Their assessment helped us understand where we could strengthen our controls and prioritise future improvements. The guidance they provided was clear, practical and collaborative throughout. We now have a well-defined roadmap that supports our ongoing security strategy, and we are keen to work with them again to ensure we stay ahead of the ever-changing security threats."
