Quantum computers aren't breaking RSA encryption yet. But they will. And when they do, every system relying on current cryptographic standards becomes vulnerable overnight. The fix - post-quantum cryptography - requires finding every instance of vulnerable encryption in your infrastructure and replacing it with quantum-resistant algorithms.
Google Cloud's QIZ platform automates that discovery and transition process. It scans your infrastructure, identifies cryptographic dependencies, maps them to quantum-safe alternatives, and helps you manage the compliance requirements around the migration. It's infrastructure for a problem most organizations haven't started thinking about yet.
The Inventory Problem
Here's what makes quantum safety messy: you don't know where all your encryption lives. It's in TLS certificates, database connections, API authentication, file storage, backup systems, third-party integrations, and legacy code nobody's touched in years.
QIZ runs automated discovery across your cloud infrastructure. It identifies cryptographic primitives - RSA keys, elliptic curve implementations, hash functions - and catalogs them with their usage context. Where they're used, what they protect, what depends on them.
That inventory is the starting point. You can't migrate what you can't find. And manual discovery at enterprise scale is effectively impossible - the infrastructure is too large, too distributed, and too dynamic.
Active Governance
Once you have the inventory, QIZ provides what Google calls "active governance" - ongoing monitoring of cryptographic usage with automated compliance tracking. When a new service spins up using a vulnerable algorithm, QIZ flags it. When a certificate needs rotation to a quantum-safe alternative, QIZ tracks the deadline.
The compliance angle matters because regulatory pressure is coming. NIST finalized post-quantum cryptography standards last year. Government agencies have migration deadlines. Industries handling sensitive data - finance, healthcare, defense - will face requirements to demonstrate quantum readiness.
QIZ positions itself as the platform that proves compliance. Not just "we migrated our encryption" but "we have continuous monitoring, documented coverage, and audit trails showing when and how each cryptographic component was replaced".
The Migration Path
QIZ doesn't flip a switch and make your infrastructure quantum-safe. It provides the roadmap and tooling for a staged migration. Prioritize high-risk systems, test quantum-safe alternatives, validate performance impact, roll out replacements incrementally.
The platform integrates with Google Cloud's key management system, certificate authority, and IAM controls. When you're ready to migrate a component, QIZ handles the configuration changes, key rotation, and verification that the replacement works correctly.
What's interesting is the timing. Quantum computers capable of breaking RSA don't exist yet. But encrypted data captured today can be stored and decrypted later - the "harvest now, decrypt later" threat. Organizations with data that needs to stay secure for decades have to migrate now, even though the threat isn't immediate.
Who This Is For
Right now, QIZ is relevant for organizations in three categories: those with regulatory requirements to demonstrate quantum readiness, those handling data with long confidentiality requirements, and those technically sophisticated enough to care about a threat that's still years away from materializing.
For most businesses, quantum cryptography isn't urgent. But infrastructure migrations take years. By the time quantum computers become a practical threat, the window to migrate safely will have closed. QIZ is betting that forward-looking organizations start now, rather than scrambling later when the threat becomes real.
The platform also surfaces a broader pattern: security is moving from reactive (fix breaches) to predictive (prevent future threats). QIZ automates preparation for a threat that doesn't exist yet. That's a different kind of security thinking - and it requires infrastructure that can discover, monitor, and migrate systems at scale without manual intervention.
