Hi all, long time lurker here.
Quick straw poll on this issue: Out of those schools affected, how many of your school or MAT leadership teams are aware genuinely tracking this issue? Also, how many of your organisations (where affected) are treating this as a proper data breach?
I'm the IT Director for a large MAT and am intending to illustrate to our Board just how significant this issue is and the resulting action has been. I get the feeling reading this thread (unless I'm reading it wrong), that most schools are resigned to taking it on the chin and simply fixing any errors as opposed to taking significant action. In my view, this is a substantial failing by a major data processor and the way they've handled the issue is pretty appalling.
Keen on finding out what your situation is.
