F5 Labs released its 2026 State of Post-Quantum Cryptography Report, revealing that 54% of the world's top one million websites have adopted post-quantum security measures. The report highlights significant regional variance, with Ukraine leading global adoption rates at 65%.
Why it matters
As quantum computing threatens to overwhelm standard public-key encryption, the pace of cryptographic migration is hampered by rigid procurement cycles and data sovereignty requirements. Identifying which sectors and regions are lagging is critical for mapping the exposure of global infrastructure to future decryption risks.
Of the world's top one million websites, 54% currently support post-quantum cryptography. Adoption remains uneven across critical sectors, with the oil and gas industry reporting the lowest readiness at 34% compared to the 39% found in utility providers.
The players
F5 Labs
A research division within F5 Inc. that focuses on application security, threat intelligence, and digital infrastructure analysis.
The details
Post-quantum cryptography refers to cryptographic algorithms designed to withstand attacks from quantum computers, which threaten to break current public-key encryption methods. The report notes that many organizations achieve this readiness not through internal engineering, but by migrating to edge platforms that offload the complexity of post-quantum key exchange. This reliance on third-party edge services is a response to the intense pressure of data sovereignty rules and slow institutional procurement processes.

The Tech Race
The adoption of post-quantum protocols is increasingly dictated by the necessity of operational resilience, a trend underscored by the migration of Ukrainian digital infrastructure during hybrid warfare. While some nations have prioritized these updates, industries like oil and gas remain behind, highlighting a fragmented global race to secure infrastructure against future decryption threats.
Organizations relying on legacy infrastructure face an accelerated need to evaluate whether their current edge providers support post-quantum standards. In sectors like utilities and telecommunications, where adoption sits at 35% to 39%, technical teams should assess if their security posture requires a shift toward these newer cryptographic handshakes.
The takeaway
The gap between high-readiness nations and critical infrastructure sectors illustrates that organizational agility, not just technical capability, determines cryptographic survival. Watch for upcoming industry benchmarks to see if the laggard sectors, specifically energy and government, accelerate procurement to close the 20-point gap with global leaders.
