    Post-Quantum Cryptography (PQC) Standardization – 2025 Update

    Post-quantum cryptography (PQC) is here - not in theory, but in practice. We have concrete algorithms, with standards guiding their implementation. They will replace our decades-old cryptographic infrastructure piece by piece over the next decade. For tech professionals, now is the time to get comfortable with lattices and new key…

    How CISOs Can Use Quantum Readiness to Secure Bigger Budgets (and Fix Today’s Problems)

    Quantum readiness is not an exercise in science fiction – it’s a very practical program that yields benefits immediately. Regulators are pushing us all in this direction, which means boards are willing to fund it. The journey forces you to finally catalog your cryptographic assets and clean up long-standing weaknesses,…

    Quantum Computing Risks to Cryptocurrencies – Bitcoin, Ethereum, and Beyond

    Cryptocurrencies like Bitcoin and Ethereum derive their security from cryptographic algorithms – mathematical puzzles that are practically impossible for classical computers to solve in any reasonable time. However, the emergence of quantum computing threatens this security assumption. Unlike classical machines, quantum computers leverage quantum mechanics to perform certain computations exponentially…

      Balancing Quantum Computing Hype and Hope

      Quantum computing stands at the intersection of immense promise and intense hype. As someone who had led cybersecurity teams (including serving as an interim CISO for Fortune 500 companies) and was now investing in a quantum computing startup, I found myself navigating two contrasting narratives. On one hand, I am bullish on the future of quantum technology - convinced that within 15-20 years we’d see…

      Quantum Computers Intro

      I remember the first time I heard the phrase “quantum computer” about a ten years ago. I pictured something out of a sci-fi movie - maybe a glowing box humming with mystical power. As a techie who spends a lot of time worrying about encryption and security, my skeptical eyebrow immediately went up. Quantum anything has a way of making people lose their minds a…

      Are Quantum Computers a Real Threat?

      Our conclusion is that quantum computers are not an imminent threat to cybersecurity. They are a fascinating technology and potential threat in the long term, but certainly not something that keeps me awake at night today. For our clients such as governments and critical infrastructure operators, the prudent advice is to stay informed and begin long-range planning, but there’s no need to panic or overhaul…

      Quantum Snake Oil

      Don’t get me wrong - as a techno-geek at heart, I love the science of quantum computing. One day, it will upend cryptography as we know it. We’ll have to transition to new algorithms. That day will come - but it’s not here yet. It’s not even peeking over the horizon. Chasing every quantum-proof snake oil cure now is not just silly - it’s a…
