String finiteness only fully proven order-by-order
String theory has been established as finite at the level of order-by-order perturbation theory, but the full non-perturbative finiteness is not proven; it is believed true based on the perturbative result and on duality symmetries that map the problem to cases known to be finite.

“First of all, at the level of computing perturbation theory, which means these order by order corrections, it has been established as finite. Okay. So there at least we know it's finite in that sense.”
