Quantum Readiness: "Harvest Now, Decrypt Later"

In the cybersecurity world, we often talk about threats in the present tense. But the Quantum threat is unique: it is a threat from the future that breaks the past.

The HNDL Strategy

Nation-state adversaries are currently scraping encrypted traffic (VPN tunnels, SSL sessions, encrypted emails) and storing it in massive data centres. They cannot read it yet. But they know that within 5-10 years, a Cryptographically Relevant Quantum Computer (CRQC) will break RSA and ECC encryption in seconds.

Critical Insight: If your data has a shelf life of >7 years (e.g., mortgages, medical records, trade secrets), it is effectively already compromised if captured today.

What Can You Do Today?

You cannot buy a quantum computer, but you can become “Crypto-Agile.”

Inventory: You cannot protect what you don’t know. Discover where you use RSA-2048.

Isolate: Identify long-life data. Keep it separate from ephemeral data.

Migrate: Begin testing NIST-approved Post-Quantum Cryptography (PQC) algorithms like CRYSTALS-Kyber.

Cloudgap’s stance: Do not panic, but do not delay. The migration to PQC will be the largest Y2K-style event in security history.
