What is PQC Migration?
PQC migration is the gradual replacement of classical encryption methods like RSA and ECC with quantum-resistant, NIST-standardized algorithms. It touches an organization’s entire cryptographic infrastructure — from certificates to TLS to key management. Because it affects every system, process, and standard involved, it’s a multi-year effort rather than a one-time update.
How PQC Migration Succeeds in Four Phases
Start Your PQC Migration with MTG
PQC migration is the central step in making your IT infrastructure quantum-safe. MTG supports organizations through a structured migration to post-quantum algorithms – from taking inventory of your cryptographic assets to a fully PQC-ready infrastructure. We integrate these quantum-safe algorithms directly into the MTG ERS® platform, with its components for PKI, CLM, and KMS.
In an ongoing research project with CryptoNext Security, we’re advancing this crypto inventory into an active tool for automation and risk management.
The most dangerous attack scenario is known as “Harvest Now, Decrypt Later”: attackers collect encrypted data today so they can decrypt it once sufficiently powerful quantum computers become available. Organizations that delay PQC migration are therefore also putting data transmitted today at risk.
