Why It Matters

Quantum risk is not only a future decryption problem. It is a business risk today

RSA, ECC, Diffie-Hellman, and today’s public-key cryptography protect TLS, VPNs, software updates, identity systems, payments, cloud services, APIs, and critical data. A cryptographically relevant quantum computer could weaken or break these foundations. Sumeru helps organizations identify what is exposed, prioritize what matters, and migrate with control to a Post Quantum Cryptography (PQC) future.

Quantum computing threatens today’s widely used public-key cryptography

Long-lived sensitive data may already be exposed through harvest-now, decrypt-later risk

NIST has finalized the first major post-quantum cryptography standards. RSA/ECC based certificates deprecate starting 2030; no longer valid after 2035

Government and industry guidance is moving organizations toward cryptographic inventory, risk prioritization, and migration planning

PQC migration will affect applications, infrastructure, cloud, identity, certificates, vendors, and custom-coded systems

Organizations need crypto-agility so future algorithm changes do not require disruptive rewrites
