Based on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
IBM Z Crypto Discovery & Inventory
Enterprise organizations running IBM Z mainframes need IBM Z Crypto Discovery & Inventory to map cryptographic sprawl across legacy systems where key inventories don't exist and policy enforcement is manual. The tool addresses the ID.AM and ID.RA gap that leaves most mainframe shops unable to answer basic questions about algorithm strength, key length, and regulatory exposure across their infrastructure. Skip this if your organization uses modern cloud-native stacks exclusively; the value collapses outside the IBM Z ecosystem where crypto visibility is already native to your deployment model.
Enterprise security teams managing cryptographic decay across complex supply chains need Quantanaut because it finds broken encryption and outdated TLS configs that vulnerability scanners skip entirely. The agentless discovery model means you map cryptographic risk using existing tool data without new agents, and the structured PQC transition guidance directly addresses NIST CSF 2.0's GV.SC supply chain requirement. Skip this if your organization hasn't inventoried cryptographic assets yet; Quantanaut assumes you know what you're protecting.
