Quantum-safe security across sectors

Explore how post-quantum cryptography applies across critical sectors, from government and finance to healthcare and critical infrastructure.

Applications across critical sectors

Post-quantum cryptography applies differently depending on the sector, the regulatory environment, and the cryptographic surfaces at risk. These scenarios illustrate how ExeQuantum's platform and implementation approach addresses the challenges most commonly faced across government, finance, healthcare, and critical infrastructure.

Each scenario reflects the technical problems we solve and the architectural approach we take. For specific client engagements and reference conversations, contact us directly.

Applied across finance, manufacturing, and more

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: Hybrid post-quantum encryption modules deployed 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: Quantum-safe APIs integrated 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: Lattice-based key exchange and hash-based digital signatures implemented 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: ML-DSA based signature schemes and hybrid KEM overlays for authentication, aligned with IRAP and sovereign data residency mandates.
PQC in Healthcare

Healthcare

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

Solution: Post-quantum cryptography in medical devices, ensuring future HIPAA compliance, with future-proof audit trails for regulators.
PQC in Energy

Energy & critical infrastructure

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

Solution: PQC integrated 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: PQC key exchange embedded 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: 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.
