Survey data from Sectigo suggests post-quantum cryptography has moved from awareness to budgeting, with 83% of organizations reporting funded initiatives.

Readers should note that this is a vendor-commissioned survey of 500 IT leaders, so the figures show sentiment and intent rather than verified migration progress.

78% of IT leaders anticipate significant changes to public key infrastructure (PKI) to support post-quantum cryptography, per new Sectigo research.

Sectigo research reveals that 38% of organizations have now fully assessed systems vulnerable to quantum computing attacks, a substantial increase from 14% in 2025. The 2026 State of Crypto Agility Report, based on a global study of 500 IT and security leaders, demonstrates a shift from awareness to active implementation of post-quantum cryptography initiatives. Eighty-three percent of organizations have already budgeted for these initiatives, and 93% anticipate increased investment over the next two to three years. “Organizations have moved…
