Quantum is coming. When is up for debate. If tomorrow a nation-state announced it had a quantum computer breaking encryption in mere minutes or seconds, would your data be secure? There are ways to mitigate the threat now, before it actually arrives. Crypto-agility is a relatively new term which implies the ability to rapidly change the encryption algorithm being used to encrypt data, be it the data is in motion or at rest. Double-encryption is another method. Employing post-quantum cryptographic algorithms is still, another.
