We provided ongoing security risk assessment support to a major critical national infrastructure operator to give them greater visibility on the threat, risk and level of protection of their most critical asset locations. This multi-year project included over 120 individual assessments across a number of assets to reassure senior leadership that the critical national infrastructure network was being protected appropriately, identify potential opportunities for improvement, and spot major faults which could leave assets vulnerable. The project also aligned with the operator’s regulatory responsibilities for protecting infrastructure which was critical to national security.
