- SEALSQ's (LAES, Financial) quantum-resistant microcontrollers enhance smart grid resilience against environmental and cyber threats.
- Following a massive blackout in Spain and Portugal, SEALSQ underscores the importance of secure data from IoT sensors in real-time monitoring systems.
- Their technology supports the integration of renewable energy and enables automated anomaly responses to prevent broader system failures.
SEALSQ Corp (NASDAQ: LAES) has announced its quantum-resistant secure microcontrollers designed to bolster the resilience of smart grids and IoT devices, particularly in the wake of environmental and cybersecurity threats. This announcement comes on the heels of a large-scale power outage that affected millions in Spain and Portugal on April 28, 2025. The blackout was triggered by temperature-induced vibrations in high-voltage transmission lines, leading to a cascade of synchronization failures and a subsequent loss of 15 gigawatts of power.
In response to these vulnerabilities, SEALSQ's technology secures IoT sensors and monitoring devices across electrical networks. Their microcontrollers ensure data authenticity and integrity, critical for early detection of anomalies such as temperature swings or synchronization issues. This capability allows grid operators to act quickly, potentially isolating faulty segments to prevent further cascading failures.
CEO Carlos Moreira emphasizes the importance of secure data transmission for the effectiveness of IoT sensors in smart grids. He noted that SEALSQ's solutions empower grid operators to trust real-time data and respond proactively to potential disruptions before they escalate into major faults.
SEALSQ's secure microcontrollers not only protect against current cyber threats but are also equipped with post-quantum cryptographic algorithms. These algorithms are designed to withstand next-generation cyber-attacks, including those posed by the advancement of quantum computing.
The technology offers tamper-proof data collection and enables rapid automated responses to grid anomalies. Furthermore, SEALSQ supports the integration of renewable energy by ensuring secure data at interconnection points, maintaining voltage stability, and enhancing operational efficiency under volatile conditions.
With global critical infrastructure facing increasing challenges from both environmental changes and cyber threats, SEALSQ is committed to offering cutting-edge, quantum-resistant solutions to safeguard essential systems and enhance overall grid resilience.
