Post-Quantum Migration: The Next Phase

Post-Quantum Migration: The Next Phase

The Quantum Dragon worries about the future. Cryptographically relevant quantum computers are coming and, let’s face it, we’re not prepared for that. The market is splitting between early movers and laggards, and even the early movers need to consider how long their respective migrations will tak...

Why this matters
Why now

The accelerating development of quantum computing capabilities is forcing industries to confront the imminent threat to current cryptographic infrastructure, necessitating immediate planning for post-quantum migration.

Why it’s important

Failure to address post-quantum migration poses a severe national security and economic risk, as existing data and communications could be compromised by future quantum computers.

What changes

The urgency around post-quantum cryptography is increasing, driving a clear market split between proactive and reactive organizations, with significant investment and strategic shifts required.

Winners
  • · Quantum security solution providers
  • · Early adopter governments
  • · Cybersecurity firms
  • · Academic cryptographic researchers
Losers
  • · Organizations with legacy IT infrastructure
  • · Governments unprepared for quantum threats
  • · Industries relying solely on classical cryptography
  • · Late movers in security modernization
Second-order effects
Direct

Widespread adoption of new cryptographic standards and protocols begins, driven by national security and financial sector mandates.

Second

Increased M&A activity in the cybersecurity sector as companies acquire post-quantum encryption expertise and solutions.

Third

The development of quantum-resistant hardware becomes a major competitive differentiator for technology manufacturers, impacting supply chains.
