We'll be back with new episodes soon. For now we flash back to our discussion with Zip Co's former director of security and IT, Peter Robinson. Original Description: When Zip’s director of security and IT Peter Robinson joined the company two-and-a-half years ago, he was its only security staffer.  The company - ASX-listed and a major player in the ‘buy now, pay later’ (BNPL) boom - has scaled up rapidly in that time, growing from 100 people overall to over 1000. The story of that scale-up, and the technology challenges it brought, is told in this week’s CXO Challenge interview on the iTnews podcast.
