Quantum computers sound like the distant future, but the threat they pose to cryptography is entirely real today. Classic methods like RSA and ECC, which protect almost the entire internet, will become vulnerable once quantum machines reach sufficient power.

And most alarming: you don't need to wait for "Q-day". Attackers are already applying the "harvest now, decrypt later" tactic — stealing encrypted data today to crack it once technology allows.

Why this matters to you now

If your data needs to stay confidential for years to come — health records, financial records, intellectual property — it is already at risk. Encryption that is secure today may be worthless in 5–10 years.

The road to readiness

• Take inventory of all the cryptography used across your systems
• Identify data with a long confidentiality lifespan
• Transition to NIST's post-quantum cryptography standards
• Building "crypto-agility" — the ability to quickly swap algorithms
• Set quantum-resilience requirements for your suppliers

Early preparation is an advantage

Migrating to post-quantum cryptography isn't done in a week — it takes planning, inventory and testing. The companies that start today will be ready when others are only just realizing the problem.
