Discover your cryptographic landscape. Plan the migration. Run it as a program.
A practical lifecycle for post-quantum migration in government agencies and commercial enterprises, and the platform to operate it.
Stage 1: Discover your cryptographic landscape
Before an organization can migrate its cryptography, it needs to know what its cryptographic landscape actually looks like. Conventional inventories list servers, applications and endpoints. They rarely capture where cryptography is used, which algorithms, which certificates and PKI relationships matter, which applications embed cryptographic libraries, which vendors control the migration path, or which systems protect data that must stay confidential for years.
Quantum Iryx Systems builds Cassian, the operational control plane for cryptographic modernization. Cassian helps organizations understand where their cryptography lives, plan and govern post-quantum migration, and manage Isidore Quantum and other secure infrastructure over time.
Finding an RSA certificate is useful. Knowing that it belongs to a revenue-critical application, protects data with a 15-year confidentiality requirement, relies on a third-party vendor and cannot currently support an alternative algorithm is what lets you act.
Stage 2: Plan the migration
PQC migration is not 'find RSA, replace it with ML-KEM'. Real migrations involve business criticality, data longevity, dependencies, PKI, application architecture, vendor readiness, legacy systems, interoperability, testing, maintenance windows, budget, ownership, sequencing, rollback, validation and governance.
Stage 3: Execute, validate, and keep it that way
Cryptography will keep changing. Algorithms will be deprecated, replaced and updated, and requirements will differ by regulator and by system. The durable capability is crypto-agility: cryptography that is visible, governed, configurable, monitored and replaceable. No organization should need a decade-long emergency project the next time an algorithm changes.
Two audiences, one lifecycle
Federal policy now sets planning and transition milestones, and agencies are treating PQC as a multi-year transformation rather than a reporting exercise. Cassian supports the inventory, prioritization, planning and evidence that programs require. Government engagements are coordinated with Forward Edge-AI.
The same lifecycle applies to banks, insurers, healthcare providers, manufacturers, telecoms and technology companies, where large application estates, complex PKI, long-lived data and third-party dependencies make migration slow and expensive to get wrong.
Where Cassian fits
Cassian is the operational control plane for this lifecycle. It organizes cryptographic and device assets, attaches the context needed to prioritize, supports planning and governance, coordinates lifecycle actions on managed infrastructure, and keeps an auditable record of what changed.
