NIST IR 8547 (final) sets a timeline to deprecate quantum-vulnerable crypto after 2030 and disallow it after 2035, with US government mandates to adopt post-quantum cryptography for key establishment by end of 2030 and for digital signatures by end of 2031.

Federal deadlines create earlier migration targets for sensitive systems: high-value assets must adopt quantum-resistant key establishment by 2030 and quantum-resistant digital signatures by 2031, with TLS 1.3 support required by 2030 under related orders.

NIST updated IR 8547 to reflect EO 14412 timelines, emphasizing moving high-value assets to post-quantum key establishment by 2030 and to post-quantum signatures by 2031, while general disallowance remains set for 2035.

Hybrid cryptography is useful as a hedge but adds costs and complexity, and requires clear explanations of what is protected by deployed connections.

Migration will require coordinated changes across multiple components, with potential timing gaps between supplier updates and customer readiness.

The platform expands discovery through integrations with Qualys and Tenable, maintaining an agentless-first approach.

The report supports NCCoE’s migration-to-PQC project by distinguishing standards/guidance from practical implementation tools and blueprints.

IDC and AppViewX leaders stress the urgency of cryptographic exposure assessment and proactive remediation before PQC migrations.

Practical migration guidance emphasizes starting with a cryptographic inventory, planning by use-case (key establishment vs. signatures), and considering TLS 1.3 hybrid/pure paths and EOL timelines for long-lived hardware.

Also, testing TLS handshakes with ML-KEM-768, understanding ClientHello size implications, coordinating with load balancers and third-party services, and requesting roadmaps from HSM/TPM/smart-card vendors for ML-DSA and LMS/XMSS.

KXCO product line (Portcullis, Round Table, Herald, Sovereign, Guildhall, Hanse, Armature, Athanor) now forms a coherent post-quantum stack for signing, attesting, and identity management in an on-chain/consensus workflow.

Organizations should assess cryptographic supply chains, prioritize data at risk, and consider hybrid approaches to reduce risk during transition.
