Head of Information Security and IT, Elliot Colquhoun. Airwallex is an Australian finance unicorn ($1bn+ valuation), and Colquhoun runs its IT and information security operations. The company has spent the past two years overhauling its application landscape and upgrading computers - a 50/50 Windows/Mac end-user environment. One of the reasons to do this, however, is that Colquhoun believes the state of internal systems is a signal to developers and builders about the quality that should be built into customer-facing products. The idea is to set a high internal bar, which then gets reflected in the products. IT and infosec also makes itself available to product teams to provide input and guidance.
