The recent Optus data breach has thrust cyber security back into the national spotlight, with the impact devasting for both Optus and their customers.

Yet whilst the scale of this breach was unprecedented, it was only one amongst many, with breaches since involving MyDeal (Woolworths), Medibank and Costa Group. Further the NAB have reported receiving over 50 million attacks each month!
