What is encryption key rotation?
Encryption key rotation is replacing an encryption key with a new one on a schedule or after a suspected compromise. It limits how much data any one key protects and how long a leaked key stays useful. Many teams rotate yearly, and managed key services can do it automatically.
What the buyer is really asking
Buyers want your key rotation cadence and whether it runs automatically or depends on someone remembering. Give the interval and the mechanism.
Other ways buyers ask it
Every one of these wants the same answer:
- “How often are encryption keys rotated?”
- “Is key rotation automated?”
- “How do you manage and rotate encryption keys?”
Evidence to have ready
- KMS settings showing automatic rotation
- The rotation cadence stated in your key management standard
- A record of the most recent manual rotation, if any keys rotate by hand
How Tyrvar answers this
Tyrvar treats every wording above as one question. You write the answer once, attach the evidence, and revisit it when your setup changes. Each buyer gets that approved answer no matter how their questionnaire words it. If you have not answered it yet, Tyrvar flags the question for you and does not make something up. Try it on your own questionnaire.
