Definition
AES-256 is a strong encryption standard used to secure data both at rest and in transit. It is a common baseline for protecting sensitive call and customer data. In voice AI, live audio is typically protected in transit with TLS and SRTP, while stored recordings and transcripts are encrypted at rest with AES-256. See our security and compliance guide for what to ask vendors about key storage and access.
Why it matters
Strong encryption is a standard expectation in vendor security reviews and supports compliance claims.
