IBM Z Crypto Discovery & Inventory vs SandboxAQ: Side-by-Side Comparison (2026)

Short answer

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 preparing for post-quantum cryptography migration should start with AQtive Guard, which maps cryptographic exposure across your entire infrastructure and identifies which assets need rekeying first. The platform covers NIST PR.PS and PR.DS through cryptographic vulnerability mapping, giving you the threat inventory most organizations lack before they touch quantum-safe algorithms. Skip this if you need certificate lifecycle automation for today's RSA and ECDSA environments; AQtive Guard is built around tomorrow's problem, not managing your current PKI operations.
