PQC in manufacturing

Manufacturing supply chain resilience

Problem: Proprietary designs and IoT-enabled machinery in the supply chain were exposed to long-term espionage and sabotage risks under legacy encryption.

Solution: We deployed hybrid post-quantum encryption modules on production lines, ensuring telemetry and IP remained secure. Keys and entropy were locally governed, supporting ISO 27001 compliance and sovereign IP protection.
PQC in Fintech

Fintech payments safeguarded

Problem: A leading financial services provider faced pressure to safeguard mobile and API-driven payments against both quantum threats and emerging compliance mandates (APRA CPS 230, PCI DSS).

Solution: We integrated quantum-safe APIs with agile key rotation and hybrid TLS handshakes, ensuring customer trust, forward confidentiality, and full auditability under regulated financial standards.
PQC in Blockchain

Blockchain future-proofing

Problem: Smart contracts, wallets, and consensus protocols were at risk of long-term compromise under quantum adversary models.

Solution: We implemented lattice-based key exchange and hash-based digital signatures across the blockchain stack, securing transactions and ensuring compatibility with NIST PQC recommendations while maintaining ecosystem interoperability.
PQC in Digital ID

Digital ID quantum upgrade

Problem: Identity frameworks relying on RSA/ECDSA were vulnerable to future compromise, threatening the integrity of banking users.

Solution: We delivered ML-DSA based signature schemes and hybrid KEM overlays for authentication, aligned with IRAP and sovereign data residency mandates.
PQC in Healthcare

Healthcare (pilots)

Problem: Sensitive health records, diagnostic imaging, and IoT-linked medical devices risked interception and tampering over classical TLS.

Solution: We are piloting post-quantum cryptography in medical devices, ensuring HIPAA and NCA compliance, with future-proof audit trails for regulators.
PQC in Energy

Energy & critical infrastructure (pilots)

Problem: National energy operators faced vulnerabilities in SCADA systems and smart grids, where compromise could disrupt essential services.

Solution: We're integratingPQC into control-plane signing and grid telemetry encryption, ensuring resilience against advanced threats and alignment with NERC CIP and local cyber mandates.
PQC IoT

IoT device security hardened

Problem: Industrial IoT deployments required ultra-low-latency data exchange but were exposed to remote compromise and long-term decryption threats.

Solution: We embedded PQC key exchange into sensor firmware and orchestration layers using a pre-shared key agreement with a central server, securing data without compromising performance, aligned with ISO/IEC 30141 IoT Reference Architecture.
PQC in AI

Artificial Intelligence (AI)

Problem: AI pipelines, from training data to inference endpoints, face risks of tampering and data leakage, with regulators demanding stronger privacy measures.

Solution: We applied PQC to secure inter-organizational data sharing, protect stored model artifacts, and enforce zero-trust access with quantum-safe signatures. We're also piloting Homomorphic encryption for privacy-preserving model training at scale.
