We protect your data and communications from the quantum cyber threat through our world-class expertise in post-quantum cryptography and solutions that combine post-quantum cryptography with quantum cryptography to provide an unmatched level of protection.
Co-founders of PORTYQ contributed and lead the development and advancement of the HQC algorithm, which was selected by the NIST as a the second and last one post-quantum encryption standard. This achievement highlights our deep expertise in PQC and especially in code-based cryptography and our active role in shaping the next generation of quantum-resistant algorithms and their deployment.
PORTYQ co-organized one of the first European conference entirely dedicated to quantum cybersecurity threat, bringing together leading experts from academia, industry and public institutions. This conference goal was to make people aware about the urgency of transitioning to quantum-safe solutions.
As part of the ORQESTRA project, supported by the EDF, PORTYQ is involved in the development of next-generation quantum-resistant communication systems. The project focuses on the integration of Post-Quantum Cryptography and Quantum Key Distribution into real-world infrastructures.

We are proud to have been awarded the Deeptech Prize at the Unitec Awards 2026, recognising the innovative and technological excellence of our solution.
Our PQC Embedded Library, a post-quantum encryption and signature solution for RISC-V and ARM embedded systems, is now listed in the capacitary offers catalogue of the Alliance pour la Confiance Numérique (ACN). Already evaluated by a CESTI through several CC-EAL5+ certifications of products integrating our library, it supports ML-KEM, HQC, ML-DSA and SLH-DSA algorithms. Link to the ACN catalogue page
PORTYQ was featured by the Agence de Développement et d'Innovation (ADI) of Nouvelle-Aquitaine in a testimonial on securing data against the quantum threat. Our Head of Product Portfolio, Evan Delaunay, shared how European projects accelerate our growth: laureates of two Horizon Europe calls on open source and digital sovereignty after joining a European Defence Fund project, with three of our five candidatures selected to date.

PORTYQ was among the 12 quantum startups selected to pitch at the 5th Tech Evening of the Mouvement des Entreprises de France (MEDEF), hosted at the CNRS with Quantonation. Before an audience of over 300 researchers, business leaders, investors and public decision-makers, our President Michel Seyrac presented our vision for securing data against the quantum threat and strengthening European technological sovereignty.
