support a high level of protection.

Additionally, Infineon collaborates with international organizations, consortia, and regulatory bodies to develop standards for IoT security, automotive cybersecurity, and post-quantum cryptography. These efforts not only help comply with evolving regulations but also foster trust within the global market by promoting secured-by-design principles. Infineon’s proactive engagement in standardization underscores its commitment to creating a safer digital ecosystem and enabling innovation across critical sectors like smart homes, connected vehicles, and industrial automation.
