Do you bring deep cyber technical knowledge with the ability to understand and articulate cyber security risks and trends across critical national infrastructure, including the threat vectors impacting energy, transport, water, digital infrastructure and social infrastructure assets?

Do you have client-facing skills that allow you to translate technical and operational technology (OT) findings into commercial and financial impact for infrastructure funds and corporate investors across the M&A lifecycle?

If so, then we would love to hear from you in connection with these new opportunities based within Aon’s multifaceted M&A Transactions Solutions (AMATS) practice, situated within our flagship London office!
