AI All-in-One series · Cryptographic transformation

Post-Quantum Cybersecurity All-in-One by Kai London

Quantum risk is a migration problem long before it is a mathematics problem. Data captured today can be decrypted later, and most enterprises cannot yet answer the first question: where is our cryptography? This handbook takes you from that inventory through to a funded, sequenced transformation.

What is inside

Quantum risk, honestly stated

What is actually at stake, which data has a long enough confidentiality horizon to matter, and how to brief a board without theatre.

Cryptographic inventory

Discovering algorithms, key lengths, certificates and hard-coded crypto across applications, appliances and third parties.

PKI, TLS and certificates

Certificate lifecycle, hybrid modes, and the operational reality of rotating trust at enterprise scale.

Crypto agility as an architecture

Designing so the next algorithm change is a configuration decision rather than a programme.

Identity, cloud and the supply chain

Signing, tokens, managed services and vendors whose migration timetable is not yours.

A sequenced migration plan

Prioritisation by data lifetime and exposure, with milestones a steering committee can track.

Who it is for: CISOs and technology risk leaders scoping a PQC programme, PKI and cryptography teams, security architects, and regulated firms being asked for a migration roadmap.

NIST PQC standardsISO/IEC 27001NIST CSF 2.0DORANIS2

You cannot migrate cryptography you cannot find. The inventory is the programme.
