Organizations cannot prioritize cryptographic migration when they do not know where algorithms, keys, certificates, libraries, protocols, and hardware dependencies are used. Inventory work combines available records, configuration review, discovery tooling, architecture evidence, and vendor documentation into a maintainable view of cryptographic dependencies.
Cybersecurity — Quantum Security & Post-Quantum Readiness
Cryptographic Inventory & Dependency Mapping
Build visibility into the cryptography your systems, applications, data flows, devices, and suppliers depend on.
Who this is for
- Organizations beginning post-quantum migration planning
- Teams with incomplete certificate, key, or software dependency records
- Product and platform owners responsible for multiple applications or vendors
- Security teams improving cryptographic governance and crypto-agility
What's included
Algorithms and protocols
Record relevant public-key, symmetric, and hashing algorithms and the protocols or business functions that use them.
Certificates and key dependencies
Map certificate use, issuing chains, ownership, expiry, key-management boundaries, and dependent services without collecting private key material.
Applications and software
Identify cryptographic libraries, versions, application dependencies, firmware, CI/CD components, and code or configuration that constrains algorithm changes.
Infrastructure and hardware
Document relevant TLS, SSH, VPN, email, identity, PKI, HSM, TPM, smart-card, secure-enclave, cloud KMS, and device dependencies within scope.
Vendors and data flows
Track third-party services, managed platforms, external integrations, protected data, retention requirements, and follow-up owners.
What you receive
- A scoped cryptographic inventory or inventory baseline
- Dependency relationships and ownership gaps
- Identification of quantum-vulnerable public-key dependencies
- Discovery limitations and vendor evidence gaps
- Priority recommendations for validation and migration planning
- A maintainable data model for future updates
Scope & limitations
- Discovery tools do not reveal every embedded or vendor-controlled use of cryptography.
- Findings distinguish confirmed evidence, inferred dependencies, and items requiring supplier validation.
- Private key material is not included in the inventory.
Common questions
Is a certificate inventory enough?
No. Certificates are important, but migration planning also requires protocols, libraries, applications, hardware, data flows, vendors, and ownership information.
Can the inventory support work beyond quantum readiness?
Yes. A maintained inventory also supports certificate lifecycle management, technical compliance, incident response, architecture review, and broader cryptographic agility.
