Two dates that should be on every CISO’s calendar right now

📅 September 21, 2026 — NIST’s CMVP moves every active FIPS 140-2 certificate to the Historical List. It doesn’t mean your crypto module is broken. It means federal agencies can no longer cite it to justify a new procurement. If … Read More

Let’s be brutally honest about the Post-Quantum Cryptography (PQC) migration: No single vendor or magic-bullet tool is going to make your entire enterprise “Quantum Safe” overnight.

With the recent White House Executive Order on PQC and NIST’s finalized standards (FIPS 203, 204, 205), the market is flooded with bold promises. But any experienced CISO or Enterprise Architect knows the technical reality: Cryptography isn’t a single switch … Read More

AI Just Entered the PQC Arena – Here Is What Security Executives Need to Know.

Anthropic’s recent preview of Claude Mythos demonstrated AI models semi-autonomously uncovering structural mathematical weaknesses in cryptographic primitives, most notably cutting the effective key strength of HAWK, a round 3 NIST PQC candidate, roughly in half. While HAWK is a candidate … Read More

Quantum Physics Just Broke Free from the Microscope – And Enterprise Security Needs to Pay Attention

For decades, we’ve treated quantum mechanics as a ghost story of the subatomic world, a bizarre set of rules that only applies to things we can’t see. But a groundbreaking new study just published in Nature Physics completely rewrites that … Read More

What Netflix’s ‘Dark’ and Quantum Mechanics Taught Me About the Illusion of Spacetime (and Leadership)

If you’ve watched Dark on Netflix, you know the horror of being trapped in an unyielding, repeating loop of time. It exploits our deep anxiety of being helpless passengers inside a rigid reality. But both quantum mechanics and ancient philosophy … Read More

How long would it take your team to map every single cryptographic asset across your entire enterprise footprint?

Days? Weeks? Months of tedious, manual internal audits? When CISOs and Enterprise Architects look at post-quantum migration, the sheer scale of the discovery phase can feel paralyzing. Cryptography doesn’t live in just one place. It’s buried in your source code, … Read More

The reality of Post-Quantum Cryptography (PQC) migration is that it is fundamentally a visibility problem.

As the cybersecurity conversation rightly elevates to a board-level risk imperative, leadership teams are realizing that quantum-related risks aren’t just a compliance checklist for tomorrow—they are active operational threats today. We are currently navigating two distinct fronts: The Passive Threat … Read More

Your quantum-safe data is secure from eavesdroppers. But what happens when an attacker uses Post-Quantum Cryptography (PQC) as a weapon against you?

Enter EPER (Encrypt with PQC, Enforce Ransom). We’ve spent years talking about HNDL (Harvest Now, Decrypt Later), the threat of adversaries stealing our data today to crack it with a quantum computer tomorrow. But the threat landscape has flipped. In … Read More

The Peloponnesian Trap: When Your Future Defense Becomes Your Enemy’s Weapon

Ask any executive about the Post-Quantum Cryptography (PQC) transition, and they will likely give you a fatigued response about “Harvest Now, Decrypt Later” (HNDL). The industry is tired of hearing it. By treating the quantum threat as a passive “tomorrow … Read More

What “Interstellar” Teaches Us About the Post-Quantum Cryptography Race

In the movie Interstellar, humanity faces a quiet, existential countdown. The planet is running out of time, and the only way to save civilization is to solve a seemingly impossible mathematical puzzle. The catch? The equations they are using on … Read More
