Encryption is probably the most over-credited technology in enterprise security right now.Not because it doesn't work — it does exactly what it was designed to do, reliably. The problem is the gap between what encryption actually solves and what most organizations believe it solves.Ask a senior security leader whether their data is protected and the answer is almost always framed around encryption. "We encrypt data at rest and in transit." "All our backups are encrypted." These statements are true — and they're all answers to a question that isn't the one regulators, forensic examiners, or insurers are actually asking.Encryption controls access. It answers one question well: can someone who isn't supposed to read this data read it?But there is a second question encryption is structurally incapable of answering: has this data changed since it was created? These are not variations of the same question. They're different problems requiring different solutions — and conflating them creates a gap that is showing up in incident investigations, insurance disputes, and regulatory proceedings with increasing frequency.
