Decent Cybersecurity
Deep-tech firm developing post-quantum cryptography and quantum-resistant blockchain solutions for defence, space and critical infrastructure.
Decent Cybersecurity is a Piešťany, Slovakia-based deep-tech firm founded in 2015 by CEO/Chairman Matej Michalko, developing post-quantum cryptography and quantum-resistant blockchain solutions for defense, space, and critical-infrastructure applications. The company holds NATO, EU, and Slovak national 'Secret'-level security clearances, and maintains additional offices in the Czech Republic, Poland, Austria, Ireland, and the UK. Its product line spans post-quantum protocols for space/satellite communications (SpaceShield STM), unmanned traffic management (DroneCrypt UTM), and cryptographic key management, and it is exploring what it describes as the world's first 2nm post-quantum cybersecurity ASICs in collaboration with Japan's Rapidus Corporation. Decent Cybersecurity participates in multiple EU Horizon Europe / European Defence Fund consortia, including the €32M AIDA cyber-defense project (led by CR14, an Estonian MoD-affiliated foundation) and the €4M U-HARRIER heavy-lift UAV project (EDF 2025 cohort), and was selected for NATO DIANA's 2026 Decision Superiority challenge cohort.
