PKI modernisation
Certificate authority design, automated issuance and the end of expiry-driven outages.
Crypto Security
Cryptography that survives the next decade
Keys outlive the systems that created them. ASNC builds cryptographic estates with clear ownership, provable lifecycle control and a credible path to post-quantum algorithms.
Key management
KMS and HSM architecture, key hierarchies, rotation policy and separation of duties.
Data protection
Tokenisation, field-level encryption and confidential computing for sensitive workloads.
Post-quantum readiness
Cryptographic inventory, crypto-agility patterns and staged migration to NIST PQC standards.
Programme
From cryptographic inventory to crypto-agility
You cannot migrate what you cannot see. Every engagement begins with discovery of algorithms, key stores, certificates and protocol usage across the estate.
- Cryptographic bill of materials across applications, infrastructure and vendors
- HSM topology design for FIPS 140-3 and Common Criteria assurance levels
- Certificate lifecycle automation with ACME and short-lived certificates
- Payment cryptography and key ceremony design for PCI environments
- Secrets management migration away from embedded credentials
- Crypto-agility patterns so algorithm changes are configuration, not rewrites
- Quantum-risk assessment for long-lived confidential data ('harvest now, decrypt later')
- Staged adoption of ML-KEM and ML-DSA in TLS, code signing and VPN paths
Why now
Data encrypted today can be decrypted later
Adversaries capture encrypted traffic now in anticipation of future cryptanalytic capability. If your confidentiality requirement extends beyond a decade — health records, state secrets, long-dated financial contracts — post-quantum planning is a present-day obligation, not a future one.
