F5 report finds cloud-driven gains mask gaps in post-quantum cybersecurity readiness

• F5's 2026 cybersecurity report found post-quantum cryptography support at 54% of the top 1 million websites, largely driven by third-party defaults.
• Excluding Cloudflare-hosted sites, readiness falls to 22%, exposing limited progress in organizations' own migration efforts.
• Technical debt leaves 10.5% of websites unable to support TLS 1.3, a prerequisite for hybrid post-quantum encryption.
• Utilities, energy and other critical sectors rank among the least prepared, despite exposure to attacks harvesting sensitive data for future decryption.
• No industry exceeds 59% adoption, even including protection enabled by content delivery networks, underscoring broader migration gaps.
