She outlines key timelines: the UK NCSC recommends full migration by 2035, while Google has set an internal deadline of 2029. Large organisations typically need five or more years for a full cryptographic overhaul. She identifies two common mistakes: treating post-quantum migration as a pure technology project rather than an organisational transformation, and starting with a cryptographic inventory before first clarifying what data needs protecting and for how long. Her Practical Post-Quantum Transition Framework is designed to deliver security improvements from day one and build crypto-agility across teams of any size. ## Full article daily.dev links to this article rather than hosting it.
