Post-Quantum Negligence: Legal Risks of Failing to Prepare for the Quantum Threat
Quantum computing is no longer a far-off hypothesis - it’s a rapidly emerging reality that could render today’s encryption obsolete. For CISOs and their boards, this means a new kind of cybersecurity crisis is on the horizon. Sensitive data that…

PQC First but Not Last for Quantum Resilience
Because of PQC upgrade challenges, an exclusive focus on “big‑bang” PQC migration can leave critical assets unprotected for years. Complementary mitigations such as hybrid key exchanges, tokenisation, crypto‑gateways, isolation tiers, confidential‑computing enclaves, PFED‑style dual‑layer encryptors, and even niche options like…

Sovereignty in the PQC Era: Standards, Trust, and Crypto-Agility
Post-Quantum Cryptography (PQC) is entering the standards stage, with the U.S. National Institute of Standards and Technology (NIST) recently selecting the first quantum-resistant algorithms. However, the future of PQC will not be as straightforward as simply adopting NIST’s choices globally.…

Trust Now, Forge Later (TNFL) – The Overlooked Quantum Threat
What is "Trust Now, Forge Later" (TNFL)? Most discussions about quantum computing threats focus on “Harvest Now, Decrypt Later” (HNDL) - the idea that adversaries can collect encrypted data today and store it, hoping a future quantum computer will break…

Quantum Readiness Is Not (Just) a Vendor Problem
In the recent IBM's “Secure the Post-Quantum Future” report 62% of executives admitted that their organization is waiting for vendors to make them quantum‑safe. In other words, they expect cloud providers, network equipment makers and software vendors to embed post‑quantum…

Quantum-Readiness / PQC Full Program Description (Telecom Example)
Preparing a large telecom (or any enterprise) for the post-quantum cryptography era is a massive, multi-faceted undertaking, but it is achievable with foresight, resources, and commitment. We’ve seen that it involves much more than just installing new algorithms - it’s…

Forget Q-Day Predictions – Regulators, Insurers, Investors, Clients Are Your New Quantum Clock
Whether you personally believe Q-Day will come in 5 years or 50, the world around you isn’t taking chances - and neither can you. As a CISO, you’re now being implicitly (and sometimes explicitly) told by every corner of your…

What 60+ Quantum Hardware Roadmaps Actually Tell Us
What do 60+ quantum hardware roadmaps tell us when you read them together instead of one at a time? This capstone article synthesizes the quantum computing company landscape into strategic insight: which modalities have the most commercial momentum, where the…

The Easiest Job in Quantum Computing – Being a Cynic
Don’t mistake the noise of cynicism for the signal of intelligence. If someone validates themselves as a useless cynic - unwilling to provide anything beyond scoffs and derision - don’t waste your energy getting dragged into their performative pessimism. Instead, direct…

Stop Asking What Number a Quantum Computer Factored. Ask These Five Questions Instead
One of the laziest talking points in quantum security is that quantum computing has “gone nowhere” because people still talk about factoring 15. That confuses an early proof-of-concept with the real engineering path to a cryptographically relevant quantum computer. The…

Device-Independent QKD (DI-QKD)
Modern quantum key distribution (QKD) has always carried a slightly uncomfortable subtext: the math may be information-theoretic, but the box on the rack is engineered. And engineered systems fail in messy, non-theoretical ways. That gap - between "provably secure on…

Marin’s Law on Crypto-Agility: Adaptability Determines Survivability
Thesis: Migration time to safer cryptography is inversely proportional to an organization’s crypto-agility. Formally: Let A denote an organization’s crypto-agility (0 ≤ A ≤ 1) and Y the wall-clock time required to replace a cryptographic primitive across all in-scope systems.…
