CISA and international partners issue post-quantum vendor procurement guidance
What happened.The Cybersecurity and Infrastructure Security Agency and allied intelligence partners published a 31-question procurement framework evaluating vendor post-quantum readiness.
Why it matters.Modern enterprise software architectures depend on third-party SaaS platforms, cloud infrastructure, and appliance firmware for encryption. When external vendors fail to migrate away from public-key algorithms, harvest-now-decrypt-later attacks threaten long-term corporate confidentiality. Chief information security officers should integrate the 31 questions into vendor procurement evaluations. Procurement leads should reject supplier contracts that classify post-quantum algorithms as premium add-ons.
