In late July 2026, Apex AI and Terra Quantum announced a joint solution that embeds NIST‑standardized post‑quantum cryptography into a robotic software platform and a cloud‑based control system. The offering secures edge‑to‑cloud communications for long‑lived, connected assets such as autonomous machines, software‑defined vehicles and defense platforms, while preserving existing application architectures. By early August, industry guidance expanded the focus to a broader enterprise landscape. Organizations were urged to adopt Quantum Key Distribution (QKD) alongside post‑quantum cryptography (PQC) to detect interception, protect data against future decryption, and enable more frequent key rotation. Experts emphasized that PQC migration should begin with a comprehensive cryptographic inventory—mapping algorithms, certificates, protocols, and keys—rather than a simple algorithm swap. In mid-August, Microsoft joined the transition efforts by prioritizing threat modeling as a core component of its migration strategy, aiming to secure critical products and services by 2029. Microsoft recommends transitioning RSA, ECDH, and Diffie-Hellman key establishment to ML-KEM, while using ML-DSA, SLH-DSA, or composite signatures for signing. Researchers further advised that because automated scanning may overlook controls in operating systems or hardware, deep threat modeling is necessary to trace data movement and identify trust boundaries. By late August, cybersecurity firms and standards bodies furthered these defenses. Akamai announced the general availability of end-to-end PQC across its Enhanced TLS ~~network, covering client-to-edge, mid-tier, and origin segments~~ network to mitigate ‘harvest now, decrypt later’ attacks. Simultaneously, Japan’s Cyber Security Cloud, Inc. began technical verification for PQC integration into its ‘Kogeki Shadan-kun’ Web Application ~~Firewall, focusing on hybrid key agreement methods and~~ Firewall. Additionally, the ~~performance impact of PQC on web communications.~~ Trusted Computing Group (TCG) released guidance for businesses to evaluate if device vendors provide genuine protection through quantum-safe identities and hardware-anchored trust in Trusted Platform Modules (TPMs).
