Dear Clare, it’s a privilege to have you with us today! You have a distinguished career in IT and information security consulting, were named one of the top CIOs in the UK, and have been responsible for IT infrastructure and cybersecurity in a large corporation. Can you tell us an anecdote about your career that still makes you chuckle when you remember it?

I inherited what I was told was a nearly completed project, which had been managed by another consultancy, to implement an upgraded certification authority (CA). The handover was all focused on ensuring the initial keys were set up securely and penetration testing the CA server. The key signing ceremony had been held – and then one of my team reported that it seemed the server wouldn’t generate any certificates. When questioned, the IT supplier explained that they had descoped the certificates from the project, as the client hadn’t provided any specification on them and had signed off on the design. They had delivered a fancy secure box which didn’t actually do anything! They even had the cheek to ask the client to pay them to host the box! We eventually got it all working and it was a lesson in the need to have people who actually understand security managing security projects.
