I haven't heard ISO or IEC company lawsuit against fraudulent companies, or maybe I'm wrong? show the proof.
I search if ISO alleged to be partners in debt settlement scam, which mean having ISO doesn't mean it to make the player safer
https://debanked.com/2017/09/isos-alleged-to-be-partners-in-debt-settlement-scam-in-explosive-lawsuit/Online casinos can use ISO 27001, this is the requirement for remote gambling businesses that want to get license in certain jurisdiction, I thought you all know that ISO 27001 is already a mandate from gambling commission?
Gambling providers like NetEnt and Evolution have ISO 27001.
