  4. Inventory and Risk Assessment
  5. Migration Roadmap and Timeline
  6. Hybrid Deployment Strategies

The Quantum Imperative

Quantum computing poses a fundamental threat to the cryptographic algorithms that protect enterprise communications, data, and digital identities today. While large-scale quantum computers capable of breaking RSA and ECC are still years away, the “harvest now, decrypt later” threat means organizations must begin preparing immediately.

This whitepaper provides a practical, phased approach to post-quantum readiness that balances urgency with operational reality.
