The Quantum-Safe Sentinel #6 – March 2026
🏴☠️This month, regarding the quantum threat, we’ll talk about a new algorithm that may widely overtake Shor’s. While the news remains unreliable, the risk of sudden progress in that field has to be kept in mind.
🛡️PQC reaches a key inflection point, but while breakthroughs are important, there are still blind spots to address.
⚛️ Regarding Quantum Cryptography and QKD, we’ll see that initiatives are becoming global and opening a new era in this field.
➡️ Awareness Topic of the Month — We focus on HSMs and PKI, now emerging as some of the most critical cryptographic assets at risk. This edition introduces a Quantum Exposure Map to help identify and prioritize these vulnerabilities.
Bitcoin face à la menace quantique : panique exagérée ou vrai risque systémique ?
La sécurité de Bitcoin repose sur plusieurs briques cryptographiques distinctes, dont certaines résistent bien au quantique, tandis qu’une en particulier – le schéma de signature elliptique (ECDSA/Schnorr) – est vulnérable à l’algorithme de Shor. Dans ce contexte, deux visions s’opposent : pour les uns, la menace est sérieuse mais maîtrisable ; pour les autres, elle pourrait déstabiliser profondément l’écosystème si elle est sous‑estimée.
The Quantum-Safe Sentinel #5 - February 2025
💶 This month, we look at the cost of ignoring the quantum threat.
🛡️We’ll examine how PQC adoption is progressing anyway, driven by regulators, standards bodies, and early deployments.
⚛️ And we’ll review recent advances in quantum cryptography that show the ecosystem is maturing faster than many assume.
➡️ Our awareness topic focuses on the cryptographic inventory - the boring, uncomfortable, but absolutely unavoidable starting point of any serious PQC transition.
2026, the year of Post-Quantum Cybersecurity Planning
In our last newsletter, we highlighted a critical shift in the quantum cyber threat landscape: governments, industry leaders, and standards bodies are converging on concrete PQC implementation schedules. This edition of QS Lens provides a deep dive into that news to provide clear elements on why 2026 is the definitive turning point year for planning your migration to Post-Quantum Cryptography (PQC).
In this article, we outline the positions of key global stakeholders on the timeline for PQC adoption, then explain the fundamentals required to initiate a PQC transformation, before providing CISOs with a practical to-do list for 2026.
The Quantum-Safe Sentinel #4 - January 2026
We said it last month, and we will repeat it all year long: 👉🏽 2026 must be the year of Quantum Cybersecurity Planning. No more delays. Leading CISOs and CIOs who want to be ready on time must start planning their transition now.
Quantique & Cybersécurité : le Livre Blanc
Les technologies quantiques ne relèvent plus de la prospective lointaine. Leur montée en maturité, combinée à l’évolution rapide des cadres réglementaires, impose aujourd’hui aux organisations de structurer une vision claire des risques et des opportunités associés.
À l’occasion du Colloque 2025 du Forum des Compétences “Quantique et Cybersécurité”, QuRISK a contribué aux travaux collectifs et propose, dans cet article, une synthèse des enseignements-clés.

The Quantum-Safe Sentinel #3 - December 2025
As we close out 2025, this month brings a mix of progress and persistent challenges: successful tests of PQC in critical payment systems, alarming delay in enterprise adoption, and continued evolution of quantum cryptography technologies.
As always, we conclude with a focused awareness topic. This month, we address The Enterprise Readiness Gap, examining why organizations remain unprepared despite growing awareness.
A Guide to Quantum Security Concepts
As quantum computing advances toward practical reality, the cybersecurity landscape is undergoing a fundamental transition for “quantum-proofing”. Yet confusion persists around the terminology that defines this transition. If you've found yourself puzzled by terms like PQC, QKD, or "quantum-safe", you're not alone.
Let’s clarify these critical concepts that will shape the future of digital security.
The Quantum-Safe Sentinel #2
Welcome to the second edition of our Quantum-Safe bulletin. Last month’s inaugural version received exceptional interest, and we want to thank all of you for your feedback and engagement. It reinforced a belief we hold strongly: awareness and continuous learning are essential foundations for achieving cyber resilience.
The Quantum Talent Gap
Most people start to understand that Quantum Technologies will be the next game changer after AI. However, few realize the challenges created by the shortage of quantum-trained professionals, and how this will impact IT, cybersecurity, and business in general.
The Quantum Threat looms over Banking
A Europol-led initiative, the Quantum Safe Financial Forum, has sounded the alarm for Europe’s banks and financial institutions: the time to prepare for quantum risk is now.
The Quantum-Safe Sentinel #1
Welcome to the inaugural issue of QuRISK’s monthly bulletin, launched in celebration of Cybersecurity Awareness Month.
This new series is dedicated to shedding light on the rapidly evolving quantum cyber threat landscape and the emerging quantum-safe solutions: from Post-Quantum Cryptography (PQC) to Quantum Key Distribution (QKD) and beyond.
Each month, QuRISK will bring you a curated selection of insights, including key awareness points, the latest industry news and regulatory updates, and a spotlight feature on a timely quantum security topic.
5 Steps to Crypto-Agility Before PQC Implementation
Quantum computing is no longer a distant concern. With the European roadmap setting 2030 as the deadline for transitioning high-risk systems to Post-Quantum Cryptography (PQC), organizations need to act now. It's time for all CISOs to proactively address the "quantum shift" and consider a structured, long-term response. Let's explore the possible solutions and understand why crypto-agility is, without a doubt, the mandatory prerequisite, before detailing the steps to becoming a crypto-agile organization.
QKD standards: from Theory to Practice
In this article, we expose how QuRISK, as a risk company specialized in emerging technologies, is tackling the QKD security standardization subject. We will delve deeper into what these standards cover.
This article is a first result of a collaboration with EPITA’s Quantum Major students and VeriQloud - a leading French company in Quantum Communication - that offers cutting-edge QKD systems. The goal of our project is to propose innovative and efficient methods for analyzing and practically testing the compliance of QKD systems.
Why We Need Standardization of Quantum Key Distribution Networks
As quantum computing comes to the fore, many organizations are starting to plan their migration to innovative cryptography solutions. Adopting Quantum Key Distribution (QKD) is a good response to upcoming cyber threats related to communication. It necessitates standardized networks, and here’s why.
