How Hugh is building a better working world

“I support organisations fighting the evil of cyber crime by helping them understand cyber threats, protect their customer information and prevent the flow of funds and data to cyber criminals.

I help businesses to prepare for cyber attacks through cyber crisis exercises, which use immersive scenarios for board and executive teams to safely experience how a serious cyber attack could affect their business and build the right decision-making structures to manage the situation effectively.

I also help organisations measure their cybersecurity capability maturity and benchmark it against industry peers, so they can align precious resources to the areas of greatest business need.

Finally I help organisations conduct so-called ‘red team’ exercises, where our ethical hacking teams use the tools, tactics and procedures of real-life cybercriminals to identify exploitable weaknesses that present risk to the business and recommend how to fix them.”
