Quantum Threat
Why encrypted traffic is at risk today.
The "harvest now, decrypt later" model means adversaries can store encrypted data now and attempt decryption when quantum capability matures.
Harvest now, decrypt later
Long-retention sensitive data is especially exposed. Even if current ciphers remain secure today, intercepted traffic can become readable if future cryptanalysis or quantum capability reduces practical security margins.
Classical assumptions are changing
Security systems designed around classical hardness assumptions may need staged migration plans, especially where confidentiality windows extend over many years.
Transition takes time
Cryptographic transitions are operational projects, not simple switches. Enterprises and products need compatibility, rollout controls, and user-safe defaults while introducing quantum-resistant components.

QAL VPN response
QAL VPN keeps fast default operation while allowing users to enable optional post-quantum behavior where stronger long-term confidentiality is required.
