The issue with Ariane V was the lack of integrated testing. If they had coupled the testing of the software with increased acceleration levels generated by a simulated Ariane V instead of an Ariane IV, they would have caught the issue.
But let's say this was something unexpected - then probably the only way to mitigate this would be a backup system - but this is an unmanned system - and Apollo/Saturn/Shuttle/Soyuz levels of redundancies is not required.

How could anyone believe this system was safe? No testing or requirements needed.
