Why we cannot wait for better post-quantum signature algorithms

Cloudflare security blog feed covering post-quantum cryptography migration, AI and frontier-model security, vulnerability discovery and response, threat-intelligence-driven WAF protection, OAuth and non-human identity security, MCP governance, client-side and account-abuse protection, and multi-vector attack investigation. The feed includes a response to the critical Linux “Copy Fail” privilege-escalation vulnerability, with no customer impact reported, but most entries are security guidance and product announcements rather than disclosures of new exploitable vulnerabilities.
