  • •CISA and partners released guidance for assessing vendor readiness for PQC.
  • •Current public-key cryptography is vulnerable to quantum computing threats.
  • •Organizations must engage vendors early to ensure a secure transition to PQC.

CISA, the Australian Cyber Security Centre, and the NSA released joint guidance on assessing vendor readiness for post-quantum cryptography (PQC). As quantum computing advances, current public-key cryptography is at risk. Organizations are urged to evaluate third-party vendors that provide managed services and cloud capabilities, especially for industrial control systems and IoT devices, which are vulnerable due to long lifecycles. The guidance includes vendor-neutral questions to help organizations determine if their vendors understand quantum-related risks and have plans for a secure transition to PQC. Early engagement with vendors is emphasized as critical for effective planning and implementation. The transition to PQC is necessary to protect systems from potential quantum threats before cryptographically relevant quantum computers become operational.

Common questions

What is post-quantum cryptography?
Post-quantum cryptography refers to cryptographic algorithms designed to be secure against the potential threats posed by quantum computers.
Why is vendor readiness important?
Vendor readiness is crucial because many organizations rely on third-party vendors for essential services, and their preparedness directly impacts the security of cryptographic implementations.
What should organizations do to prepare?
Organizations should proactively assess their vendors' understanding of quantum risks and engage with them to ensure a secure transition to post-quantum cryptography.
