Quantum Ready
is not just a warning; it’s a field guide for the era of quantum disruption. As quantum computing accelerates toward the threshold where today’s encryption becomes obsolete, organizations must prepare now or risk a catastrophic breakdown in digital trust.
Written by one of the world’s first Field CISOs, this book delivers a strategic, vendor-neutral roadmap for CISOs, security architects, and IT leaders responsible for protecting long-term data and infrastructure. It introduces the Q-Ready Framework, a comprehensive five-phase approach to discovering, prioritizing, migrating, validating, and sustaining quantum-safe cryptography across the enterprise.
In this hands-on guide, you’ll learn how to:
- Identify where vulnerable cryptography lives in your environment
- Evaluate business impact using real-world risk models like Mosca’s equation
- Design migration and testing plans tailored to your infrastructure
- Replace RSA, ECC, and other algorithms with NIST-approved quantum-safe alternatives
- Apply post-quantum cryptography to TLS, VPNs, code signing, and IoT
- Build crypto-agility into your systems, teams, and governance
With practical checklists, actionable advice, and insights from hundreds of field engagements, Quantum Ready goes beyond theory and into the trenches. Whether you’re already on your migration journey or just beginning to assess the threat, this book will prepare you to lead with confidence through one of the biggest shifts in cybersecurity history.
The clock is ticking. Read now, and be the reason your organization is still trusted tomorrow.
