Sectors We Serve
Quantum risk is sector-specific. So is our approach.
Every sector faces a distinct combination of regulatory requirements, data retention obligations, and threat profiles. Qontomcrypt's assessments and implementations are tailored to the specific context of each industry.
Banking & Financial Services
Protect payment systems, customer data, TLS, PKI, HSMs and long-retained records.
Financial institutions hold decades of transaction records, customer data, and contractual documents — all prime targets for harvest-now-decrypt-later attacks. Payment infrastructure, PKI hierarchies, HSMs and TLS endpoints are deeply dependent on classical cryptography that a quantum computer will break.
Regulatory frameworks including SAMA, CBUAE, and RBI are actively developing quantum-safe requirements. Institutions that begin PQC migration now will be better positioned to meet those requirements — and to protect long-retained records that adversaries may already be harvesting.
Cryptographic assets at risk
Payment system PKI
RSA and ECC certificates underpinning card payment authorisation, interbank messaging and settlement systems.
Customer-facing TLS
TLS endpoints protecting online banking, mobile applications and API gateways — high-capturability targets for HNDL attacks.
HSM key hierarchies
Hardware security modules managing master keys, PIN encryption keys and signing keys across payment and custody infrastructure.
Long-retained records
Transaction archives, customer records and contractual documents with 7–30 year retention requirements — within the HNDL window.
Interbank communications
SWIFT, correspondent banking and interbank messaging infrastructure dependent on classical digital signatures.
Identity and access
Digital identity infrastructure, certificate-based authentication and privileged access management systems.
Key challenges
- Long-retention transaction and customer records within the harvest-now-decrypt-later window
- Payment infrastructure deeply dependent on classical PKI and HSM key hierarchies
- Cross-border data flows with multiple regulatory jurisdictions and conflicting timelines
- Real-time payment systems requiring low-latency cryptographic operations
- Complex vendor and third-party dependencies across the payment ecosystem
- Legacy core banking systems with embedded classical cryptography

Protect citizen data, national systems and long-lived archives.
Government and public sector organisations hold some of the most sensitive and long-lived data in existence — citizen records, national security information, classified archives and critical system configurations. Nation-state adversaries with quantum development programmes are the primary threat.
Harvest-now-decrypt-later is not a future risk for government — it is an active threat today. Data classified as sensitive today may still be sensitive in 20 years. Quantum-safe cryptography is a national security imperative, and regulators including NESA are developing mandatory requirements.
Cryptographic assets at risk

National identity, civil registration, tax, social services and benefits systems holding sensitive personal data with long retention requirements.
Classified archives
Long-lived classified and sensitive government records — intelligence assessments, policy documents, diplomatic communications — with indefinite retention.
National PKI infrastructure
Government certificate authorities, national identity PKI and digital signature infrastructure underpinning public services.
Inter-agency communications
Secure communications between government agencies, ministries and allied nations — dependent on classical key exchange and digital signatures.
Critical system configurations
Encrypted configuration data, firmware signing and secure boot chains for national critical systems and infrastructure.
Law enforcement and judicial
Criminal records, court documents, surveillance data and legal proceedings with strict confidentiality and long retention requirements.
Key challenges
- Nation-state adversaries with active quantum development programmes and long-term data collection strategies
- Classified and sensitive data with indefinite or very long retention requirements
- Legacy systems across critical government infrastructure with limited update cycles
- Interoperability requirements with allied nations and international partners
- Complex procurement and approval processes that extend migration timelines
- Strict data sovereignty and residency requirements limiting deployment options

Request a PQC Discovery BriefingHealthcare
Protect patient records, medical imaging, research data and connected systems.
Healthcare organisations are uniquely exposed to quantum risk. Patient records must be retained for decades — often 30 years or more — and contain highly sensitive personal and medical data. A quantum-capable adversary harvesting records today could decrypt them well within the retention window.
Medical imaging archives, genomic research data, clinical trial records and connected medical devices all depend on classical cryptography. The combination of long retention requirements, high data sensitivity and complex legacy infrastructure makes healthcare one of the highest-priority sectors for PQC migration.
Cryptographic assets at risk
Patient record systems
Electronic health records, clinical notes and patient history systems with 30+ year retention requirements — prime HNDL targets.
Medical imaging archives
PACS systems storing DICOM imaging data — X-rays, MRI, CT scans — with long retention and high sensitivity.
Genomic and research data
Genomic sequencing data, clinical trial records and research datasets with permanent or very long retention requirements.
Connected medical devices
IoT medical devices, infusion pumps, monitoring systems and diagnostic equipment with embedded classical cryptography.
Health information exchange

- Complex supply chains with third-party data processors, cloud providers and medical device vendors
- Strict regulatory requirements for data integrity and audit trails alongside confidentiality
- Resource constraints and operational continuity requirements limiting migration windows

Request a PQC Discovery BriefingCritical Infrastructure
Protect operational technology, industrial systems, communications and supplier ecosystems.
Critical infrastructure operators — energy, water, transport, telecommunications — face a unique challenge: operational technology systems with 20–30 year lifespans that cannot be easily updated. Quantum-safe cryptography must be designed into these systems now, before the quantum threat matures.
OT environments present distinct cryptographic challenges: air-gapped networks, real-time operational requirements, strict latency constraints and complex vendor dependencies. A disruption to cryptographic infrastructure in a critical system is not a software bug — it is an operational failure with potentially catastrophic consequences.
Cryptographic assets at risk
SCADA and ICS systems
Supervisory control and data acquisition systems and industrial control systems with embedded classical cryptography and long operational lifespans.
Operational communications
Encrypted communications between control centres, substations, field devices and remote monitoring systems.

Supplier and vendor connections
Cryptographically protected connections to equipment vendors, maintenance contractors and supply chain partners.
Operational data archives
Long-retained operational logs, sensor data, maintenance records and incident reports with regulatory retention requirements.
Key challenges
- OT systems with 20–30 year operational lifespans that cannot be patched or updated on standard IT timelines
- Air-gapped and isolated network environments requiring offline or physically-delivered cryptographic updates
- Real-time operational requirements with strict latency constraints that limit algorithm choices
- Complex vendor and supply chain dependencies with long lead times for cryptographic updates
- Safety-critical systems where a failed cryptographic migration could cause operational disruption
- Limited cryptographic expertise within OT operations teams
