WISeSat.Space Takes Quantum Leap with Secure IoT Satellites Amid Growing Space Cybersecurity Threats

GENEVA – September 12, 2023: WISeKey International Holding Ltd. (“WISeKey”) (SIX: WIHN, NASDAQ: WKEY), a global leader in cybersecurity, digital identity, and Internet of Things (IoT) solutions operating as a holding company, announced today the launch of an ultra-secure picosatellite solution via its subsidiary WISeSat AG. This initiative is specifically designed for the Quantum-Ready Internet of Things (IoT) communications market.

The cybersecurity landscape of space is rapidly changing, and with it, the threats faced by satellites. A startling revelation last April saw hackers from Thales Alenia Space manipulating ESA’s OPS-SAT spacecraft, affecting its operations and imagery. As if that wasn’t alarming enough, a leaked U.S. intelligence report divulged China’s exploration into cyber weapons, capable of overtaking enemy satellites during wartime scenarios. This growing list of concerns also includes the significant disruption caused by the cyber-attack on Viasat’s broadband service last year.

WISeSat.Space, alongside SEALSQ, is addressing these concerns head-on with their groundbreaking collaboration. By incorporating the VaultIC408 secure element, they are fortifying each endpoint within the satellite network. This initiative promises businesses, irrespective of their size, a cost-effective, ultra-secure means to establish their digital ecosystems.

Seventeen WISeSat-ready satellites have already made their journey into space via SpaceX, part of an ambitious 80-satellite constellation that aims to offer unparalleled global IoT connectivity and a remarkable data latency of just 10 hours.

But the vision doesn’t stop there. Embracing the quantum era, WISeSat.Space is fortifying its solutions against the potential threats posed by quantum computing. Implementing post-quantum solutions and robust devices, they’re setting the standard for secure multi-factor authentication and critical data transfer in the age of quantum computing.

For those keen on tracking the progress, the WISeSat-ready Fossa Satellites can be monitored in real-time at FossaSat-2E1. With a full constellation, users can witness an impressive revisit time of just 5 minutes.

Both SEALSQ and WISeSat.Space’s innovative strides demonstrate their unwavering commitment to tackling the multifaceted challenges of the digital realm.
