For portfolio controllers, cybersecurity is increasingly seen as a measure of value. If not managed properly, it can erode a company’s value over time, but if managed effectively, it can be prosperous.

How Paul is building a better working world

“We all build for the future. Whether you build a career, a company or a family, there are hard decisions, sacrifices, investments and risks every step of the way. Increasingly, the biggest threats to what we build are invisible, which makes them somewhat unpredictable and potentially catastrophic on multiple levels. As a security bloke, I’d like to think I’m doing my part to prevent that from happening.”
