Just to advise anyone running 3DS on Site Builder, if the verification is processed in an iframe, your customers may well experience issues when running Google Chrome, as Netsuite doesn't recognise them when they return from 3DS verification. This appears to be due to the issue @Fourth Wave Consulting stated above. Cybersource document this in their support article 000003229. I've got a case open with support about this. If anyone else is similarly affected, I'd be keen to know.
