The starting point is not technology. It is understanding. For CISOs, the most effective way to approach quantum readiness is not as a single large initiative, but as a series of structured, coordinated steps that build over time.
1 | Conduct a quantum risk assessment and build a cryptographic inventory
CISOs need to identify where long-lived sensitive data exists, determine how it moves through the environment, and create a "cryptographic bill of materials" (CBOM).
2 | Establish ownership and build alliances
CISOs should find allies in risk, regulatory compliance, and internal audit to elevate PQC to board-level visibility.
3 | Update procurement and third-party risk management
CISOs must begin updating procurement standards to prevent the introduction of new systems incapable of transitioning to PQC.
4 | Define a phased migration strategy based on cryptographic agility
CISOs should focus on cryptographic agility — the ability to swap out algorithms without rewriting applications or rebuilding infrastructure — to make a phased PQC migration feasible at enterprise scale.
5 | Upskill teams and educate stakeholders
CISOs are encouraged to lead educational and training campaigns for stakeholders across the organization, from the board to development teams.
