Everyone else is using the plain English definition because it’s accurate.

Okta is intentionally using their own definition to down-play what’s happened.

A breach is simply ‘to overcome defences’ (ie to get access to something you shouldn’t). In this case their defence against someone else accessing the super user application was the support employee and their credentials, but this defence was clearly overcome by the hackers.

I agree that they need to stop using the word.
