The conversation dives into the complexities of creating a cryptographic inventory – the "step zero" for any migration – and the technical hurdles of deploying NIST-standardized algorithms like ML-KEM. From addressing the "store now, decrypt later" threat model to overcoming middle-box bugs caused by larger packet sizes, the experts share a roadmap for achieving true crypto agility. They emphasize that PQC readiness is not a one-time fix but a continuous organizational muscle required to maintain digital trust as global standards and quantum capabilities evolve.

In this segment from DigiCert World Quantum Readiness Day, Lakshmi Hanspal, chief trust officer at DigiCert, and Colin Soutar, global quantum cyber readiness lead at Deloitte, join theCUBE’s John Furrier to discuss the evolution of quantum threats from theoretical concepts to board-level risk priorities. Hanspal and Soutar explore how organizations are moving beyond "kicking the tires" to building formal roadmaps, fueled by an uptick in executive awareness and the necessity of cryptographic modernization. They unpack the "urgency paradox" – the challenge of investing in security for threats that have not yet fully materialized – and define what success looks like through quantum-safe design, crypto-agility and the ability to swap algorithms without disrupting business operations.

The discussion also dives into the quantifiable cost of inaction, highlighting the "Harvest Now, Decrypt Later" phenomenon and the emergence of a "two-tiered trust" system where non-compliant organizations risk being excluded from secure digital ecosystems. Soutar and Hanspal emphasize that post-quantum cryptography (PQC) updates should be integrated into existing Public Key Infrastructure (PKI) modernization projects and shortening certificate lifecycles rather than treated as a siloed effort. From hitting critical milestones like inventory discovery to securing cross-functional sponsorship, the guests provide a practical blueprint for articulating the return on investment to the CFO and maintaining competitive positioning in an evolving regulatory landscape.

In this segment from DigiCert World Quantum Readiness Day, Jeremy Rowley, senior vice president of strategy at DigiCert, is joined by Jeff Stapleton, PQC researcher and architect at Wells Fargo, and Tom Patterson, managing director at Accenture, to discuss "Practical First Steps" for post-quantum cryptography (PQC) migration. The panel explores the critical role of pilots in validating technical approaches and making quantum risks tangible for organizational leadership and boards. The experts break down the phased approach to migration, distinguishing between proofs of technology, proofs of concept and production pilots to ensure a seamless transition from the lab to the enterprise.

The conversation emphasizes the urgency of starting cryptographic transitions today, noting that industry-wide shifts can take decades to complete. Stapleton and Patterson highlight the importance of crypto-agility, which allows organizations to switch to NIST-standardized algorithms without overhauling their entire infrastructure. Key takeaways include utilizing risk-based assessments to prioritize migration efforts and the necessity of engaging the broader vendor ecosystem early to ensure interoperability. The session provides a clear roadmap for turning quantum readiness into a funded, strategic business priority before "Q Day" arrives.

In this DigiCert World Quantum Readiness Day segment, theCUBE’s John Furrier hosts a discussion on the critical necessity of assessing vendor readiness for a post-quantum world. Joined by Kevin Hilscher of DigiCert, Konstantinos Karagiannis of Protiviti, and Blair Canavan of Thales, the panel explores why enterprises cannot simply wait for a software patch to resolve quantum vulnerabilities. Karagiannis outlines the significant "quantum technical debt" legacy organizations face and explains how to conduct maturity assessments that focus on a vendor's crypto-agility, roadmap transparency and implementation of hybrid cryptographic approaches.

The conversation also dives into the practical steps for securing the software supply chain, with Canavan detailing how Thales is "walking the walk" by integrating post-quantum support into hardware security modules and key management platforms. The experts highlight the importance of identifying red flags – such as vague or non-committal responses – and advise organizations to begin incorporating specific PQC requirements into RFIs and RFPs. With potential quantum breakthroughs projected as early as 2030, the discussion emphasizes the urgent need for certificate lifecycle automation and proactive collaboration to ensure cryptographic resilience.

In this segment from DigiCert World Quantum Readiness Day, theCUBE’s John Furrier explores the technical path to post-quantum security with Shane Kelly, principal crypto architect at DigiCert, Dr. Lily Chen, NIST Fellow, and Panos Kampanakis, principal security engineer at AWS. The panel breaks down the practical application of ML-KEM, the recently standardized alternative to legacy RSA and ECC schemes. The experts highlight the immediate need for migration to counter "harvest now, decrypt later" attacks, where adversaries collect encrypted data today to compromise it once a relevant quantum computer exists.

The discussion dives into the strategic deployment of hybrid cryptographic methods, specifically the X25519 ML-KEM 768 scheme utilized by industry leaders like AWS to ensure a conservative and secure transition. The guests analyze why ML-KEM is considered secure for government and customer data, the role of FIPS 140 validation in hybrid implementations, and the importance of building crypto-agility through modular software libraries. From prioritizing high-impact use cases to meeting the NIST 2035 transition framework, the conversation provides a clear roadmap for enterprise quantum readiness at scale.

In this segment from DigiCert World Quantum Readiness Day, theCUBE’s John Furrier is joined by Corey Bonnell, industry development strategist at DigiCert, Richard Kisley, chief engineer at IBM, and William Whyte, senior director of technical standards at Qualcomm, to discuss the technical evolution of ML-DSA.
