QIZ Cryptography Management Platform

Commercial

Post-Quantum Cryptography

QIZ is a cryptography management platform that discovers, prioritizes, remediates, and governs cryptographic assets across an organization's on-premises and cloud environments. The platform maps cryptographic assets against policy to reveal vulnerabilities and dependencies, including outdated protocols, weak encryption, and weak cipher suites, in both data in motion and data at rest. Findings are ranked by context, impact, and remediation effort, and QIZ provides a step-by-step remediation plan to address identified risks. QIZ is positioned to help organizations prepare for quantum computing threats by building visibility into where cryptography is used and enabling crypto-agility. It supports collaboration among CISOs, compliance teams, and application owners on a shared view of cryptographic risk and readiness. The platform integrates with existing infrastructure through an API-first approach, without requiring agents or network probes, though it notes room for other integration methods where applicable.</description> <parameter name="summary">Discovers, prioritizes, and remediates cryptographic risk for quantum readiness
