Quantum computing is no longer a distant theoretical concern. Adversaries are already executing harvest now, decrypt later campaigns, collecting encrypted data today with the expectation that future quantum capabilities will render current cryptographic protections obsolete. Organizations that wait for quantum computers to arrive before taking action will find themselves years behind in a transition that demands immediate attention. In this talk, Kevin Tackett will break down the real-world implications of quantum decryption threats and provide practical guidance for organizations at any stage of preparedness. Drawing from experience advising organizations on their cryptographic posture, he will explain which algorithms are at risk, what post-quantum cryptography standards are emerging, and how to build a realistic transition roadmap. The presentation will address the technical challenges of cryptographic inventory, the operational complexities of migrating legacy systems, and the strategic decisions leadership must make now to avoid painful remediation later. Attendees will leave with a clear understanding of the quantum threat timeline, actionable steps they can implement immediately, and frameworks for communicating these risks to executives and stakeholders who may dismiss quantum threats as science fiction. Whether your organization has not yet started the conversation or is already deep in transition planning, this session offers the technical depth and practical perspective needed to future-proof your cryptographic infrastructure before the clock runs out.
