I've been through SOC2 certifications in a few jobs and I'm not sure it makes you bullet proof, although maybe there's something I'm missing?
But all it means in the end is you can read up on how a company works and have some level of trust that they're not lying (too much).
It makes absolutely zero guarantees about security practices, unless the documented process make these guarantees.
I mean ideally a proper SOC2 would mean there are processes in place to reduce the likelihood of this happening, and then also processes to recover from if it did ended up happening.
But the end result could've been essentially the same.
