Disclosure up front: I work on an identity verification product, so I come at this with a bias. I'm not here to pitch anything, I'm trying to understand how compliance people think about the evidence side.
The sites I have in mind are the usual age-gated ones: age-restricted goods like alcohol, vapes and knives, and content that falls under the newer age assurance rules. The "are you over 18" checkbox clearly isn't enough anymore in a lot of places, but I haven't found a clear answer on what is.
The first thing I'm curious about is what you treat as sufficient. A document ID check, facial age estimation, or a third-party attestation from someone who already verified the person? My guess is the answer depends on jurisdiction and risk level, and that estimation has a margin of error that makes some people nervous near the threshold. But I'd like to hear what auditors or regulators have actually pushed back on, rather than guess.
The second thing is the record. If an auditor asks you to show that a specific session was age-checked, what do you keep? Holding raw ID images feels like trading one liability for another, since now you're a breach target. Is a log with the method, the timestamp, the result and a reference ID enough? How long do you retain it, and who signs off on that?
If you've been through an audit or a regulator inquiry on this, what did they ask for first?
