Decent Cybersecurity Eyes Japan Market With Post-Quantum Breakthrough

 Decent Cybersecurity, the only Slovak firm having a booth at DSEI Japan 2025, has effectively positioned itself for growth into the Japanese and larger Asian markets.

The company demonstrated three of its flagship post-quantum cryptography technologies—SpaceShield STM, DroneCrypt UTM, and the QuantumProof Protocol—at the esteemed defense exhibition in Chiba from May 21–23. These technologies are all intended to counter the growing threat that quantum computing poses to conventional encryption systems.

Key Highlights:

• Strategic Asian Expansion: Only Slovak firm at DSEI Japan, targeting Asian cybersecurity market.
• Quantum-Tech Showcase: Presented three post-quantum cryptography solutions to strong industry interest.
• Semiconductor Collaboration: Exploring 2nm post-quantum ASIC development with Rapidus in Japan.

"The response has exceeded our expectations," said Matej Michalko, CEO of Decent Cybersecurity. "Decision-makers from Japan's defense, aerospace, and government sectors have shown genuine interest in our quantum-resistant solutions, recognizing the urgent need to prepare critical infrastructure for the post-quantum era."

In a noteworthy move, Decent Cybersecurity is investigating the possibility of working with Rapidus Corporation to produce the first 2nm post-quantum ASIC microchips in the world in Japan with the help of the Slovak government. Together, Decent Cybersecurity's post-quantum cryptography experience and Rapidus's state-of-the-art 2nm semiconductor manufacturing capabilities would enable the creation of the first 2nm post-quantum cryptography ASICs (Application-Specific Integrated Circuits), marking a revolutionary breakthrough in quantum-resistant hardware security with cutting-edge technology.

The possible collaboration is a natural fit with Rapidus's goal of making Japan a global leader in the production of next-generation semiconductors. With Rapidus's pilot line testing starting on April 1 and the Japanese government providing 802.5 billion yen (US$5.4 billion) in subsidies for the company in fiscal year 2025, the timing of this partnership seems ideal.
