HNDL Data Risk Calculator
5 questions. See whether your data profile makes you a priority target for harvest-now-decrypt-later collection.
Is your data already being harvested?
Harvest-now-decrypt-later (HNDL) is the strategy where adversaries collect encrypted data today and store it — waiting for a sufficiently powerful quantum computer to decrypt it in the future.
Whether this matters to your organisation depends on five specific factors. This calculator scores your exposure across each one — in plain English, in under two minutes.
