A $10 million investment is fueling WISeSat. Space’s development of satellite technology designed to withstand attacks from future quantum computers, directly addressing U.S. quantum security objectives outlined in Executive Order 14412. The company, traded on Nasdaq as SAIQ, is integrating post-quantum semiconductor technology from its sister company, SEALSQ Corp (Nasdaq: LAES), to secure communications, digital identities and satellite operations.
“Security is a core differentiator in our strategy to build a satellite communications business serving governments, enterprises and critical infrastructure operators,” said Carlos Moreira, Founder and CEO of WISeSat. Space, as the company aims to establish a 100-satellite sovereign constellation by 2033.

WISeSat. This funding directly supports the integration of post-quantum cryptography into the company’s satellite communications and Internet of Things architecture, aligning with U.S. The company’s strategy centers on protecting communications, digital identities and satellite operations against both conventional and future quantum computing-based cyberattacks. The core of this enhanced security lies in combining SEALSQ’s post-quantum semiconductor technologies with trusted digital identity and cryptographic key management systems. Space’s existing network includes nine active low-earth-orbit satellites, supported by ground stations in Switzerland and Spain, forming the foundation for its Quantum Spatial Orbital Cloud, or QSOC.
While current satellite access does not yet universally incorporate the new hardware, the long-term roadmap targets a 100-satellite sovereign constellation by 2033, contingent upon securing further financing, achieving necessary technical advancements, obtaining regulatory approvals and confirming launch availability, WISeSat. Space says. Space. The company’s approach uses SEALSQ’s Quantum Shield QS7001 and QVault TPM platforms, incorporating NIST-standardized algorithms like ML-KEM and ML-DSA. ML-KEM functions as a key-encapsulation mechanism to establish shared secrets for secure communications, while ML-DSA is a digital-signature algorithm to verify authenticity and data integrity.
These algorithms are intended to complement hardware-based protection of cryptographic keys and trusted identities, providing a layered defense against evolving threats. The implementation of standardized algorithms is foundational, though WISeSat. Space emphasizes that end-to-end security also relies on effective integration and operational practices.
These include secure government and sovereign communications, enabling protected satellite connectivity for agencies and emergency-response teams, alongside sovereign identity and key-management arrangements. Critical infrastructure monitoring, using satellite-connected sensors for telemetry from energy installations and transport corridors, is another priority, with trusted device identities and authenticated messages ensuring data integrity. The architecture also aims to protect satellite command and software integrity through post-quantum signatures, verifying commands and updates to prevent unauthorized modifications.
Beyond these, the company envisions applications in remote industrial IoT and logistics, securing data from connected equipment and containers via satellite links, and long-term protection of sensitive information against “harvest now, decrypt later” attacks. “As satellites become increasingly critical infrastructure for our digital economy, protecting them throughout their operational lives is central to our value proposition,” Moreira added.
“Our ambition is to bring trust into every layer, from the semiconductor and connected device to the ground station and satellite. By integrating post-quantum technologies across connected devices, ground infrastructure and satellites, we aim to strengthen our competitive position, address demand for secure, sovereign communications and create long-term shareholder value.” Regulatory alignment and compliance will be assessed for each implementation against applicable standards, cryptographic module validation requirements, and customer procurement conditions, ensuring a comprehensive approach to post-quantum security.
Security is a core differentiator in our strategy to build a satellite communications business serving governments, enterprises and critical infrastructure operators.
