Post-quantum crypto inventory: NeoShield PQC Analyzer vs a manual audit
You need to find quantum-vulnerable crypto (RSA, ECC, DH) and plan a NIST PQC migration.
The status quo for post-quantum readiness is a manual audit: grep the codebase, list algorithms in a spreadsheet, and cross-reference NIST guidance by hand. NeoShield's PQC Analyzer does the inventory automatically from code, TLS config, or a certificate list, classifies each algorithm (broken by Shor, weakened by Grover, or quantum-safe), flags harvest-now-decrypt-later exposure, and outputs a phased NIST migration plan.
Feature comparison
| Capability | NeoShield PQC Analyzer | A manual spreadsheet audit |
|---|---|---|
| Automatic algorithm inventory | ✓ Yes | Manual |
| Shor / Grover risk classification | ✓ Yes | Manual |
| NIST mapping (ML-KEM/ML-DSA/SLH-DSA) | ✓ Yes | Manual |
| Harvest-now-decrypt-later flagging | ✓ Yes | Easy to miss |
| Phased migration roadmap | ✓ Yes | Manual |
| Repeatable in seconds | ✓ Yes | — No |
When NeoShield is the better fit
- You want a fast, repeatable crypto inventory and a NIST-aligned plan.
- You're starting PQC migration and need to prioritize key exchange first.
The verdict
A spreadsheet works, but it's slow and easy to get wrong. NeoShield's PQC Analyzer gives you the same inventory and a NIST plan in seconds — and you can re-run it as code changes.
