Yvette Lejins isn't your average cyber security executive - she's the kind of leader who has spent her career making sure adversaries don't ruin your day, whether you're booking a budget flight to Bali or ordering midnight snacks in Seoul.

With a resume that reads like a global tour of high-stakes digital protection, Yvette has held the keys to the kingdom at some of the most interesting companies you've actually heard of. Think: tech giants, airlines, logistics empires, and pre-IPO unicorns.

She's a Fellow of the Australian Information Security Association and takes her responsibility incredibly seriously of keeping entire corporations from becoming cyber headlines.
