The clock is ticking. At Davos 2026, IonQ’s CEO warned that Q-Day, when quantum computers can break today’s encryption, may arrive within three years. Google has compared quantum computing’s current trajectory to AI five years ago, just before its explosive growth. Yet according to Bain & Company, 90% of executives still lack a quantum security…
Decent Cybersecurity s.r.o. has formally launched a new research and development project focused on secure communications for space applications, with a total project volume exceeding €4 million. The project is funded under Program Slovensko 2021–2027 and co-financed by the European Regional Development Fund. The project, titled Bezpečná komunikácia vo vesmírnom výskume (Secure Communication in Space…
The rise of quantum technology is fundamentally shifting digital security. To address new challenges, Decent Cybersecurity collaborated with Frequentis and the Slovak Ministry of Foreign and European Affairs at an Innovation Day. This gathering represented the 34th edition of the Innovation Day series. Our primary goal involved quantum-proofing future critical infrastructure through advanced technological cooperation…
Decent Cybersecurity attended the conference “Cybersecurity in Transport and the new directive NIS2” on 24 November 2025 in Košice.
